缺乏实际的月球返回能力和对月球环境的安全担忧

It's hard not to see this as a consolation prize. In 1969, we went to the moon. In 2026, with all the benefits of a tech industry that has become ever more powerful, with endless money poured into innovation, our 'rough guide back to the moon' is an AI model that maps it. It's powerful and impressive, of course, and doubtless very useful to researchers, and space exploration is not a priority--all of that is true, sure. But to have the fruits of 50+ years of technological progress result not in going back to the moon, or onto other challenges, but just a refinement in looking at the moon. Is this the best giant leap we can muster now? So much innovation and yet we lack a capability we used to have. I know there are all sorts of ways to explain this away, but it still makes me sad.

did not know we have -246°c to play with, which means the potential for the whole set of useful volatiles is there, not just water/O2/H2, and given that there is also the potential for +121°C very close to cold deposits, gives most of the basics for refining a whole host of molecules and compounds. Non of that changing the fact that being on the moon for any extended time is going to SUCK, the dust is horrible in every possible way, low gravity will weaken , radiation is heavy, and all of the many other risks will add up to a poor career choice, so the compensation will have to be 1 tour, and retire in guaranteed style. Basically flying a great big ass laser in a lunar polar orbit and zapping the shaded dark sections of craters while some other satellites watch the resulting gas

I'm not gonna lie, I'm closer to a conspiracy theorist and non-believer than I am to trust history on the moon landing stuff. Doesn't help that I wasn't alive when it happened, and that we haven't since gone again. It feels so nonsensical to me, I would love for someone to help me educate myself on it from a more grounded point of view that can satisfy my paranoia. Did we really go there? How come we (as in humanity, any other nation whatsoever) haven't gone again since?
