Yes, the D5s are the 'official' Handheld Universal Lunar Cameras (HULCs), but (a?) Z9 also got on-board at the 'last minute' (which means two years ago):
the morning after the launch i just randomly went onto their livestream and one of the astronauts was asking mission control for help on also using the gopros and iPhone cameras. i guess they have some. and he was struggling at getting a properly exposed photo with those. he said they were coming out super over exposed. but the D5 was working nominally. mission control said they'd get back to them about ideas on adjusting the gopros and iPhones. but it was funny to hear they're trying "new" tech and struggling with it up in space, and that 2005 D5 is still the champ :)
The SLR-like cameras have a bunch of manual modes so you can 'force' them to get something captured, and you can then perhaps 'fix it in post'.
Modern tech allows more people to capture more things more easily, but when the automation fails there aren't really many manual modes to fall back on.
he was struggling at getting a properly exposed photo with those. he said they were coming out super over exposed.
This is exactly what newbies experience when trying to photograph the moon from Earth. It's not intuitively obvious, but the light coming off the moon is essentially full-daylight bright. But the moon is small against a very black background, and depending on how the auto-exposure is operating, this often leads to guessing that the scene as a whole needs a lot more exposure.
I imagine that trying to photograph the Earth when a significant part of what's in view is experiencing daytime, is very much the same thing.
You have to wonder how unserious this can get. Given the unimaginable cost of this mission, they are faffing around as your typical aunt with Windows Home laptops and iPhones? Seriously?
I'll echo that "sheesh" in the other comment, too. They're so unserious compared to those super serious Apollo guys[1], right? After all, the Apollo folk never would've smuggled contraband for fun on the Moon[2]!
as a Hassie lover it made me a bit sad that they went with a D5 but hey, who cares about the camera, the picture was worth a billion bucks and it delivered.
It's so refreshing to be mesmorised by a picture in the age of shorts and reels.
From the EXIF we can infer that every setting was left at the default. No exposure comp, no contrast, no HSL, no lens correction and a linear tone curve. Just the default Adobe Color profile at 5400K.
The photograph appears to show nightime on Earth with just a sliver of daytime. Beyond cities in Iberia and along the coast of Africa, most of what we can see would be reflected light from the Moon? We are just past full moon on April 1.
1/4 exposure time so 250 ms of light. the light is coming from all the light sources in the universe, plus the moon, plus the sun's rays refracting through the atmosphere which happens even at night.
The natural blue light is coming from the oxygen in the atmosphere but it's so overwhelming in that spot that it turns the light pure white. The red/orangish is coming from particulates and the green/red from aurora. My favorite part I think is the very bottom where you can see the blue light taper off and not overwhelm the camera sensor and you can see the aurora with it. I love this photo so much.
> the light is coming from all the light sources in the universe, plus the moon
And all the others are negligible by many orders of magnitude compared to the moon. So it's really just the moon as far as this photo is concerned (except for the small sliver that's still illuminated by sunlight, including refracted sunlight).
Maybe it’s because I (like many) have experienced taking pictures at night and seeing the grainy result that _this_ image struck me as incredibly realistic.
Almost like I ran the grainy-to-real conversion in my mind and I felt like I was imagining seeing this in person. Beautiful image!
The Lightroom one was processed from raw. Also, by brightening it a lot, the noisy high-ISO grain becomes more apparent. Noise is famously incompressible, so it leads to a much larger file size.
But lossy-codecs job is to utilize psychovisual tricks to discard as much high-frequency information as possible, whilst remaining similar visual effects. If you increase the brightness in RAW and then re-encode the JPEG - more noise is being pulled up in the visual spectrum, therefor less of that information (filesize) is discarded.
For example, if you render Gaussian noise in photopea and export as JPEG 100% quality, it has 9.2MB. If you reduce the exposure by -2 it goes down to 7.8MB. That's partially because more parts of the noise are effectively black pixels, but also I believe because of the earlier mentioned effect.
Noise that's easier to see will not be compressed away by the JPEG compression. JPEG is basically just DCT + thresholding. Any higher amplitude noise is going to stay and increase the final file size.
Also, pulling more data from your 14 bit or 16 bit raws results in more noise in the end compared to the straight-out-of-camera 8 bit JPEGs.
It's beautiful as these all are, that one is probably my favorite. And as somebody else said it kind of feels more real seeing the grain like that. It's just beautiful. A side we never see quite like this.
I'd have probably shot it wide open at f/2.8 rather than cranking the ISO up to 51200. Incredibly impressed at the steady hands for a sharp image at 1/4 s shutter speed though! Maybe they just let the camera float in space with the mirror up, triggering it remotely.
The good low light performance was amazing for its time (10 years ago), and it still holds up decently today. But let's not kid ourselves -- it has been clearly surpassed by modern backside illuminated CMOS sensors like the one on the Z9.
EDIT: sorry, it seems I'm wrong. I just checked https://www.photonstophotos.net/Charts/PDR.htm and while the Z9 has the clear edge with 2 more stops of dynamic range at low ISO, the D5 actually pulls ahead at high ISO. Perhaps the technological improvements haven't been that much for the shot-noise dominated regime.
Good grief, that video suffers the YouTube-ism of "ramble on about how you don't understand X" for way too long.
Video alleges people think ISO makes the sensor "more sensitive or less sensitive". (I … don't think this is common? But IDK, maybe this is my feldspar.)
(The video also quibbles that it is "ISO setting" not "ISO" … while showing shots of cameras which call it "ISO", seemingly believing that some of us believe ISO is film speed, in a digital camera?)
Anyways, the video wants you to know that it is sensor gain. And, importantly, according to the video, analog gain, not digital gain.¹ I don't know that the video does a great job of saying it, but basically, I think their argument is that you want to maximize usage of the bits once the signal is digitized. Simplistically, if the image is dark & all values are [0, 127], you're just wasting a bit.
You would want to avoid clipping the signal, so not too bright, either. Turn your zebras on. (I don't think the video ever mentions zebras, and clipping only indirectly.)
The video does say "do ISO last" which I think is a good guideline. Easier said than done while shooting, though.
… also while fact checking this comment, I stumbled across Canon's KB stating to use as low an ISO as possible, which the video rails against. They should talk to Canon, I guess?
¹with the caveat that sometimes there is digital gain too; the video notes this a bit towards the end.
ISO changes the analog gain and in a way yes, it does make it more sensitive to a certain range of brightness.
This is because the ADC (analog to digital converter) right after can only handle so many bits of data (like 12-16ish in consumer cameras). You want to “center” the data “spread” so when the “ends” get cut off, it’s not so bad. Adjusting the ISO moves this spread around. In addition, even if you had an infinite bitrate ADC, noise gets added between the gain circuit and the ADC so you want to raise the base signal above the “noise floor” before it gets to the ADC.
Gain is not great — it amplifies noise too. You want as low ISO as possible (lowest gain), but the goal is not actually to lower gain; your goal is to change the environment so you
can use a lower gain. If you have the choice between keeping the lights off and using higher ISO versus turning on the lights and using a lower ISO, the latter will always have less noise.
Most photo cameras have one gain circuit that has to cover both dark and light scenes. Some cameras like a Sony FX line actually have two gain circuits connected to each photosite and you can choose, with one gain circuit optimized for darker scenes and the other optimized for brighter scenes. ARRI digital cinema line cameras have both and both are actually running at the same time (!).

