>>11381973Consider for a moment that the last time we went outside the kiddy pool that is Low Earth Orbit was in 1972, 58 years ago.
Consider for a moment that the only place we visited was the moon, for extremely short visits in glorified tin cans.
Consider for a moment that we have no experience in long term stays, which missions to Mars would have to be considering the fuel requirements to get there, the fuel requirements to get back as well as the long periods between good launch windows.
Now this is not to bring down the Apollo missions in any way, because they were amazing feats of engineering, but we've been doing nothing but sitting with our thumbs up our asses for two generations as far as interplanetary travel goes. As far as Artemis stands now, we might not even get a moon base, just a remake of the Apollo missions with a single manned orbit mission of Mars sometime mid 2030. "Soon" is a very relative term.
