there can only be one thing they intend to do now, investigate the water situation. But it seems a bit strange that they've only just discovered this now. Hard to believe almost.
Not quite. The presence of water has been known for a while, they just didn't expect that it was that prevalent. It's one thing to go to the little pockets on the dark side, quite another to be able to select a site to explore where other resources are abundant. This discovery opened up the playing field.
What steps need to be done to get someone there again? What are they planning to do once they get there?
Resource utilization is the big drive. It will start small with producing water, oxygen, fuel, using 3D-printing techniques to create structures, etc.
Those would be the main goals and, of course, the first woman on the moon.