Isn't ISO last the same as setting it as low as possible? Obviously it's always set to something, so I thought 'doing it last' means start with it low, set exposure & shutter, increase as necessary?
(Shutter speed being dictated by subject and availability of tripod, essentially it's just exposure & ISO which becomes about how much light there is and how it's distributed, I suppose.)
I'm not really into photography though, so perhaps that's all nonsense/misunderstanding.
Sure, but less grain is often worth it. There's a reason why fast lenses exist. The high quality lens being used here can probably still resolve 20 MP adequately even wide open.
I had that lens. It’s soft as fuck around the edges open.
Peak sharpness is about f/8. They should have had the D5 on aperture priority auto iso, pushed the exposure comp either way and then just fired at f/8 and let the camera make the decisions.
But they are astronauts not photographers :)
The modern Z lenses are far better and sharper open but much larger generally.
I would imagine since they are not circling the earth, that there will be pull of gravity and the camera would start to move relative to the spacecraft. But may not fast enough for a short exposure
Once you are out of the atmosphere and turn off your thrusters, you are on "fee fall" and the gravity on the camera, you and the spaceship produce the same acceleration and they cancel and it looks exactly like "zero gravity". It doesn't matter if you are in orbit around the Earth, going to the Moon.
Actually not quite correct. The camera and spaceship will generally have different starting positions of their center of gravity but the same starting velocity, leading them to drift apart.
The only real relevant thing for the photograph is rotation though as long as the camera doesn’t float in front of the window frame, and airflow is probably much more relevant for both points than gravity.
The gravity of the Earth (and moon, and everything else) is uniform (i.e. no gradient) on the scale of things the size of that capsule at the distance that capsule is from them, on the order of time of the exposure of that photograph. So the gravity (from any source) will pull on the spacecraft and on the camera in the same fashion.
To fully answer the question, the moon's gravitational gradient does pull on the Earth, the ocean closest to the moon, and the ocean furthest from the moon differently. But those are objects separated by thousands of kilometers, having hours of gravitational influence acting upon them.
Bad idea, shutter speed was 1/4 apparently (https://news.ycombinator.com/item?id=47632457), even the small rotational inertia everything in zero gravity gets from a human "dropping" it would probably be enough to be annoying, you'd get a better shot holding it.
I haven’t looked at the manual but it likely has the ability to flip and keep the mirror up for direct capture on the sensor without the mirror flipping up and down between exposures.
If you think they only took one shot, you're not a digital photographer)
In this special situation you get as many as you can a few dozen at least. Then only publish the one that looks the best. If it's f4 then f4 worked best.
The D5 doesn't have built in GPS, and adding it requires an attachment. I don't know if the smartphone app works on that model, but it is from the same year as my D5600 which does support it. The app provides GPS but also drains the battery fast. I turned airplane mode on after the first dead battery.
If you use a regular smartphone in space (or technically in orbit for this argument), it’s probably not going to get a fix because GPS receivers are required to stop locating when reaching some speed to not be export controlled. And that speed is picked so people don’t build missiles, orbital speed will be higher.
It's fun to think about tile dilation per the exif captured Create Date: "2026:04:03 00:27:39.26". I know it's negligible over the trip, but when they took it, was their time really "2026:04:03 00:27:39.25"?
"The Nikon D5 remains the camera of choice for the Artemis II mission and will be assigned primary photographic duties. It is a proven, highly-tested camera that the Artemis II team knows will excel in the high-radiation environment of space. However, as Artemis II Commander Reid Wiseman explained ahead of yesterday’s launch, he successfully fought to have a single Nikon Z9 added to Artemis II’s manifest."
There are more interesting details in the PetaPixel article, such as: "'That’s the camera that they’ll be using, the crew will be using on Artemis III plus, so we were fighting really hard to get that on the vehicle to test out in a high-radiation environment in deep space,' Wiseman said."
H/t to "SiliconEagle73" who linked to that PetaPixel article in the thread linked below.
I'd argue the D4s and D5 may be some of the best high ISO cameras I'm aware of maybe surpassed by that one canon video camera that can seemingly see in the dark (sorry I'm mobile) and the D3s. I think the lower numbers produce nicer looking max ISO noise but that's all preference. Sony has the A7s as well but as with some of these the overall resolution isn't extreme.
From what I recall reading its more or less, "we have established and validated processes for using the D5."
Its less about getting the best possible photo, more about making sure what they do take looks fine and doesnt waste a ton of time.
My only curiosity, and yeah I know orders of significance etc...
Buuuuut I wonder why they didn't consider a Z5[0][1] and the Z mount 14-24, or the Z5 with an adapter for the F mount 14-24....
There's at least a pound of weight savings on the table.
Specifically, I wonder if it's a fun reason? i.e. it would be interesting if there was a technical reason like 'IBIS fails miserbly' or 'increased sensor resolution adds too much noise' (even at that ISO you gave from the EXIF...)
[0] I'm really more of a Sony person but am thus keenly aware about importance of UX feel, so I tried to keep the question apples to apples here.
Edited to add:
[1] Per [0] I may be stupid in thinking the Z5 is a 'at least minimal' substitute so happy to learn something here.
Mass higher up the rocket costs several multiples more mass in propellant and propellant handling lower in the rocket. And the more deltaV you want the higher the multiplication. (If I remember right some weight issues of some kind on the Apollo capsule and or lander required a common bulk head in the first stage to make up the performance loss!)
However cameras probably fall into the variance in astoraunt weight somewhat.
I was confused when I first saw this photo, as I don't think I've ever before seen a nightside, moonlit Earth, exposed so that it looks like the dayside at a first glance. I wonder how many casual viewers actually realize it's the night side. A nice demonstration of how moonlight is pretty much exactly like sunlight, just much much dimmer. In particular it has the same color, even though moonlight is often thought of as bluish and sunlight as yellowish!
I've done several shoots lit only by the full moon. Doing long exposure, the images are as you stated not much different than an image taken during the day, except for looking at the sky and seeing stars.
I've also done video shoots with the newer mirrorless cameras and fast lenses shooting wide open again lit with nothing but the full moon. It again looks daylight on the image. As a bit of BTS, I recorded a video of the screen on the camera showing what it was seeing, and then pulled away and reframed to show essentially the same shot as the camera but it's just solid black. One of those videos was fun as we caught a bit of lens flaring from the moon, and you can actually see the details of the surface of the moon in the reflection. It was one of those things I just never considered before as flares coming from lights or the sun are just void of detail.
Thanks. Until you pointed out it's Earth at night, I had no clue what was supposed to be special about this photo (it appeared suspiciously pixelated for something 'high res', and neighbouring pixels seemed to contrast in colour rather than smoothly complementing as most photos do - but I guess that's random patches of city lights being captured by the camera). Cool stuff!
Something I haven't figured out is: what is that yellow/whitish smudge toward the center of the earth? It looks like camera glare or a reflection?
It explains why the image is so grainy. At first I was confused what that stripe to the left and the bottom was. But it’s just the window edge, and the noise isn’t stars.
(To be clear, the bright dots are stars [except the brightest one, in the lower right, is Venus I think], which makes this photo also a great demonstration that of course you can capture stars in space, you just have to expose properly!)
Who said you can't capture stars in space? What do you think the purpose of Hubble, JWST, etc are? There's also plenty of imagery taken from ISS that clearly show stars. I've definitely seen Orion in some of that imagery and it put a different perspective on the size of the constellations when seen from that angle.
I referred to the common question (or accusation) of why there are no stars in, say, the Apollo photos taken on the moon. The answer is, of course, that you can't see stars if you're exposing for something bright and sunlit, like the day side of Earth, or the lunar surface.
Of course. But they are not visible in the Chang’e photos on the dark side either. I think in the interview of the astronauts following the first Apollo Mission, a reporter asked for a confirmation that the stars were not visible because of “the glare” (an interesting question in itself). The explanation given was that the stars were not visible with the eye, but were visible with “the optics“.
I’m assuming the people who complain that there aren’t stars are the “moon landing faked” crowd… it’s hilarious to me that they think this vast conspiracy came together to fake that whole thing, and that they literally forgot to put a bunch of tiny 25-cent flashlight bulbs up poking through the black backdrop on the sound stage. Like, no one thought about the stars, or they couldn’t figure out how to do those “special effects” and just prayed no one would spot the error.
How do you know that they're stars? I believe they probably are stars as well (by visual comparison with a star chart, suitably rotated), but I've found no source for either claim.
I did find multiple sources, including TFA, for the brightest being Venus.
I’m talking about the grainy noise over all the black parts (actually over the Earth disk as well), including beyond the window edge. The window edge itself looks like a denser and brighter stripe of stars.
What does it look like to human eyes? Is there enough light for a person up there to see colour, or would it look like black and white (like a moonlit scene on the ground).
It’s a remarkable photo. You can see the aurora Australis at the top right of the image (it’s upside down, if there is such a thing - that’s the straits of Gibraltar at the lower left, and the Sahara above it - and the skein of atmosphere wrapping the entire planet. Those look like noctilucent clouds in the north, or possibly more aurora.
It really is gorgeous. You can see both auroral rings, then there's airglow, and city lights around Gibraltar and on the South American coast, and lightning flashes in the storm clouds over the tropics.
I don't think that's right. Sunlight is white in the atmosphere too. Scattering causes the sun, not the light, to look yellow, and so sunlight is thought of as yellow.
Scattering doesn’t really make the sun to appear yellow except when it’s low, behind a lot of air. When it’s above 30° or so it just looks blinding, neutral white (or non-blinding neutral white if there’s suitable cloud cover or other filter in front of it). Even though a lot of the blues are scattered around, the sun still looks just white when it’s high in the sky.
But when the sun does look yellow, its light is yellow too, that’s the definition of "looks yellow". And the golden hour paints everything in very iconic yellow-orange hues. The light as integrated over the whole sky is still white (modulo whatever’s scattered back into space), but the light that comes from the direction of the sun is clearly tinted yellow and the light from the rest of the sky is clearly tinted blue.
> But when the sun does look yellow, its light is yellow too, that’s the definition of "looks yellow".
Not quite; the sun is far away and is restricted to a tiny portion of the sky, but its light covers half the earth at a time. It is simultaneously true that the sun looks yellow and that the light we receive from it is white. It isn't the case that objects in direct sunlight are yellowed by that light; the yellow appearance when you look at the sun is something of an illusion.
> Even though a lot of the blues are scattered around, the sun still looks just white when it’s high in the sky.
That's fair, I was thinking of how night, or twilight, as a whole is associated with cool hues, but it's probably true that moonlight in itself is usually thought of as neutral white.
It's one of those stark reminders that there's no such thing as up or down in space, and something that disabuses me of the notion that I can truly comprehend "the enemy gate is down".
There's something a bit weird having these digital photos and crisp digital audio and video of the astronauts, and seeing pictures of mission control with flat screens after having grown up on grainy analogue video, crackly audio with lots of beeps, and mission control being choc full of CRTs being watch by men in short sleeve shirts with black ties and cigarettes.
I wish I could see a pic from today with the aurora. I was surprised to see the aurora in northern Europe a couple hours ago, it is very active right now.
Yeah, it is - unfortunately, it is rather cloudy in my area at the moment. Luckily, the weather was better during the 19./20. January event, which I'll carry forever in my heart.
It is funny if you think about it, imagine you arrive on a planet and there is nothing there, now what. Not saying it is not worth doing but it's like other aspects of life, about the journey. But yeah I think we are lucky to have this ability/get outside of our sandbox. Be aware of the bigger picture.
If you are interested in taking similar images, there are several satellites transmitting ‘full disk’ images like this, instead of a camera you need a dish or yagi a sdr and lna. Example satellites are Himawari 8, GOES 18, Fengyun 2H.
I remember watching grainy B+W ones in the 80s via a dish. It might have been a slow scan signal back then? It blew my mind watching the Earth live as a disk, seeing the weather in realtime.
I reject this sentiment. Ask anyone that you know who lived through the 1960s in a rich country. Their experience is nearly all the same: The air quality and environmental pollution was appalling. When my mother lived in Manhattan (New York City) in the 1960s, she would return home from work, and wipe her face with a cloth. The cloth had black streaks from all the pollution. Today, it is a different world in rich countries. They have cleaned up.
Finally: Yes, global warming is real, but the threat is different. I predict that we will far exceed the average increase in global average temperature, but we will survive. Yes, we will survive, but with some "scars".
We have done a lot better with faster and readily perceptible environmental problems.. from air pollution in China to acid rain killing forests and lakes in Europe. So yes, we should celebrate our successes too.
One of the objectives of the Artemis missions is to prepare for Mars travel, none of the objectives of Artemis are to view Earth as the only planet we have nor to preserve it.
Proving the Earth is flat is not one of the stated goals of the Artemis program which is to establish a permanent base on the moon to prepare for deep space exploration.
It's kind of wild how every generation gets its own "Blue Marble" moment. Technically we've seen Earth from space a million times by now, but every new human perspective still hits differently
The exif includes time, but not time zone. They are not quite at the moon, and Lunar Time is under active development but not official. Also clocks tick slower under the moon's weaker gravity. (Or is it faster?)
I think the clocks on board Orion are set to Houston time, which would be 5 hours behind UTC (because of Daylight Saving). But I'm not sure. I would expect the EXIF time to be in whatever time zone the spacecraft's clocks are set to.
> clocks tick slower under the moon's weaker gravity. (Or is it faster?)
Compared to clocks at rest on Earth, clocks on board Orion right now are ticking faster, because it's at a high enough altitude above the Earth that the faster ticking due to higher altitude outweighs the slower ticking due to speed relative to the Earth.
That will be true for most of the mission. For clocks in orbit about the Earth, the "breakeven point" where the altitude effect and the speed effect cancel out and the clock ticks at the same rate as an Earth clock is at, IIRC, about 1.5 Earth radii. So clocks on the ISS, for example, tick slower than Earth clocks; but clocks on the GPS satellites (orbiting at 4.2 Earth radii) tick faster (and there is an adjustment made for this on each satellite so that the time signals they send out match Earth clock rates).
For a spacecraft moving at escape velocity, which is going to be roughly true for Orion all the way until splashdown, I think the "breakeven point" is higher, at a little over 2 Earth radii. Orion will reach that point on the way back a few hours before splashdown, I think.
The Moon's gravity well is too shallow to make an appreciable difference in any of these calculations.
I should emphasize that all these tick rate effects are tiny, on the order of one part in a billion to one part in a hundred billion. Even when you add up the difference over the entire mission, it's still only on the order of hundreds of microseconds (i.e., the astronauts end up aging a few hundred microseconds more than people who stayed on Earth).
> So clocks on the ISS, for example, tick slower than Earth clocks; but clocks on the GPS satellites (orbiting at 4.2 Earth radii) tick faster (and there is an adjustment made for this on each satellite so that the time signals they send out match Earth clock rates)
I'm curious, and hope you or somebody else might be able to answer this: is it a single adjustment for each thing, where they just set it to always adjust by X ratio, or does it vary (enough to matter) as it orbits, such that the adjustment needs to be constantly varying slightly?
The exact difference in clock rates is not constant, because the orbits are not perfectly circular and the Earth is not a perfect sphere. So both the altitude and speed of the satellite, and the Earth's gravitational potential, are varying with time, and that means the clock adjustments will vary with time as well.
For the GPS satellites, their time signals are constantly compared with ground clocks, and adjustment signals are sent up to the satellites as needed to keep their clock corrections in sync with ground clocks.
I'm not sure what, if any, adjustments are made to clocks on the ISS, or how they're done.
Thanks! I figured the orbital paths not being exact circles meant they'd be slight variance in the difference, just wasn't sure if it was enough to matter or if they could treat it as if it was exactly the same all the way around without it mattering.
It really is crazy when you think about it, we're capable of taking a picture of the planet we live on from outer space. We take it for granted, that we know what it all looks like. I often find myself wondering how ancient peoples before us would react to something like this
Especially if they knew the sad state of the world whence the rocket was fired from, almost as a distraction of the decay of modern society mankind faces because of their fancy tech and the madmen it enables. I used to be fan of all space tech related stuff, but to me it has lost a lot of its shine. The people of old may say "hey, it is just like Easter island, except their monuments are dedicated to the God of Tech".
