NASA is reportedly mulling the construction of a floating Moon base that would serve as a launching site for manned missions to Mars and other destinations more distant than any humans have traveled to so far.
The Orlando Sentinel reported over the weekend that the proposed outpost, called a "gateway spacecraft," would support "a small astronaut crew and function as a staging area for future missions to the moon and Mars."
This is actually a good idea, using the Moon as a staging base for exploring the cosmos. Once we build manufacturing capability there, why not build spacecraft there? We can build bigger, more spacious craft so as to not lock up future astronauts in a closet for months or years at a time.
Numeric stability is probably not all that important when you're guessing.
