Re: Without fusion power, why go back to the moon?
So far every thing we know about biology in different gravities is from studying things (1) in Earth Normal gravity or (2) in Ziggy. We have absolutely no idea how humans will react to prolonged Moon or Mars gravity. A lunar base, we can study people, rotate them home quickly if problems develop. Mars gravity can be better simulated on the Moon or apparently the ISS, which is where I would have studied it but I wasn't asked.