"It is the first time since 1972 that humans have travelled outside of the Earth's orbit." But they're not tho (Earth's gravitational dominance extends 4x the distance to the moon)
> It is the first time since 1972 that humans have travelled outside of the Earth's orbit.
They mean outside of low Earth orbit (which basically means further away than the ISS). The phrasing is not ideal.
> Earth's gravitational dominance extends 4x the distance to the moon
"Earth's gravitational dominance" is not a single thing; it depends on what kind of "dominance" you're talking about.
For example, even though the Moon is usually described as being in orbit about the Earth, its orbit is always concave towards the Sun. In other words, its net gravitational acceleration is always towards the Sun--even when the Earth is on the other side of it from the Sun. So by this criterion it's not in orbit about the Earth, it's in orbit about the Sun, doing a complicated do-si-do with the Earth, also in orbit about the Sun.
I'm not sure what definition of "dominance" you're using that extends the Earth's "dominance" to 4 times the distance of the Moon.
This video explains what you’re talking about re the moons orbit always curving toward the sun, and also mentions Earths gravitational dominance.
It’s about the suns gravitational pull on the moon dominating over the Earths gravitational pull on the moon, but that due to the centrifugal force (there isn’t one, so conservation of angular momentum) the Earth's gravitational pull dominates.
The statement I made about acceleration due to gravity was with reference to an inertial frame centered on the Sun, in which there is no centrifugal force. The video you reference takes that viewpoint during its first part.
The claim about centrifugal force refers to the Hill sphere, which is a different notion of "gravitational dominance". The basic idea behind that is that, while the Sun's force on the Moon is greater than the Earth's, it varies in space, in the region where the Earth and Moon are orbiting, much less than the Earth's does. So we can "subtract out" the Sun's gravitational force, so to speak, since we can approximate it as constant in the region we're interested in.
The video, however, bungles this somewhat, because its claim about "centrifugal force" is made in a frame which is centered on the Sun--but rotating at the same rate the Earth revolves around the Sun. But nobody actually uses such a frame! Doing that would be silly. The natural frame for us on Earth to use if we "subtract out" the Sun's gravitational force to analyze the Earth-Moon motion is a frame centered on the Earth.
In this frame, we can say that the Moon orbits the Earth, not because there is some "centrifugal force" canceling out the Sun's force, but because we've subtracted out the Sun's force by centering our frame on the Earth. Or, to put it another way, we're treating the whole Earth-Moon system as freely falling in the Sun's gravitational field, and as long as the Sun's field is, to a good enough approximation, constant in the region we're interested in, we can simply ignore the Sun's gravitational force. (This viewpoint is much more natural in General Relativity, where "gravity" is not a force at all to begin with.) Such a frame is called an "Earth-Centered Inertial" frame, and it's the frame that's being used, for example, to manage the Artemis II spaceflight.
But one could imagine, as a failsafe, arranging things so that Integrity was in fact still in orbit around the Earth, as a sort of "backup" in the event that they somehow missed the moon's slingshot effect.
I know some MAGAs. I promise you they believe it 100%. They often talk of ice walls and one asked me if the Artemis mission would "break through the firmament"?
There is a huge side of TikTok and Reels that most of us here would never find on our feeds which is dedicated to insane conspiracy theories and constitutes a large amount of the media that MAGAs etc consume.
Maybe I'm just a dumb optimist, but I've always assumed that the flat earthers started out as an enteraining debate club intentionally trying to prove something impossible just for the challenge, which got overtaken by a tiny number of vocal idiots. I have heard they largely have moved on to Qanon, which tracks.
The initial modern flat earth movement was absolutely trolling, no doubt about it. But as the myth grew, enough grifters and actual idiots glomed onto the idea that it became what it originally mocked. Poe's law and all that.
Similar to the "I fell in love with an AI!" folks, it's largely undercover salesmen hawking their goods to the gullible.
This photo could be easily faked. I don't believe the Earth is flat, but I also don't think everybody on the planet should be 100% on one side of a discussion. Even if flat-earthers are kinda dumb, I think it's worse to force everyone into intellectual submission just because you're "right".
Even if clearly one side is correct without any doubt whatsoever, beyond any question? Such as 2+2=4 -- we should accept a situation where some people insist this is not true? It seems irrational.
>I think it's worse to force everyone into intellectual submission just because you're "right".
I think it's worse to consider the acceptance of reality as being "forced into intellectual submission" and to use scare quotes around "right."
There are discussions that everyone on the planet should be 100% on one side of and this is one of them. It is literally just wasting everyone's time to entertain the premise that opinions to the contrary hold any value.
It’s a BBC journalistic standards thing; the BBC doesn’t want to express an opinion about the image, they are relaying that as a quote from someone about the image. The word “spectacular” is attributed to NASA in the article.
> Surely our camera gear is exponentially better now
They are better, but not exponentially. You can't beat physics, film cameras can still compete in terms of dynamic range and resolution, the optical elements haven't changed that much. The 1972 photo was taken on medium format film, which is twice the size of the sensor area in the modern one, which means more photons and less noise. The recent image was take at a really high ISO, which adds to the noisiness.
This picture wasn't taken from far away, but I thought about that quote from Carl Sagan -
Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.
One was taken during daylight on film, which needs to be processed and scanned, the other one was taken at high ISO during night time on a digital camera.
So much interpretation is done on colour on each step of the way that it's not surprising the colours are looking different.
The comparison pictures look like there is more dust in the air today. They don't explain this effect, so I assume it is related to time of day the photo was taken, or camera settings, not actual dust accumulation compared to 1972. However, the direct comparison gives the impression they want people to interpret like the air is getting dirtier?
Yes, I was also confused when I first saw it – how could the aurora be visible?! The bright sliver of atmosphere in the lower right is, of course, backlit by the sun which is itself eclipsed by Earth. It's the near-full moon that provides most of the illumination here. Besides both auroral rings you can also see airglow, city lights, and lightning flashes, it's a marvellous photo.
But why not film everything like skydivers do in 8K 120fps from every angle and live stream it? After all, it is 2026...and near-Earth missions like the Moon can now support hundreds of Mbps (even approaching Gbps with laser communication). In the age of live streaming, wasn't this taken into account? All we got is a choppy 480p video feed, if that.
Why didn't NASA or the news agencies rotate the image so North is up? and slightly to the right. That would make Africa instantly recognizable as that's how maps are imprinted in our brains.
There is no "up" in space, so that wouldn't be editing the image I feel. The camera just happened to be oriented "upside down".
I was thinking the same thing, but then I decided to embrace the frustration of the image. It's reminding us that the pictures we have in our heads are kind of fragile. They don't prepare us for a live encounter with Earth from some random angle in space.
I personally prefer to view it in the same orientation the photographer saw it in their viewfinder. Makes me feel more like I’m inside the vessle looking at the planet.
2D midbrains: "It's Africa and Spain, I can tell you because of my superior knowledge of geography! Are you impressed yet"
3D minds of men: "Godspeed you brave soldiers"
4D Galaxy brains: "Israel did 911, all this space shit is a front for making bombs and rockets, nobody knows where we came from or what happens when we die"
I often think about what an amazing time it is to be alive and how amazing all the tech we have at our fingertips is.
But I am also incredibly saddened by the fact that I was probably born just shy of routine space travel.
I can not even imagine how amazing it would be to look down on earth and see it in its entirety. Hopefully my kids or my grandkids will be able to achieve my dream and do exactly that.
A beautiful reminder of what's possible with photography when you're using more than a comparatively crappy iPhone Pro Max camera. (Oh and taking the shot from Outer Space.)
That picture of the "dark" Earth is most fascinating because everyone has seen a million images of Earth before, but how many have seen it in this view. The image by itself says a little about the Earths place in the planetary system.
Come on flat-earthers. I know you are out there. Lets hear your crazy rant about how this is a fisheye lens on a weather balloon or a webcam atop the eiffel tower. Why can't we see the poles? And is that an ice wall on poking up in the lower-right quadrant of the disk?
There is no point engaging in any way with people who believe in such "theories". They are like trolls, the only way to deal with them is not at all. Don't engage, don't disagree, just nothing, total silence. One can choose to be a wilful edit and waste your life and time on complete bullshit, but the rest of us should just ignore those people completely.
Ya, but eventually they all wind up wearing furs and carrying spears as they storm the gates of some government building. Its all good fun until people start to die. We laugh as soveriegn citizens are yanked from thier cars. Harder to watch are the vids of them pulling guns on police.
Conspiracy theorists need to be kept in check. Disengagment is easy but it doesnt help.
Flat Earth is a distraction or a way to ridicule any counter-narrative to anything scientific.
When a cosmologist says that a planet nobody can see exists and is made of x% helium and is y light years away etc etc with absolute certainty despite nobody being able to go there and witness any of it (look how wrong they were about Pluto’s appearance), then you can always just say “what are you a Flat Earther” and easily discredit any doubt I have in these extraordinary claims with underwhelming evidence.
Any idea you want the public to oppose, you can create and market an adjacent thing, like Trump. You can throw all the ideas you want to oppose in the Trump bucket and if anyone supports it it’s probably because they’re a Trump supporter right?
See you’re very very easily programmed, like clockwork.
> It is taught that the scientific method provides evidence, not certainty, in middle school science curriculum.
FWIW, this fact isn't taught properly or normies are somehow unable to process it.
There's this popular dismissal of tech people, saying that "they think in 0s and 1s, but world is shades of gray", but in reality, it's almost everyone else that thinks in 0s and 1s - STEM people and people in/into similar fields (like medicine) are usually forced to understand nuance due to nature of their interests/occupation, but everyone else seems to operate in purely binary mode, and what's worse, whether something is true and false isn't even correlated much with objective reality, and mostly with one's personal feelings about how things should be.
(Now, to be an equal opportunity cynic, in my experience, the concept of categories and taxonomies being arbitrary - invented and assigned by people, and judged by their usefulness, as opposed to being inherent facts of nature that are discovered - seems to be hard for even STEM people to process, for some reason, at least based on my observations and the number of conversations I had about this with all kinds of people.)
I do not know what you mean about "how wrong they were about Pluto’s appearance".
Since when I was very young and until now the amount of information about Pluto has continuously increased, so now we know much more about it.
For example now we know that Pluto is practically a double planet, having a relatively very large satellite. This was not known when I was a child, e.g. at the time of the first NASA Moon missions.
However, I do not remember anything wrong. Many things that have been learned recently were previously unknown, not wrong.
If you refer to the fact that Pluto was reclassified as a dwarf planet, that is also a case of information previously unknown, not wrong.
This planetary reclassification was not the first.
When Ceres was discovered in 1801, it was considered the 7th planet, after the 5 planets known in antiquity and Uranus that was discovered a few years earlier. (The chemical elements uranium and cerium, which were discovered soon after the planets, were named so after the new planets, as their discovery impressed a lot the people of those times.)
However, soon after Ceres a great number of other bodies were discovered in the same region and it was understood that Ceres is not a single planet, but a member of the asteroid belt.
Exactly the same thing happened with Pluto, but because of its distance, more years have passed until a great number of bodies have been discovered beyond Neptune and it became understood that Pluto is just one of them, i.e. a member of the Kuiper belt, so it was reclassified, exactly like Ceres.
> ...discredit any doubt I have in these extraordinary claims with underwhelming evidence.
Something unfortunate about our media environment is that science news is a dumbed down summary of a dumbed down summary of a dumbed down summary. These issues you're flagging, a lack of evidence and overstated certainty - they're an artifact of the reporting process. If you work your way back to the original sources, there will be a heck of a lot of evidence and it will carry error bars (so the certainty is precisely & appropriately stated). There's bad or even fraudulent papers out there but there's a huge amount of good science being done by honest researchers who are just as concerned as you are about the quality of the evidence and the degree of certainty.
Eg, there really is a compelling explanation of how we can know the composition of a gas giant light-years away, and it isn't invented out of thin air, it's been 100+ year process of understanding spectroscopy and cosmology, building better telescopes, etc. It's the culmination of generations of scientists pushing the field forward millimeter by millimeter.
The only real difference between the "spaceflight" in the 1960's and today is that these pictures don't need to be hand painted - you can render them in Blender in a single day.
But yeah, sure. With the amount of fake stuff on the internet including AI image generation, we're expected to believe that the US government dumped billions of dollars into going to space when they could give the appearance of doing so for a few bucks in nano banana credits? Hah.
They couldn't do that for "a few bucks of nano banana credits" though. You could generate the imagery but that's only one line of evidence. A launch is easily detectable through multiple signals.
Why would Russia and China and any other country with any degree of astronomic capability that the US has an adversarial relationship with just let them get away with lying to the world? Why wouldn't they take the opportunity to humiliate the US by revealing that no launch happened and that they cannot detect the spacecraft?
How would they prove that no launch happened? There isn't conclusive evidence of an absence of launch, and if there were it would be accused as being fake and a ploy from American enemies to discredit them.
> There isn't conclusive evidence of an absence of launch, ...
A launch is detectable seismically, visually, on radar, etc. There's a lot of investment in being able to detect launches (to detect the launch of nuclear weapons). It would be screamingly obvious if the launch was fake. It would absolutely be conclusive if there were no seismic activity, no radar return, they couldn't detect the spacecraft presently, etc. At least for a definition of "conclusive" that can be operationalized - conclusiveness is a judgement call about when evidence is sufficient and not reaching some theoretical 100% certainty. Which can't possibly be reached for any claim for the reason you outlined; you can always invent some negative counterclaim that can't be entirely dismissed, even for claims like "the sky is blue".
It's also pretty easy to find people who were physically there to witness the launch. This wasn't a secret bunker or a barge in the middle of the ocean. It was in Florida in the late afternoon.
> ...it would be accused as being fake and a ploy from American enemies to discredit them.
Hundreds of thousands of people around the world have access to this data. Astronomers, geologists, petroleum engineers, backyard amateurs. The conspirators could muddy the waters but they couldn't ultimately prevail. It is many orders of magnitude easier to go to the moon than to convincingly fake it.
Your comment history suggests you're in the US, so you should be pleased to learn that you weren't included. The visible landmass is northern Africa, with a smidge of the Iberian Peninsula visible.
Oh, good point. I missed South America under the cloud cover. I guess the Eastern edge of the US would indeed be visible as a highly distorted smudge on the edge of the visible surface.
Thank you. I have having trouble making sense of the orientation. My first thought was misshapen Australia, but where Spain nears Africa is much different than Australia and Tasmania. Also, they forgot New Zealand... while common for maps, I would expect it to show up in a photo.
I don't understand why media, such as BBC, keep uploading heavily compressed versions of photos that could be beautiful. The original has grain, sure but that's not a problem. The BBC version is horrific. Are they trying to save on bandwidth in 2026?
It's highly reasonable for them to limit image size/quality to whatever looks fine to 98% of their readers. They store and serve an absolute ton of ever-changing content to browsers/apps; The very small (and likely revenue-negative) contingent of highly motivated people can find the originals if the images are especially noteworthy like these.
"I cannot immediately find a photo on a website, therefore I will denigrate the agency that sent people into OUTER SPACE to make these incredible images possible."
Looking at the EXIF (with exiftool) for the image uploaded by NASA (https://www.nasa.gov/wp-content/uploads/2026/04/art002e00019...), apparently this was taken by a Nikon D5 with an AF-S Zoom-Nikkor 14-24mm f/2.8G ED and developed with Lightroom. It also seems like very little was done in Lightroom. Amazing... I dumped the whole EXIF here: https://gist.github.com/umgefahren/a6f555e6588a98adb74eed79d...
Yes, the D5s are the 'official' Handheld Universal Lunar Cameras (HULCs), but (a?) Z9 also got on-board at the 'last minute' (which means two years ago):
* https://petapixel.com/2026/04/02/a-nikon-z9-made-it-aboard-t...
They have a thermal blanket for exterior work:

