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.

Some of my favs:

1. The moon eclipsed, with the Orion capsule (outside POV, from GoPro) - https://images-assets.nasa.gov/image/art002e009567/art002e00...

2. The moon eclipsed, with the Orion capsule, and Earth crescent (outside POV, from GoPro) - https://images-assets.nasa.gov/image/art002e009567/art002e00...

3. Crescent Moon, Crescent Earth (my fav!!) "A New View of the Moon" - https://images-assets.nasa.gov/image/art002e009287/art002e00...

4. Artemis II in Eclipse (new fav!) - https://images-assets.nasa.gov/image/art002e009301/art002e00...

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.

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

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.

Very cool pictures, especially those ones backlit by the Sun are something new. ie real photos that we usually only see in sci-fi games or movies.

But the real question is: Who of those 4 clogged up the toilet? That's what the public demands to know.

I cannot fathom what it must be like to witness this in-person. The pictures are spectacular but to spend time experiencing it outside the window in your proximity must be overwhelming in the most incredible way.

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?

A chain of meteors would strike the surface in a line as the moon moves

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.

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?

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.
