    Are full size/larger images available somewhere? 1920x1280px seems low.

    Edit: Found 'em: https://images.nasa.gov/search?page=1&media=image&yearStart=...

      To be fair they "only" have a 20 Mbps laser uplink from the capsule to Earth, and that's shared between all the systems and uploading images/video.

      The external shots seem to just be from the GoPro strapped to a solar panel. Didn't seen anything that looked like the shots from the Nikons onboard. Was hoping for a couple, but I know I'm just being greedy wanting all the pics

      edit: exif data shows some are from a Nikon. I just want to see them all!!! My greedy line still plays

    • aanet 1 hour ago
      I was hoping that they used a medium format camera like Hasselblad or something for the larger pics... but no such luck. I guess weight might have been one factor.

      Still, the pics are mind blowing. Out of this world, tbh

      • dylan604 1 hour ago
        A 20.8 megapixel 5568 x 3712 pixels is not a shitty image. When we get to see those images, they will be much better than the GoPro images we're seeing

    There is something uncanny about the bandwidth and quality of all the artifacts coming from this mission.

    I've subsisted on photos from the Apollo missions and artistic renditions for so long that seeing the modern, high resolution real thing to be quite stirring in a way I didn't expect. It actually does make me believe that the future could be quite cool.

      I cannot wait until we get 4k video of people walking on the surface, kicking up dust.
    • dylan604 1 hour ago
      We haven't even seen the full quality images yet. They've commented that the live feed from the GoPro is a limited bandwidth because they have to share the bandwidth with running the capsule. The images from the Nikons onboard are just scaled down. My initial guess was from an export specifically to get an early dump to get everyone on the ground chomping at the bit something to see. They'll get the full images when the SD cards splash down. When those are released, I'm expecting quite a few OMG images

      Yeah, I think we got so accustomed to that analog look that seeing them like this feels almost like viewing a World War I photo in full color and 4K.

    I have to admit, I've been an Artemis hater ($4 billion per launch lol) but the experience of watching people go back around the Moon has been incredibly inspiring, and it proves to me that maybe we can still do hard things

      > $4 billion per launch lol

      The US spends almost that much on net debt interest each day (~$3 billion/day[0]). Not that adding to the debt helps at all, but the old proverb about being penny wise and pound foolish seems relevant

        The absolute cost isn't the problem, it's the value that we're getting from it. SLS and Artemis are both incredibly expensive and ramshackle programs, and regardless of how bad the rest of the USG might be in terms of their cost, or value, if you are a true space fan and a true American space fan, you should want this little corner of humanity to hold itself to a higher standard.

        Acceptance of over costing and under delivering is exactly why the US is stuck with SpaceX as its prime space launch provider. It's only through the miracle of the vanity of billionaires that there's even a realistic second choice (Blue Origin) that might develop.

        It's also this type of attitude that let's us be in a situation where we honestly don't know how well the heat shield will work on reentry (SLS launches are so expensive, and so slow to build and prep to launch, that we cannot fit in a uncrewed mission between 1 and 2 to test or validate fixes or models).

        If Artemis as a program succeeds, it will be despite the incredible graft, pork, and ass covering, not because of it. I want Artemis to succeed because the achievement will be beautiful and amazing, and I want everyone to be safe and sound. I want Artemis to fail, to force a reckoning. I still believe that America has great things to offer to the world, but it's not going to be able to do that by muddling it's way through and cobbling together random pork filled programs into a vaguely inspiring shape.

          This is about to change.

          New NASA administrator Isaacman has redone the Artemis program. The changes were announced at the Ignition event a few weeks ago:

          https://www.nasa.gov/ignition/

          If you read one thing, read the sides on building the moon base:

          https://www.nasa.gov/wp-content/uploads/2026/03/2-building-t...

          The goals it to fly often - adding a SLS launch to 2027 and a second launch to 2028. This drops the cost-per-launch, which is mostly fixed. It redoes SLS to make it less expensive and more capable. It moves the lunar space station down to the surface of the moon.

          And it's budgeted at $10B/3 years, which fits into NASA's budget.

          Isaacman took the Artemis program and fixed it. The reckoning came, and it's looking good.

        Spends, or accrues?

        • bruckie 7 minutes ago
          Same thing (for now, at least). The U.S. has only defaulted a handful of times, none that I'm aware of since 1971.
      • ToucanLoucan 2 hours ago
        Also we spend that much every 4 days we're in Iran, and that's only ONE of our neo-colonialist irons in the fire, as it were.

