I agree with most of what has been said. But I think some people are missing the point that viable fussion strongly depends on Moon exploration. The Moon is the only plentiful source of H3 in our grasp. H3 is one of the most promising potential fuels for nuclear fussion. Strategically, going back to the Moon can possibly be explained by this. However, I honestly cant for the life of me understand the need for MANNED missions...? This seems absolutely wasteful!