* Various stories with the "Artemis" tag: https://petapixel.com/tag/artemis/
The D5 has been used on the ISS, including EVAs, since 2017, so they're a known quantity:

The Mercury and Apollo missions used Hasselblad 500-series-based cameras (modified):
* https://www.hasselblad.com/about/history/hasselblad-in-space...
the morning after the launch i just randomly went onto their livestream and one of the astronauts was asking mission control for help on also using the gopros and iPhone cameras. i guess they have some. and he was struggling at getting a properly exposed photo with those. he said they were coming out super over exposed. but the D5 was working nominally. mission control said they'd get back to them about ideas on adjusting the gopros and iPhones. but it was funny to hear they're trying "new" tech and struggling with it up in space, and that 2005 D5 is still the champ :)
The SLR-like cameras have a bunch of manual modes so you can 'force' them to get something captured, and you can then perhaps 'fix it in post'.
Modern tech allows more people to capture more things more easily, but when the automation fails there aren't really many manual modes to fall back on.

he was struggling at getting a properly exposed photo with those. he said they were coming out super over exposed.
This is exactly what newbies experience when trying to photograph the moon from Earth. It's not intuitively obvious, but the light coming off the moon is essentially full-daylight bright. But the moon is small against a very black background, and depending on how the auto-exposure is operating, this often leads to guessing that the scene as a whole needs a lot more exposure.
I imagine that trying to photograph the Earth when a significant part of what's in view is experiencing daytime, is very much the same thing.
You have to wonder how unserious this can get. Given the unimaginable cost of this mission, they are faffing around as your typical aunt with Windows Home laptops and iPhones? Seriously?
I'll echo that "sheesh" in the other comment, too. They're so unserious compared to those super serious Apollo guys[1], right? After all, the Apollo folk never would've smuggled contraband for fun on the Moon[2]!

