Speaking of a moon Base, ESA has a plan establish one. They are planning to send two rovers that will be able to 3d print a base for humans. They are planning to send two rovers and an inflatable capsule. The inflatable capsule will work as a scaffolding for the rovers to print on. Two rovers will gather moon regolith around the inflated structure to create a protective shell, and their planned lunar base will be able to house 4 people. It's fascinating!
