To test the technology to sustain a long term mission. We need to develop new processes to find resources in a inhospitbale world where hydrogen and oxygen arent readily available. It is also easier to leave moon orbit than earth orbit, so it has been discussed as using the moon as a jumping off point for the longer range missions like mars because you would need less propellant. Either way, it is all about testing technology.
Fun fact, a moon habitat would be great for those with mobility issues, and if you had a big enough open space, you could wear a wingsuit and flap your arms like a bird to fly. Sign me up either way, and im going to finally get that full auto laser blaster ive had my eyes on...
I appreciate that perspective, thanks!
Another serious question: Why do we need a sustained mission? I’m having a difficult time embracing the ROI of such things