        If you want to make the US financially solvent, cut defense. Defense LAPS every other budget category. Whether you want to take the conservative position on why that is (our allies freeload on our defense spending) or the Progressive one (the U.S. is an empire in decline and every major empire through history has spent vast sums to maintain itself why would the U.S. be different) doesn't change the fact that our military budgets exceed over a dozen other nations' combined, the vast majority of whom are allies.

          I suppose it matters how you lump things, but for federal spending:

            - $678 B, Social Security
            - $478 B, Medicare
            - $425 B, Net Interest
            - $419 B, Health
            - $412 B, National Defense
            - $320 B, Income Security
            - $184 B, Veterans Benefits and Services
            - $75 B, Education, Training, Employment, and Social Services
            - $53 B, Transportation
            - $43 B, Administration of Justice

            Not all of those are discretionary spending? Maybe not equivalent to include, for example, Social Security.
          • fwip 1 hour ago
            I think the common miscommunication here is that defense is the largest part of the US discretionary budget (about half overall), but that doesn't include those non-negotiable things like Social Security, Medicare, etc .
            • actionfromafar 24 minutes ago

            "Please note: Values displayed are outlays, which is money that is actually paid out by the government. Other sources, such as USAspending, may display spending as obligations, which is money that is promised to be paid, but may not yet be delivered."

            The Biden administration's FY2025 defense budget request was $850 billion for the DoD, with the total national security budget reaching over $895 billion. The FY2026 proposal submitted by the Trump admin is 1.5 trillion for DoD.

      This is not a lot of money on a nation-state scale. It's equal to giving every person in the US about US$12.

    • chrismcb 2 hours ago
      Ignoring the fact that we aren't using money for rocket fuel (that is people are benefitting from us spending that money) the potential upside is immense. There are a time of resources available in the asteroids and a moon base makes mining those resources easier and cheaper.
    • sublinear 2 hours ago
      The longer term value of having moon outposts for observation, mining, etc. will pay off massively.

      This is way bigger than just putting people on the moon or hubris. It's the prerequisite for everything we've also said about Mars. Elon just muddied the waters so much that people are so negative about anything else.

      $4B is chump change for the U.S.

      Gavin Newsom alone wasted (laundered?) billions of dollars in California. The United States can send 10 rockets per day and wouldn't even feel the financial impacts of it. The states individually waste millions per day.

      • Fourier864 51 minutes ago
        Ok I realize you're making a point, but 10 launches a day comes out to about $15 trillion a year, that's like half of the US GDP

    I wish they would’ve flown by and taken a picture of the Apollo 11 lunar landing site.

    I think it would’ve been a super cool throwback to the history of lunar exploration; maybe it’s just me but I think it would’ve been really exciting. It would basically be the like visiting a UNESCO (moon?) heritage site.

    • rootusrootus 5 minutes ago
      They would have needed a hell of a lot more camera for that, right? Even the best DSLR with the best lens is going to have a lot of trouble resolving something that small at over 4000 miles.
    • CookieTonsure 13 minutes ago
      The main point of the voyage was to see the far side, and also to report on previously-unseen portions of the Moon that hadn't really had human coverage in the past.

      Since all the Apollo landings were on the near-side of the Moon, they were in fact less accessible to this crew.

      My disappointment lay chiefly in their L.O.S. periods, because in 2026 why does Earth lack operational satellites that could relay comms from the other side? Or a space optical/radio telescope that would benefit massively from the darkness and shielding of a Moon-sized body? No humans necessary for that. Of course, you couldn't power such a craft with solar power...

  • dylan604 1 hour ago
    I listened to pretty much the entire fly by yesterday, and I was imagining how I would have spent my time at the windows with a camera. Listening to the comms made me think of that episode from From The Earth to the Moon where they take the astronauts out and give them geology lessons so they could be more productive with their descriptions.

    I was also very curious of their descriptions during the eclipse where the Earth shine was lighting up the dark side of the moon to such a surreal look they couldn't really describe it. They were even commenting that they didn't feel the photos being taken were doing it justice either.

    I also was wondering if they will make any modifications to the capsule since covering a window to block the Earth shine caused concern on the ground from some of the readings they were getting. Assuming it was overheating as they redirected air flow to the window. Then again, the following missions won't be so concerned with a single fly by so probably not something they'll address.