Sheesh, let the lab mice have a breather. Want them to solve physics during the trip?
as a Hassie lover it made me a bit sad that they went with a D5 but hey, who cares about the camera, the picture was worth a billion bucks and it delivered.
It's so refreshing to be mesmorised by a picture in the age of shorts and reels.
Before Lightroom it might have looked closer to this: https://images-assets.nasa.gov/image/art002e000193/art002e00...
From the EXIF we can infer that every setting was left at the default. No exposure comp, no contrast, no HSL, no lens correction and a linear tone curve. Just the default Adobe Color profile at 5400K.
The photograph appears to show nightime on Earth with just a sliver of daytime. Beyond cities in Iberia and along the coast of Africa, most of what we can see would be reflected light from the Moon? We are just past full moon on April 1.
1/4 exposure time so 250 ms of light. the light is coming from all the light sources in the universe, plus the moon, plus the sun's rays refracting through the atmosphere which happens even at night.
The natural blue light is coming from the oxygen in the atmosphere but it's so overwhelming in that spot that it turns the light pure white. The red/orangish is coming from particulates and the green/red from aurora. My favorite part I think is the very bottom where you can see the blue light taper off and not overwhelm the camera sensor and you can see the aurora with it. I love this photo so much.
Probably my favorite photo ever now.
> the light is coming from all the light sources in the universe, plus the moon
And all the others are negligible by many orders of magnitude compared to the moon. So it's really just the moon as far as this photo is concerned (except for the small sliver that's still illuminated by sunlight, including refracted sunlight).
> the light is coming from all the light sources in the universe, plus the moon
This is true for every photo ever taken
so the atmosphere acts as giant lamp lit from behind by Moon? never thought of it that way
> the light is coming from all the light sources in the universe,
That's highly incorrect. I have many lightsources that aren't contributing to any photons in that picture. For example my refrigerator light.
I turn off my refrigerator light after I close the door by reaching in and pushing the button. Don’t you?
> Beyond cities in Iberia and along the coast of Africa, most of what we can see would be reflected light from the Moon?
Yes, exactly.
That's what the caption the article above says
Maybe it’s because I (like many) have experienced taking pictures at night and seeing the grainy result that _this_ image struck me as incredibly realistic.
Almost like I ran the grainy-to-real conversion in my mind and I felt like I was imagining seeing this in person. Beautiful image!
Might I ask, what was your path to finding this image?
https://www.nasa.gov/gallery/journey-to-the-moon/
Thanks so much. Sending this link to my nerdy nephews immediately.
But that one (art002e000193~large.jpg) is only 287kB. The Lightroom-processed one is 6.2MB. I would expect original to be heavier.
The Lightroom one was processed from raw. Also, by brightening it a lot, the noisy high-ISO grain becomes more apparent. Noise is famously incompressible, so it leads to a much larger file size.
Brightening the image may make the iso noise easier to see, but it doesn't create it.
But lossy-codecs job is to utilize psychovisual tricks to discard as much high-frequency information as possible, whilst remaining similar visual effects. If you increase the brightness in RAW and then re-encode the JPEG - more noise is being pulled up in the visual spectrum, therefor less of that information (filesize) is discarded.
For example, if you render Gaussian noise in photopea and export as JPEG 100% quality, it has 9.2MB. If you reduce the exposure by -2 it goes down to 7.8MB. That's partially because more parts of the noise are effectively black pixels, but also I believe because of the earlier mentioned effect.
Noise that's easier to see will not be compressed away by the JPEG compression. JPEG is basically just DCT + thresholding. Any higher amplitude noise is going to stay and increase the final file size.
Also, pulling more data from your 14 bit or 16 bit raws results in more noise in the end compared to the straight-out-of-camera 8 bit JPEGs.
It's not lossless
The resolutions are different, 1920x1280 vs. 5568x3712.
Also possibly different JPEG quality settings.
Could be the thumbnail / preview image generated alongside the raw
It's beautiful as these all are, that one is probably my favorite. And as somebody else said it kind of feels more real seeing the grain like that. It's just beautiful. A side we never see quite like this.
I'd have probably shot it wide open at f/2.8 rather than cranking the ISO up to 51200. Incredibly impressed at the steady hands for a sharp image at 1/4 s shutter speed though! Maybe they just let the camera float in space with the mirror up, triggering it remotely.
> I'd have probably shot it wide open at f/2.8 rather than cranking the ISO up to 51200.
One of the reasons the D5 supposedly was chosen was because of its high dynamic and good low light performance. It can go up to ISO 3,280,000:
* https://en.wikipedia.org/wiki/Nikon_D5
The D5 has been used on the ISS, including EVAs, since 2017, so is a known quantity:
* https://en.wikipedia.org/wiki/List_of_cameras_on_the_Interna...
The good low light performance was amazing for its time (10 years ago), and it still holds up decently today. But let's not kid ourselves -- it has been clearly surpassed by modern backside illuminated CMOS sensors like the one on the Z9.
EDIT: sorry, it seems I'm wrong. I just checked https://www.photonstophotos.net/Charts/PDR.htm and while the Z9 has the clear edge with 2 more stops of dynamic range at low ISO, the D5 actually pulls ahead at high ISO. Perhaps the technological improvements haven't been that much for the shot-noise dominated regime.
Sure, but D5s were also doing EVAs for many years and much more of a know quantity in space.
Was hoping to hear from the person at NASA who made the choice and why.
You can get a D5 on amazon.com. It would be amazing if one of the astronauts did a review explaining how it performs in space.
Oh man. "Rolled with the D5 on my recent trip around the moon, decent performance, very light and easy to hold in zero gravity".
f/8 and be there?
You might misunderstand how ISO works on digital cameras. (I did.)
https://www.youtube.com/watch?v=ZWSvHBG7X0w
Good grief, that video suffers the YouTube-ism of "ramble on about how you don't understand X" for way too long.
Video alleges people think ISO makes the sensor "more sensitive or less sensitive". (I … don't think this is common? But IDK, maybe this is my feldspar.)
(The video also quibbles that it is "ISO setting" not "ISO" … while showing shots of cameras which call it "ISO", seemingly believing that some of us believe ISO is film speed, in a digital camera?)
Anyways, the video wants you to know that it is sensor gain. And, importantly, according to the video, analog gain, not digital gain.¹ I don't know that the video does a great job of saying it, but basically, I think their argument is that you want to maximize usage of the bits once the signal is digitized. Simplistically, if the image is dark & all values are [0, 127], you're just wasting a bit.
You would want to avoid clipping the signal, so not too bright, either. Turn your zebras on. (I don't think the video ever mentions zebras, and clipping only indirectly.)
The video does say "do ISO last" which I think is a good guideline. Easier said than done while shooting, though.
… also while fact checking this comment, I stumbled across Canon's KB stating to use as low an ISO as possible, which the video rails against. They should talk to Canon, I guess?
¹with the caveat that sometimes there is digital gain too; the video notes this a bit towards the end.
ISO changes the analog gain and in a way yes, it does make it more sensitive to a certain range of brightness.
This is because the ADC (analog to digital converter) right after can only handle so many bits of data (like 12-16ish in consumer cameras). You want to “center” the data “spread” so when the “ends” get cut off, it’s not so bad. Adjusting the ISO moves this spread around. In addition, even if you had an infinite bitrate ADC, noise gets added between the gain circuit and the ADC so you want to raise the base signal above the “noise floor” before it gets to the ADC.
Gain is not great — it amplifies noise too. You want as low ISO as possible (lowest gain), but the goal is not actually to lower gain; your goal is to change the environment so you can use a lower gain. If you have the choice between keeping the lights off and using higher ISO versus turning on the lights and using a lower ISO, the latter will always have less noise.
Most photo cameras have one gain circuit that has to cover both dark and light scenes. Some cameras like a Sony FX line actually have two gain circuits connected to each photosite and you can choose, with one gain circuit optimized for darker scenes and the other optimized for brighter scenes. ARRI digital cinema line cameras have both and both are actually running at the same time (!).
> your goal is to change the environment
...or integration time.
> The video does say "do ISO last" which I think is a good guideline. Easier said than done while shooting, though.
> … also while fact checking this comment, I stumbled across Canon's KB stating to use as low an ISO as possible, which the video rails against. They should talk to Canon, I guess?
Isn't ISO last the same as setting it as low as possible? Obviously it's always set to something, so I thought 'doing it last' means start with it low, set exposure & shutter, increase as necessary?
(Shutter speed being dictated by subject and availability of tripod, essentially it's just exposure & ISO which becomes about how much light there is and how it's distributed, I suppose.)
I'm not really into photography though, so perhaps that's all nonsense/misunderstanding.
Sounds like you'll be spending your day making a better video! :-)
i think we need to differentiate between raw or derivative format. canon KB might cater to wider audience thus the latter
Wide open generally sacrifices lens sharpness.
Sure, but less grain is often worth it. There's a reason why fast lenses exist. The high quality lens being used here can probably still resolve 20 MP adequately even wide open.
I had that lens. It’s soft as fuck around the edges open.
Peak sharpness is about f/8. They should have had the D5 on aperture priority auto iso, pushed the exposure comp either way and then just fired at f/8 and let the camera make the decisions.
But they are astronauts not photographers :)
The modern Z lenses are far better and sharper open but much larger generally.
It was shot at f/4, so opening up 1 stop to f/2.8 would only reduce the ISO to 25600
I would imagine since they are not circling the earth, that there will be pull of gravity and the camera would start to move relative to the spacecraft. But may not fast enough for a short exposure
Once you are out of the atmosphere and turn off your thrusters, you are on "fee fall" and the gravity on the camera, you and the spaceship produce the same acceleration and they cancel and it looks exactly like "zero gravity". It doesn't matter if you are in orbit around the Earth, going to the Moon.
Actually not quite correct. The camera and spaceship will generally have different starting positions of their center of gravity but the same starting velocity, leading them to drift apart.
The only real relevant thing for the photograph is rotation though as long as the camera doesn’t float in front of the window frame, and airflow is probably much more relevant for both points than gravity.
The gravity of the Earth (and moon, and everything else) is uniform (i.e. no gradient) on the scale of things the size of that capsule at the distance that capsule is from them, on the order of time of the exposure of that photograph. So the gravity (from any source) will pull on the spacecraft and on the camera in the same fashion.
To fully answer the question, the moon's gravitational gradient does pull on the Earth, the ocean closest to the moon, and the ocean furthest from the moon differently. But those are objects separated by thousands of kilometers, having hours of gravitational influence acting upon them.
They’re not circling the Earth, but they’re still orbiting it. Their orbit is highly eccentric, and will be near the Moon at apogee.
They're in space so they only sort of need to hold the camera.
Or maybe press the timer and let it float...
Bad idea, shutter speed was 1/4 apparently (https://news.ycombinator.com/item?id=47632457), even the small rotational inertia everything in zero gravity gets from a human "dropping" it would probably be enough to be annoying, you'd get a better shot holding it.
or sticky-tape it to the window.
d5 has an actual shutter yeah? not mirrorless? I think the shutter moving will spin the camera.
I haven’t looked at the manual but it likely has the ability to flip and keep the mirror up for direct capture on the sensor without the mirror flipping up and down between exposures.
If you think they only took one shot, you're not a digital photographer)
In this special situation you get as many as you can a few dozen at least. Then only publish the one that looks the best. If it's f4 then f4 worked best.
The EXIF data says that the picture was taken with the flash off!
How did they get the Earth to light up when it is obviously dark outside? Is this fake?
Possibly you're just joking, but it's pretty obvious that the flash would not appreciably illuminate the entire earth.
Obviously. It was a joke.
Nice. It would've been cool to see what the location information in the EXIF looked like, if it were there.
The D5 doesn't have built in GPS, and adding it requires an attachment. I don't know if the smartphone app works on that model, but it is from the same year as my D5600 which does support it. The app provides GPS but also drains the battery fast. I turned airplane mode on after the first dead battery.
GPS might work out there though: https://www.nasa.gov/directorates/somd/space-communications-...
If you use a regular smartphone in space (or technically in orbit for this argument), it’s probably not going to get a fix because GPS receivers are required to stop locating when reaching some speed to not be export controlled. And that speed is picked so people don’t build missiles, orbital speed will be higher.

It's fun to think about tile dilation per the exif captured Create Date: "2026:04:03 00:27:39.26". I know it's negligible over the trip, but when they took it, was their time really "2026:04:03 00:27:39.25"?
While the D5 is a great camera it's ~10 years old. Wonder why they didn't go for the Z9 which is its modern mirrorless equivalent.
"The Nikon D5 remains the camera of choice for the Artemis II mission and will be assigned primary photographic duties. It is a proven, highly-tested camera that the Artemis II team knows will excel in the high-radiation environment of space. However, as Artemis II Commander Reid Wiseman explained ahead of yesterday’s launch, he successfully fought to have a single Nikon Z9 added to Artemis II’s manifest."
https://petapixel.com/2026/04/02/a-nikon-z9-made-it-aboard-t...
There are more interesting details in the PetaPixel article, such as: "'That’s the camera that they’ll be using, the crew will be using on Artemis III plus, so we were fighting really hard to get that on the vehicle to test out in a high-radiation environment in deep space,' Wiseman said."

But yeah the grainy photo of the Earth with the D5 at ISO 51200 shows the shortcomings of the ancient DSLR. Still, great shot.
I'd argue the D4s and D5 may be some of the best high ISO cameras I'm aware of maybe surpassed by that one canon video camera that can seemingly see in the dark (sorry I'm mobile) and the D3s. I think the lower numbers produce nicer looking max ISO noise but that's all preference. Sony has the A7s as well but as with some of these the overall resolution isn't extreme.
How does the age of the camera influence physics? The only thing that really helps would be increasing the aperture.
Lower noise sensors and better image stabilization for longer exposures
The D5 has flight heritage to use the industry term.
From what I recall reading its more or less, "we have established and validated processes for using the D5." Its less about getting the best possible photo, more about making sure what they do take looks fine and doesnt waste a ton of time.
It might be the newest thing on the ship.
Zero point in measuring camera sizes (or other sizes haha) when JWST is floating there.
Government budgets man…
250 ms f/4 ISO 512000 in case anyone was wondering. I wonder if they applied any denoise, it looks great for such high ISO
Wild. I saw a quick glance and assumed the Z9 but the D5 is near the peak of the DSLR world so I guess.
The ISO 51200 would certainly explain the grain when viewing the image at 1:1 scale.
Any GPS data? I wonder if it would pick anything up. Altitude reading would be interesting!

Thanks! This was my first question.
It also seems like very little was done in Lightroom.
This is consistent with good photographic technique that prioritizes "getting it right in the camera."
...
My only curiosity, and yeah I know orders of significance etc...
Buuuuut I wonder why they didn't consider a Z5[0][1] and the Z mount 14-24, or the Z5 with an adapter for the F mount 14-24....
There's at least a pound of weight savings on the table.
Specifically, I wonder if it's a fun reason? i.e. it would be interesting if there was a technical reason like 'IBIS fails miserbly' or 'increased sensor resolution adds too much noise' (even at that ISO you gave from the EXIF...)
[0] I'm really more of a Sony person but am thus keenly aware about importance of UX feel, so I tried to keep the question apples to apples here.
Edited to add:
[1] Per [0] I may be stupid in thinking the Z5 is a 'at least minimal' substitute so happy to learn something here.
They have a Z9 on board for radiation testing, but the D5 is the primary body for imaging on this mission IIRC
The D5 has been used on the ISS since 2017, including EVAs:
* https://en.wikipedia.org/wiki/List_of_cameras_on_the_Interna...
The ISS now (also?) has Z9s. So they're both generally known-quantities.
Yeah other folks gave better insight while I was writing my comment, oops...
When you're riding a rocket that weighs 3.5 million pounds...
Mass higher up the rocket costs several multiples more mass in propellant and propellant handling lower in the rocket. And the more deltaV you want the higher the multiplication. (If I remember right some weight issues of some kind on the Apollo capsule and or lander required a common bulk head in the first stage to make up the performance loss!)
However cameras probably fall into the variance in astoraunt weight somewhat.
Is that the Rocket or the Craft+Mission payload?
My understanding is it's on the order of 5-10 pounds of rocket juice to get one pound of something to LEO, thus the question.
At 3.5 mil pounds that has to be the full rocket. But quick [1]googling is giving an even higher total mass number...

