Thanks, that makes a lot of sense. For Mars I agree it’s not possible with the insane delay, unless AI will be able to automonously repair, something which might be possible in the future. But for the moon it would be much cheaper to remote control repairs. I’ve seen what surgeons can do with remote controlled machines for precision surgery. The delay still might be annoying but maybe that can improve by using laser instead of radio waves.
Cars are mostly, if not completely, built by precision robots. Why not have a precision robot replace and lubricate parts on the moon?
But first we need to find a way to mine on the moon in the first place. Regolith is extremity nasty stuff, nothing survives long with that tiny sharp dust. The people who went to the moon complained a lot about it. It gets everywhere, it sticks to every surface and shreds everything. There’s also the radiation, micro meteors and extreme temperature fluctuations.