    I think my favorite of all these images is https://www.nasa.gov/image-detail/amf-art002e009287/. The sheer size difference, while simply a trick of perspective, makes Earth feel tiny and insignificant.
  • SegfaultSeagull 59 minutes ago
    Can someone ELI5 how it is one side of the moon is never seen on Earth? The moon orbits and also rotates, does it not?
    • willis936 55 minutes ago
      The gravitational pull of the moon lifts up the ocean to cause tides. Well the Earth's gravitational pull is so strong on the moon that the heavier side of the moon always faces the Earth. This is called tidal locking. So the only way to ever see the far side of the moon is to go there. Humans have gone there before, but almost always during an Earth "full moon", which means the far side is unlit. We do have full images of the far side of the moon from remote probes, but the 21% of the far side that was lit had human eyes on it for the first time ever.
    • written-beyond 57 minutes ago
      The moon is tidally locked to earth, we only ever see one side.
      • Georgelemental 54 minutes ago
        To add: this happens because the parts of the Moon that are closer to the Earth are pulled in more by Earth's gravity, compared to the ones further away.
      • kshacker 54 minutes ago
        Is it 2-way? I guess moon see all around earth, or no?
        • eterm 42 minutes ago
          Consider what it'd mean if there were parts of the Earth that could not be seen from the moon, it would also mean those locations could never themselves see the moon.

          Ignoring the orbital period implications, I think it'd be bigger news if either US or Europe, or Asia couldn't ever actually see the moon.

        • johnwalkr 43 minutes ago
          If you are on the near side of the moon[1], you will always see Earth see around Earth as it rotates and as the moon orbits it. You will also see it in different phases, like how we see lunar phases from Earth. If you are on the far side of the moon, you will not see Earth at all as you will always be facing away from it.

          [1] The Earth does move in the moon's sky a bit. If you are on the near side but getting close to the far side, the Earth will be below the horizon sometimes.

    • ijidak 54 minutes ago
      I believe it's caused by even the slightest imbalance in mass. Because the moon is so close to Earth, the imbalance causes gravity to be slightly stronger on one side than the other side. Eventually, that leads to no rotation at all.

      I imagine most bodies rotating around a second object will eventually lose their angular velocity.

    • SilverElfin 55 minutes ago
      Yes and its rotation is synchronized to earth. See the animation at https://en.wikipedia.org/wiki/Tidal_locking

    • dylan604 21 minutes ago
      They said they were able to see a few planets during the eclipse. I know they definitely saw Mars as they were discussing the red color. They saw Venus which was visible in the live feed from the GoPro on the solar panel. IIRC, they were thinking Saturn would have been visible. My guess is the really bright dots are planets. It looks like some horrendous compression artifacts along with some possible lens distortion. My exif app says no exif data in the jpg you linked. Did you come to that image from their website that provides the EXIF to see what lens it was? Nothing looks like a galaxy in the image to me.

      Edit: After further looking and some zooming into it, I'd say the bright dot closest to the moon is Venus, the next one has a red tint making it Mars, and then the last one would be Saturn with the rings. There might be a couple of galaxies in the upper left corner. I was quick to dismiss and blame on compression. The benefits of not having to shoot through atmosphere. I wouldn't have expected that detail in what I'm assuming to be a fairly fast exposure

    • sho_hn 2 hours ago
      Maybe I'm an eternal optimist, but sounds to me like they actually tried to put themselves into space, made the assumption that anything visible past the moon must be further out and were left with "wait, I thought it was supposed to be red?"

      Uninformed, but not ignorant and perhaps even interested. I hope your response started with "No, actually, even cooler: ..." and you made a space fan that day.

    • dboreham 1 hour ago
      I'd be genuinely curious to see a list of the things they had heard of, since Artemis has been in the news constantly for a month. E.g. have they just not heard of anything (consume no news), or are they in some news silo that excludes rockets, and if so what other things does it include? We may be missing something important that we've never heard of!

    I started rewatching For All Mankind a week or so before the Artemis II launch, so it's been pretty wild to watch an alt-history about people going to and settling on the Moon and Mars, and then to see real life people just starting to return to the Moon at the same time.
  • wishfish 1 hour ago
    Zoomed into several of the lunar surface photos and noticed some of the very small impact craters are in a regularly spaced straight line.

    Looks to me as if a meteorite came in at a shallow angle and basically skipped across the surface. Leaving dimpled craters as it bounced. Looks very similar to rocks skipping on a pond. Am I correct or is there another explanation for these?

    • xnx 1 hour ago
      A chain of meteors would strike the surface in a line as the moon moves
      • ninkendo 59 minutes ago
        A single “rubble pile” asteroid will easily break apart when nearing a celestial body, once it crosses the Roche limit. It will break apart into a perfectly straight line too (at least the impact craters will.) I would guess most of the straight-line series of craters are all caused by something like this.

      Why is normal in quotes? Do you mean visible light vs filtered monochrome with false-color outputs or infrared/radio/x-ray like some other telescopes use? Would that be the abnormal you are referring? The Apollo images were taken with Hasselblad film cameras that were "normal" cameras[0].
