If it costs $10,000 a pound to get payloads to the Moon and it costs a billion $ to get 4 humans there or $250 million for each human, do they need to produce 100 lbs. of parts in 250 work days per year? 250*100*$10,000 = $250 million If they can’t do this much work why not just send up 100,000 lbs of parts?? I think that humans rather than parts will be able to do fine assembly tasks that teleoperated robots cannot. If they can fix a multimillion dollar robot that cost millions to get to the Moon when teleoperaters on the ground can’t get a robot to fix a robot they will be worth more than the mass of parts they produc
Given the 3 second delay for radio wave traveling between Earth and Moon, teleoperated robots will probably be good for slow and simple tasks. Humans on the Moon will be needed for complex tasks. And there will be plenty of complex tasks. As for me, i don’t even know how to make a hacksaw.