I was confused when I first saw this photo, as I don't think I've ever before seen a nightside, moonlit Earth, exposed so that it looks like the dayside at a first glance. I wonder how many casual viewers actually realize it's the night side. A nice demonstration of how moonlight is pretty much exactly like sunlight, just much much dimmer. In particular it has the same color, even though moonlight is often thought of as bluish and sunlight as yellowish!
I've done several shoots lit only by the full moon. Doing long exposure, the images are as you stated not much different than an image taken during the day, except for looking at the sky and seeing stars.
I've also done video shoots with the newer mirrorless cameras and fast lenses shooting wide open again lit with nothing but the full moon. It again looks daylight on the image. As a bit of BTS, I recorded a video of the screen on the camera showing what it was seeing, and then pulled away and reframed to show essentially the same shot as the camera but it's just solid black. One of those videos was fun as we caught a bit of lens flaring from the moon, and you can actually see the details of the surface of the moon in the reflection. It was one of those things I just never considered before as flares coming from lights or the sun are just void of detail.
Thanks. Until you pointed out it's Earth at night, I had no clue what was supposed to be special about this photo (it appeared suspiciously pixelated for something 'high res', and neighbouring pixels seemed to contrast in colour rather than smoothly complementing as most photos do - but I guess that's random patches of city lights being captured by the camera). Cool stuff!
Something I haven't figured out is: what is that yellow/whitish smudge toward the center of the earth? It looks like camera glare or a reflection?
Yeah, it's a reflection from the window, of something inside the ship.
It explains why the image is so grainy. At first I was confused what that stripe to the left and the bottom was. But it’s just the window edge, and the noise isn’t stars.
(To be clear, the bright dots are stars [except the brightest one, in the lower right, is Venus I think], which makes this photo also a great demonstration that of course you can capture stars in space, you just have to expose properly!)
Who said you can't capture stars in space? What do you think the purpose of Hubble, JWST, etc are? There's also plenty of imagery taken from ISS that clearly show stars. I've definitely seen Orion in some of that imagery and it put a different perspective on the size of the constellations when seen from that angle.
I referred to the common question (or accusation) of why there are no stars in, say, the Apollo photos taken on the moon. The answer is, of course, that you can't see stars if you're exposing for something bright and sunlit, like the day side of Earth, or the lunar surface.
Of course. But they are not visible in the Chang’e photos on the dark side either. I think in the interview of the astronauts following the first Apollo Mission, a reporter asked for a confirmation that the stars were not visible because of “the glare” (an interesting question in itself). The explanation given was that the stars were not visible with the eye, but were visible with “the optics“.
Photos from the moon landings don't have stars in them, because they are exposed for full daylight on the moon.
I’m assuming the people who complain that there aren’t stars are the “moon landing faked” crowd… it’s hilarious to me that they think this vast conspiracy came together to fake that whole thing, and that they literally forgot to put a bunch of tiny 25-cent flashlight bulbs up poking through the black backdrop on the sound stage. Like, no one thought about the stars, or they couldn’t figure out how to do those “special effects” and just prayed no one would spot the error.
Just answered my own question to my satisfaction; they are stars.
The same specs, which match star charts, show up in two images taken a few moments apart at different exposures (links were given down-thread).
How do you know that they're stars? I believe they probably are stars as well (by visual comparison with a star chart, suitably rotated), but I've found no source for either claim.
I did find multiple sources, including TFA, for the brightest being Venus.
They're much brighter than the noise floor. Photographic noise doesn't really have such outliers.
Why would you think they are not stars? Not really sure the confusion on the matter. Are we leaning towards this being shot from a soundstage?
Well one of them is obviously Venus. How did you determine the others weren't stars?
I’m talking about the grainy noise over all the black parts (actually over the Earth disk as well), including beyond the window edge. The window edge itself looks like a denser and brighter stripe of stars.
Zoom into this higher-resolution version: https://www.nasa.gov/wp-content/uploads/2026/04/art002e00019...
Yep, that's definitely noise.
What does it look like to human eyes? Is there enough light for a person up there to see colour, or would it look like black and white (like a moonlit scene on the ground).
No color, I’m pretty sure.
The camera is compensating for extremely low light, so you end up with something that looks closer to a daylight exposure
I know. Apparently this was shot at ISO 51,200.
It’s a remarkable photo. You can see the aurora Australis at the top right of the image (it’s upside down, if there is such a thing - that’s the straits of Gibraltar at the lower left, and the Sahara above it - and the skein of atmosphere wrapping the entire planet. Those look like noctilucent clouds in the north, or possibly more aurora.
It really is gorgeous. You can see both auroral rings, then there's airglow, and city lights around Gibraltar and on the South American coast, and lightning flashes in the storm clouds over the tropics.
Same! I mean the last time we were in space the cameras were ... not this good. I can't wait to see more photos from modern hardware!
> even though moonlight is often thought of as bluish and sunlight as yellowish!
Is that... true? Sunlight is seen as yellow, of course, but the moon is usually thought of as white.
Sunlight is yellowish in atmosphere since some blue's been scattered by the atmosphere[1], but it's white in space.
[1] https://en.wikipedia.org/wiki/Rayleigh_scattering
I don't think that's right. Sunlight is white in the atmosphere too. Scattering causes the sun, not the light, to look yellow, and so sunlight is thought of as yellow.
Scattering doesn’t really make the sun to appear yellow except when it’s low, behind a lot of air. When it’s above 30° or so it just looks blinding, neutral white (or non-blinding neutral white if there’s suitable cloud cover or other filter in front of it). Even though a lot of the blues are scattered around, the sun still looks just white when it’s high in the sky.
But when the sun does look yellow, its light is yellow too, that’s the definition of "looks yellow". And the golden hour paints everything in very iconic yellow-orange hues. The light as integrated over the whole sky is still white (modulo whatever’s scattered back into space), but the light that comes from the direction of the sun is clearly tinted yellow and the light from the rest of the sky is clearly tinted blue.
> But when the sun does look yellow, its light is yellow too, that’s the definition of "looks yellow".
Not quite; the sun is far away and is restricted to a tiny portion of the sky, but its light covers half the earth at a time. It is simultaneously true that the sun looks yellow and that the light we receive from it is white. It isn't the case that objects in direct sunlight are yellowed by that light; the yellow appearance when you look at the sun is something of an illusion.
> Even though a lot of the blues are scattered around, the sun still looks just white when it’s high in the sky.
This isn't true.
That's fair, I was thinking of how night, or twilight, as a whole is associated with cool hues, but it's probably true that moonlight in itself is usually thought of as neutral white.
Moonlight is reflected sunlight.
That's obvious. But the moon is so perfectly neutral gray that the reflected light is essentially the same color as the incident sunlight.

This video explains how ISO is very different to what most people imagine, and how you can use this knowledge to take less noisy photos.
There's something a bit weird having these digital photos and crisp digital audio and video of the astronauts, and seeing pictures of mission control with flat screens after having grown up on grainy analogue video, crackly audio with lots of beeps, and mission control being choc full of CRTs being watch by men in short sleeve shirts with black ties and cigarettes.
I get that feeling, but I think a lot of the "texture" we remember is really just the limitations of the tech at the time
I had a similar thought at first, and then remembered the steady technical progress of the Shuttle era (at least from my recollection).
Pale Blue Dot subtly shaped my perception of Earth.
We are not standing on earth looking up at the stars.
We are being held by earth as we look down into an infinite abyss of death.
Everything we are depends on that fragile bubble holding us.
I love the fact that you can see the aurora at both poles!
I may be mistaken but there's even atmosphere visible - that tiny translucent band on the darker photo

I wish I could see a pic from today with the aurora. I was surprised to see the aurora in northern Europe a couple hours ago, it is very active right now.
Yeah, it is - unfortunately, it is rather cloudy in my area at the moment. Luckily, the weather was better during the 19./20. January event, which I'll carry forever in my heart.
I like the non brightened version, where you can clearly see the light coming from cities. How cool would it be if we saw similar on another planet...
It's humbling to see this image. I can't even begin to imagine what it must feel like to see this from the perspective of those astronauts.

It is funny if you think about it, imagine you arrive on a planet and there is nothing there, now what. Not saying it is not worth doing but it's like other aspects of life, about the journey. But yeah I think we are lucky to have this ability/get outside of our sandbox. Be aware of the bigger picture.
If you are interested in taking similar images, there are several satellites transmitting ‘full disk’ images like this, instead of a camera you need a dish or yagi a sdr and lna. Example satellites are Himawari 8, GOES 18, Fengyun 2H.
And they can be found online pretty easily: https://himawari8.nict.go.jp/.
I remember there's some tools to use the images as desktop backgrounds: https://github.com/boramalper/himawaripy
I remember watching grainy B+W ones in the 80s via a dish. It might have been a slow scan signal back then? It blew my mind watching the Earth live as a disk, seeing the weather in realtime.
This is all we've got. We need to do a better job of preserving it.
Finally: Yes, global warming is real, but the threat is different. I predict that we will far exceed the average increase in global average temperature, but we will survive. Yes, we will survive, but with some "scars".
We have done a lot better with faster and readily perceptible environmental problems.. from air pollution in China to acid rain killing forests and lakes in Europe. So yes, we should celebrate our successes too.
Unfortunately that would affect shareholder value.
One of the objectives of the Artemis missions is to prepare for Mars travel, none of the objectives of Artemis are to view Earth as the only planet we have nor to preserve it.
You must be a capitalist pig with trump delusion, lol! This point of artemis is to prove the earth is flat. the picture proves it! I downvote thee!
Proving the Earth is flat is not one of the stated goals of the Artemis program which is to establish a permanent base on the moon to prepare for deep space exploration.

