Are the bright spots to the lower right in this photo galaxies or just camera artifacts[0]? Unreal photo either way. [0] https://images-assets.nasa.gov/image/art002e009301/art002e00...

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.…

Appreciate the detailed response. I think it would be a borderline miraculous photo if they are planets aligned in that way. Zooming they look more like artifacts or galaxies to me. I spend a good amount of time looking at planets from earth through binoculars and even with an atmosphere they resolve better than that.

Are full size/larger images available somewhere? 1920x1280px seems low. Edit: Found 'em: https://images.nasa.gov/search?page=1&media=image&yearStart=...

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

it was light gathering. the D5 they brought is a very old camera tech wise, but it was ideal for the low light photos of the eclipse. they also brought a Z9 for much higher resolution photos.

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?

If I am understanding correctly you are seeing https://en.wikipedia.org/wiki/Crater_chain which are craters caused by debris blasted out when another crater is formed.

Try this: https://www.flickr.com/photos/nasa2explore/

I don’t see TIFFs, so I assume the originals were JPEG.

We're so not accustomed to moon pictures taken with "normal" cameras. These almost look like 3D renders to me, it's incredible

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].

Earlier quoted context omitted.

> $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 0. https://www.cbo.gov/publication/61951

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…

>> is exactly why the US is stuck with SpaceX

For the last 20 years NASA has intentionally run their Commercial Crew Program, which has the stated goal of developing/fostering/funding the development of commercial providers for launch vehicles.

They, by plan they explicitly laid out and implemented, decided to rely on American commercial providers. And that's what they got. And in doing so, the program ended up producing the most prolific/successful launch vehicle in history.

>> It's only through the miracle of the vanity of billionaires that there's even a realistic second choice (Blue Origin) that might develop

Yes, this is another company which the NASA commercial program explicitly funded in order to get them to develop another launch vehicle.

I built a zoomable collection viewer for all NASA Artemis II + Apollo 8 gallery images at their full original resolutions—nearly 2 gigapixels across 104 images. Spanning 1968 Earthrise to 2026 Earthset:

Try different layouts with L (grid, masonry, spiral, etc.), filter by gallery or camera, WASD/Q/E/Tab to navigate.