It's kind of wild how every generation gets its own "Blue Marble" moment. Technically we've seen Earth from space a million times by now, but every new human perspective still hits differently
Fun question: What time was this taken?
The exif includes time, but not time zone. They are not quite at the moon, and Lunar Time is under active development but not official. Also clocks tick slower under the moon's weaker gravity. (Or is it faster?)
Anyway, what time was this taken?
I think the clocks on board Orion are set to Houston time, which would be 5 hours behind UTC (because of Daylight Saving). But I'm not sure. I would expect the EXIF time to be in whatever time zone the spacecraft's clocks are set to.
> clocks tick slower under the moon's weaker gravity. (Or is it faster?)
Compared to clocks at rest on Earth, clocks on board Orion right now are ticking faster, because it's at a high enough altitude above the Earth that the faster ticking due to higher altitude outweighs the slower ticking due to speed relative to the Earth.
That will be true for most of the mission. For clocks in orbit about the Earth, the "breakeven point" where the altitude effect and the speed effect cancel out and the clock ticks at the same rate as an Earth clock is at, IIRC, about 1.5 Earth radii. So clocks on the ISS, for example, tick slower than Earth clocks; but clocks on the GPS satellites (orbiting at 4.2 Earth radii) tick faster (and there is an adjustment made for this on each satellite so that the time signals they send out match Earth clock rates).
For a spacecraft moving at escape velocity, which is going to be roughly true for Orion all the way until splashdown, I think the "breakeven point" is higher, at a little over 2 Earth radii. Orion will reach that point on the way back a few hours before splashdown, I think.
The Moon's gravity well is too shallow to make an appreciable difference in any of these calculations.
I should emphasize that all these tick rate effects are tiny, on the order of one part in a billion to one part in a hundred billion. Even when you add up the difference over the entire mission, it's still only on the order of hundreds of microseconds (i.e., the astronauts end up aging a few hundred microseconds more than people who stayed on Earth).
> So clocks on the ISS, for example, tick slower than Earth clocks; but clocks on the GPS satellites (orbiting at 4.2 Earth radii) tick faster (and there is an adjustment made for this on each satellite so that the time signals they send out match Earth clock rates)
I'm curious, and hope you or somebody else might be able to answer this: is it a single adjustment for each thing, where they just set it to always adjust by X ratio, or does it vary (enough to matter) as it orbits, such that the adjustment needs to be constantly varying slightly?
The exact difference in clock rates is not constant, because the orbits are not perfectly circular and the Earth is not a perfect sphere. So both the altitude and speed of the satellite, and the Earth's gravitational potential, are varying with time, and that means the clock adjustments will vary with time as well.
For the GPS satellites, their time signals are constantly compared with ground clocks, and adjustment signals are sent up to the satellites as needed to keep their clock corrections in sync with ground clocks.
I'm not sure what, if any, adjustments are made to clocks on the ISS, or how they're done.
Thanks! I figured the orbital paths not being exact circles meant they'd be slight variance in the difference, just wasn't sure if it was enough to matter or if they could treat it as if it was exactly the same all the way around without it mattering.

It really is crazy when you think about it, we're capable of taking a picture of the planet we live on from outer space. We take it for granted, that we know what it all looks like. I often find myself wondering how ancient peoples before us would react to something like this
Especially if they knew the sad state of the world whence the rocket was fired from, almost as a distraction of the decay of modern society mankind faces because of their fancy tech and the madmen it enables. I used to be fan of all space tech related stuff, but to me it has lost a lot of its shine. The people of old may say "hey, it is just like Easter island, except their monuments are dedicated to the God of Tech".
"It is the first time since 1972 that humans have travelled outside of the Earth's orbit." But they're not tho (Earth's gravitational dominance extends 4x the distance to the moon)
> It is the first time since 1972 that humans have travelled outside of the Earth's orbit.
They mean outside of low Earth orbit (which basically means further away than the ISS). The phrasing is not ideal.
> Earth's gravitational dominance extends 4x the distance to the moon
"Earth's gravitational dominance" is not a single thing; it depends on what kind of "dominance" you're talking about.
For example, even though the Moon is usually described as being in orbit about the Earth, its orbit is always concave towards the Sun. In other words, its net gravitational acceleration is always towards the Sun--even when the Earth is on the other side of it from the Sun. So by this criterion it's not in orbit about the Earth, it's in orbit about the Sun, doing a complicated do-si-do with the Earth, also in orbit about the Sun.
I'm not sure what definition of "dominance" you're using that extends the Earth's "dominance" to 4 times the distance of the Moon.
This video explains what you’re talking about re the moons orbit always curving toward the sun, and also mentions Earths gravitational dominance.
It’s about the suns gravitational pull on the moon dominating over the Earths gravitational pull on the moon, but that due to the centrifugal force (there isn’t one, so conservation of angular momentum) the Earth's gravitational pull dominates.
https://youtu.be/KBcxuM-qXec
The statement I made about acceleration due to gravity was with reference to an inertial frame centered on the Sun, in which there is no centrifugal force. The video you reference takes that viewpoint during its first part.
The claim about centrifugal force refers to the Hill sphere, which is a different notion of "gravitational dominance". The basic idea behind that is that, while the Sun's force on the Moon is greater than the Earth's, it varies in space, in the region where the Earth and Moon are orbiting, much less than the Earth's does. So we can "subtract out" the Sun's gravitational force, so to speak, since we can approximate it as constant in the region we're interested in.
The video, however, bungles this somewhat, because its claim about "centrifugal force" is made in a frame which is centered on the Sun--but rotating at the same rate the Earth revolves around the Sun. But nobody actually uses such a frame! Doing that would be silly. The natural frame for us on Earth to use if we "subtract out" the Sun's gravitational force to analyze the Earth-Moon motion is a frame centered on the Earth.
In this frame, we can say that the Moon orbits the Earth, not because there is some "centrifugal force" canceling out the Sun's force, but because we've subtracted out the Sun's force by centering our frame on the Earth. Or, to put it another way, we're treating the whole Earth-Moon system as freely falling in the Sun's gravitational field, and as long as the Sun's field is, to a good enough approximation, constant in the region we're interested in, we can simply ignore the Sun's gravitational force. (This viewpoint is much more natural in General Relativity, where "gravity" is not a force at all to begin with.) Such a frame is called an "Earth-Centered Inertial" frame, and it's the frame that's being used, for example, to manage the Artemis II spaceflight.
Sounds like you might have explained it better than the video.
Technically correct, the best kind of correct. After all, the moon is in Earth's orbit.
One would hope they’re still in Earth’s orbit - if they’ve achieved escape velocity they’re not coming back.
So if we’re being technical I think they did achieve escape velocity? But the moon’s gravity and some timed burns will slingshot them back.
But one could imagine, as a failsafe, arranging things so that Integrity was in fact still in orbit around the Earth, as a sort of "backup" in the event that they somehow missed the moon's slingshot effect.
Theyre travelling to a region of space where the moons gravity is more important than the earths though. I think that counts
It really just is a blue marble floating in nothingness.
How are people still flat-earthers after stuff like this
Because without the network effect of adequate education, scientific understanding doesn't scale.
What does scale, unfortunately, is arrant nonsense.
I'm pretty sure people claim to be flat-earthers as a lark.
I know some MAGAs. I promise you they believe it 100%. They often talk of ice walls and one asked me if the Artemis mission would "break through the firmament"?
There is a huge side of TikTok and Reels that most of us here would never find on our feeds which is dedicated to insane conspiracy theories and constitutes a large amount of the media that MAGAs etc consume.
If you think MAGA followers believe in flat-earth, you've deluded yourself badly.
They aren't, what you see is a combination of trolls and propagandists; very few real human beings actually believe in such things.
You can't claim to have superior knowledge if you admit you're wrong.
Maybe I'm just a dumb optimist, but I've always assumed that the flat earthers started out as an enteraining debate club intentionally trying to prove something impossible just for the challenge, which got overtaken by a tiny number of vocal idiots. I have heard they largely have moved on to Qanon, which tracks.
The initial modern flat earth movement was absolutely trolling, no doubt about it. But as the myth grew, enough grifters and actual idiots glomed onto the idea that it became what it originally mocked. Poe's law and all that.
Similar to the "I fell in love with an AI!" folks, it's largely undercover salesmen hawking their goods to the gullible.
...sounds like the No-Kings people
If I have to choose between the people protesting authoritarianism and those embracing it, I’ll take the former.
Yeah, certainly not the kings cult.
This photo could be easily faked. I don't believe the Earth is flat, but I also don't think everybody on the planet should be 100% on one side of a discussion. Even if flat-earthers are kinda dumb, I think it's worse to force everyone into intellectual submission just because you're "right".
Even if clearly one side is correct without any doubt whatsoever, beyond any question? Such as 2+2=4 -- we should accept a situation where some people insist this is not true? It seems irrational.
>I think it's worse to force everyone into intellectual submission just because you're "right".
I think it's worse to consider the acceptance of reality as being "forced into intellectual submission" and to use scare quotes around "right."
There are discussions that everyone on the planet should be 100% on one side of and this is one of them. It is literally just wasting everyone's time to entertain the premise that opinions to the contrary hold any value.
Why is spectacular in quotations? I keep seeing this in headlines, is it because they're quoting a single word?
It’s a BBC journalistic standards thing; the BBC doesn’t want to express an opinion about the image, they are relaying that as a quote from someone about the image. The word “spectacular” is attributed to NASA in the article.
Yes
It's lazy "editorializing"
Quite the opposite.
Comparing the final two images of taken of earth in 1972 and 2026 respectively; does the 2026 (left) image look murkier and less crisp to anyone else?
Surely our camera gear is exponentially better now? Is the reason for the new image being ‘murkier’ due to light, pollution or something else?
> Surely our camera gear is exponentially better now
They are better, but not exponentially. You can't beat physics, film cameras can still compete in terms of dynamic range and resolution, the optical elements haven't changed that much. The 1972 photo was taken on medium format film, which is twice the size of the sensor area in the modern one, which means more photons and less noise. The recent image was take at a really high ISO, which adds to the noisiness.
1972 -> taken during daytime 2026 -> taken during nightime
Very cool. Along the same lines the EPIC::DSCOVR mission has been taking photos of the earth since, I believe, around 2015.

What is that bright star like object on the bottom right? Is it Venus? I’m guessing it’s Venus because it’s much brighter than a star would be.
NASA confirmed it is Venus, yeah.
This picture wasn't taken from far away, but I thought about that quote from Carl Sagan -
Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.

A new hello.jpg?
Why is the old image so much more blue? Did pollution increase cause this change in color over time?
One was taken during daylight on film, which needs to be processed and scanned, the other one was taken at high ISO during night time on a digital camera.
So much interpretation is done on colour on each step of the way that it's not surprising the colours are looking different.
If you're confused what you're looking at, turn it upside down.
From the article:
> The Earth appears upside down
Which I find to be a rather interesting take.
West Africa & Gibraltar strait
The comparison pictures look like there is more dust in the air today. They don't explain this effect, so I assume it is related to time of day the photo was taken, or camera settings, not actual dust accumulation compared to 1972. However, the direct comparison gives the impression they want people to interpret like the air is getting dirtier?

How come the pictures have such bad quality ? Is it a bandwidth issue ? Or there are really constraints that are not so obvious ?
Because fundamentally it is a large object illuminated by sunlight.
No, it's BBC's compression of that image.
Look at the original: https://www.nasa.gov/image-detail/fd02_for-pao/
It's grainy, but the detail is terrific.
No GPS coordinates in the EXIF data. Would've been funny.
@dang, mods: maybe this should be the post's link. The image quality is much higher.
It's the night-side Earth, taken at a high ISO value to keep shutter speed fast to prevent blur.
Ok thank you, makes more sense, I thought it was the day-side
Yes, I was also confused when I first saw it – how could the aurora be visible?! The bright sliver of atmosphere in the lower right is, of course, backlit by the sun which is itself eclipsed by Earth. It's the near-full moon that provides most of the illumination here. Besides both auroral rings you can also see airglow, city lights, and lightning flashes, it's a marvellous photo.
But why not film everything like skydivers do in 8K 120fps from every angle and live stream it? After all, it is 2026...and near-Earth missions like the Moon can now support hundreds of Mbps (even approaching Gbps with laser communication). In the age of live streaming, wasn't this taken into account? All we got is a choppy 480p video feed, if that.
wait why is it round?
The shot is from directly above the disc and the great turtle is hidden beneath it.
It's not really round, it's just a lens aberration.
To paraphrase Carl Sagan: insignificant plant in an insignificant galaxy and there’s a good chance we’ll annihilate ourselves.
Why didn't NASA or the news agencies rotate the image so North is up? and slightly to the right. That would make Africa instantly recognizable as that's how maps are imprinted in our brains.
There is no "up" in space, so that wouldn't be editing the image I feel. The camera just happened to be oriented "upside down".
I was thinking the same thing, but then I decided to embrace the frustration of the image. It's reminding us that the pictures we have in our heads are kind of fragile. They don't prepare us for a live encounter with Earth from some random angle in space.
This is kind of profound.
I personally prefer to view it in the same orientation the photographer saw it in their viewfinder. Makes me feel more like I’m inside the vessle looking at the planet.
If you live in the southern hemisphere most pictures of the Moon that you see online look upside down compared to ones that you take yourself.
I asked a different question in my mind, who says it "appears to us as upside down"? I would think if you lived in Patagonia, the south pole is "up".
What a gorgeous sight to behold!

whats different between this and all the other pics of earth from various space devices
I saw someone point out on reddit that this probably the first digital picture of the whole earth (well, 1 side of it) taken by a person
Apollo used film and it's been a long time since anyone has gone past LEO
Haven't any of the space probes taken such pictures as they left to wander through the solar system?
There something amazing about that. Thanks for pointing it out!
It’s taken by a human on the way to the moon.
That's enough for me. There was also much hype about a new blue marble picture, but I'm ok with that.
This is the night side.
Taken by a different camera, from a different location, at a different time.
Very cool
WOW!!!!
Where's Antarctica?
Just behind the horizon somewhere on the top right, or maybe some of those clouds are already it.
You can see for yourself in Google Maps if you enable the globe view, unfortunately it seems I can't share a direct link.
truly stunning picture
Can I see the thin band of atmosphere?
Yeah I'm pretty sure that's atmosphere since it does scatter light slightly
this ought to put flat-earthers completely down. :)
I often think about what an amazing time it is to be alive and how amazing all the tech we have at our fingertips is. But I am also incredibly saddened by the fact that I was probably born just shy of routine space travel. I can not even imagine how amazing it would be to look down on earth and see it in its entirety. Hopefully my kids or my grandkids will be able to achieve my dream and do exactly that.
If you had routine space travel, you would be upset that you can't time travel.
Hello again dot.

A beautiful reminder of what's possible with photography when you're using more than a comparatively crappy iPhone Pro Max camera. (Oh and taking the shot from Outer Space.)
That picture of the "dark" Earth is most fascinating because everyone has seen a million images of Earth before, but how many have seen it in this view. The image by itself says a little about the Earths place in the planetary system.
Can't decide if this is "MOEAGARE ARUCHIMISU" moment or a "Transcending Time" moment.
Does there exist a camera that can zoom into a single person from this distance?
Nope, not today that can be easily brought in space. Plus the atmosphere interfering.

No it didn't. That would be catastrophic and likely fatal. They are going to the Moon, which is also in Earth orbit.

Come on flat-earthers. I know you are out there. Lets hear your crazy rant about how this is a fisheye lens on a weather balloon or a webcam atop the eiffel tower. Why can't we see the poles? And is that an ice wall on poking up in the lower-right quadrant of the disk?

There is no point engaging in any way with people who believe in such "theories". They are like trolls, the only way to deal with them is not at all. Don't engage, don't disagree, just nothing, total silence. One can choose to be a wilful edit and waste your life and time on complete bullshit, but the rest of us should just ignore those people completely.
Ya, but eventually they all wind up wearing furs and carrying spears as they storm the gates of some government building. Its all good fun until people start to die. We laugh as soveriegn citizens are yanked from thier cars. Harder to watch are the vids of them pulling guns on police.
Conspiracy theorists need to be kept in check. Disengagment is easy but it doesnt help.
This was a fantastic YouTube video on flat earther beliefs from a few years ago: https://www.youtube.com/watch?v=JTfhYyTuT44
Spoiler - they mostly switched to QAnon instead.
Oh, wait, in addition to their usual conspiracy theories, now they can also claim that this is AI-generated!
Flat Earth is a distraction or a way to ridicule any counter-narrative to anything scientific.
When a cosmologist says that a planet nobody can see exists and is made of x% helium and is y light years away etc etc with absolute certainty despite nobody being able to go there and witness any of it (look how wrong they were about Pluto’s appearance), then you can always just say “what are you a Flat Earther” and easily discredit any doubt I have in these extraordinary claims with underwhelming evidence.
Any idea you want the public to oppose, you can create and market an adjacent thing, like Trump. You can throw all the ideas you want to oppose in the Trump bucket and if anyone supports it it’s probably because they’re a Trump supporter right?
See you’re very very easily programmed, like clockwork.
> a planet nobody can see exists and is made of x% helium and is y light years away etc etc
Yeah, because this is high-school curriculum.
https://www.jpl.nasa.gov/edu/resources/lesson-plan/using-lig...
> with absolute certainty
It is taught that the scientific method provides evidence, not certainty, in middle school science curriculum.
> It is taught that the scientific method provides evidence, not certainty, in middle school science curriculum.
FWIW, this fact isn't taught properly or normies are somehow unable to process it.
There's this popular dismissal of tech people, saying that "they think in 0s and 1s, but world is shades of gray", but in reality, it's almost everyone else that thinks in 0s and 1s - STEM people and people in/into similar fields (like medicine) are usually forced to understand nuance due to nature of their interests/occupation, but everyone else seems to operate in purely binary mode, and what's worse, whether something is true and false isn't even correlated much with objective reality, and mostly with one's personal feelings about how things should be.
(Now, to be an equal opportunity cynic, in my experience, the concept of categories and taxonomies being arbitrary - invented and assigned by people, and judged by their usefulness, as opposed to being inherent facts of nature that are discovered - seems to be hard for even STEM people to process, for some reason, at least based on my observations and the number of conversations I had about this with all kinds of people.)
I do not know what you mean about "how wrong they were about Pluto’s appearance".
Since when I was very young and until now the amount of information about Pluto has continuously increased, so now we know much more about it.
For example now we know that Pluto is practically a double planet, having a relatively very large satellite. This was not known when I was a child, e.g. at the time of the first NASA Moon missions.
However, I do not remember anything wrong. Many things that have been learned recently were previously unknown, not wrong.
If you refer to the fact that Pluto was reclassified as a dwarf planet, that is also a case of information previously unknown, not wrong.
This planetary reclassification was not the first.
When Ceres was discovered in 1801, it was considered the 7th planet, after the 5 planets known in antiquity and Uranus that was discovered a few years earlier. (The chemical elements uranium and cerium, which were discovered soon after the planets, were named so after the new planets, as their discovery impressed a lot the people of those times.)
However, soon after Ceres a great number of other bodies were discovered in the same region and it was understood that Ceres is not a single planet, but a member of the asteroid belt.
Exactly the same thing happened with Pluto, but because of its distance, more years have passed until a great number of bodies have been discovered beyond Neptune and it became understood that Pluto is just one of them, i.e. a member of the Kuiper belt, so it was reclassified, exactly like Ceres.
> ...discredit any doubt I have in these extraordinary claims with underwhelming evidence.
Something unfortunate about our media environment is that science news is a dumbed down summary of a dumbed down summary of a dumbed down summary. These issues you're flagging, a lack of evidence and overstated certainty - they're an artifact of the reporting process. If you work your way back to the original sources, there will be a heck of a lot of evidence and it will carry error bars (so the certainty is precisely & appropriately stated). There's bad or even fraudulent papers out there but there's a huge amount of good science being done by honest researchers who are just as concerned as you are about the quality of the evidence and the degree of certainty.
Eg, there really is a compelling explanation of how we can know the composition of a gas giant light-years away, and it isn't invented out of thin air, it's been 100+ year process of understanding spectroscopy and cosmology, building better telescopes, etc. It's the culmination of generations of scientists pushing the field forward millimeter by millimeter.
Your argument is against large generalizations and straw man arguments, and to prove it, you.. use a generalization and straw man argument?

The only real difference between the "spaceflight" in the 1960's and today is that these pictures don't need to be hand painted - you can render them in Blender in a single day.
But yeah, sure. With the amount of fake stuff on the internet including AI image generation, we're expected to believe that the US government dumped billions of dollars into going to space when they could give the appearance of doing so for a few bucks in nano banana credits? Hah.
Im curious, so the rocket definitely took off, where did it go?
They couldn't do that for "a few bucks of nano banana credits" though. You could generate the imagery but that's only one line of evidence. A launch is easily detectable through multiple signals.
Why would Russia and China and any other country with any degree of astronomic capability that the US has an adversarial relationship with just let them get away with lying to the world? Why wouldn't they take the opportunity to humiliate the US by revealing that no launch happened and that they cannot detect the spacecraft?
How would they prove that no launch happened? There isn't conclusive evidence of an absence of launch, and if there were it would be accused as being fake and a ploy from American enemies to discredit them.
> and if there were it would be accused as being fake and a ploy from American enemies to discredit them.
Yeah so, the soviets were pretty good at dodging things like that:
https://en.wikipedia.org/wiki/1960_U-2_incident
> There isn't conclusive evidence of an absence of launch, ...
A launch is detectable seismically, visually, on radar, etc. There's a lot of investment in being able to detect launches (to detect the launch of nuclear weapons). It would be screamingly obvious if the launch was fake. It would absolutely be conclusive if there were no seismic activity, no radar return, they couldn't detect the spacecraft presently, etc. At least for a definition of "conclusive" that can be operationalized - conclusiveness is a judgement call about when evidence is sufficient and not reaching some theoretical 100% certainty. Which can't possibly be reached for any claim for the reason you outlined; you can always invent some negative counterclaim that can't be entirely dismissed, even for claims like "the sky is blue".
It's also pretty easy to find people who were physically there to witness the launch. This wasn't a secret bunker or a barge in the middle of the ocean. It was in Florida in the late afternoon.
> ...it would be accused as being fake and a ploy from American enemies to discredit them.
Hundreds of thousands of people around the world have access to this data. Astronomers, geologists, petroleum engineers, backyard amateurs. The conspirators could muddy the waters but they couldn't ultimately prevail. It is many orders of magnitude easier to go to the moon than to convincingly fake it.
I object to being included in this image without a model release and demand that pixel be removed.
Your comment history suggests you're in the US, so you should be pleased to learn that you weren't included. The visible landmass is northern Africa, with a smidge of the Iberian Peninsula visible.
South America is visible on the right, and it looks to me like part of North America might also be pictured close to the horizon.
Higher-resolution image: https://www.nasa.gov/wp-content/uploads/2026/04/art002e00019...
Oh, good point. I missed South America under the cloud cover. I guess the Eastern edge of the US would indeed be visible as a highly distorted smudge on the edge of the visible surface.
For a view of roughly the same half of Earth, but with less clouds, if you rotate the image clockwise by 150 degrees you get roughly this viewpoint of the earth: https://earth.google.com/web/@3.63731074,-23.1618975,-2690.7...

Thank you. I have having trouble making sense of the orientation. My first thought was misshapen Australia, but where Spain nears Africa is much different than Australia and Tasmania. Also, they forgot New Zealand... while common for maps, I would expect it to show up in a photo.
If they somehow manage to get another photo which features Australia without New Zealand that would be the best Apr 1st joke I've ever seen
Thanks I was looking for an orientation comment.

I don't understand why media, such as BBC, keep uploading heavily compressed versions of photos that could be beautiful. The original has grain, sure but that's not a problem. The BBC version is horrific. Are they trying to save on bandwidth in 2026?
It's highly reasonable for them to limit image size/quality to whatever looks fine to 98% of their readers. They store and serve an absolute ton of ever-changing content to browsers/apps; The very small (and likely revenue-negative) contingent of highly motivated people can find the originals if the images are especially noteworthy like these.
If the content loads fast, more views are given and more data is collected.
