Answers

Nasa has announced its plans to build a permanently occupied base on the moon by 2024. The lunar base is most likely to be built on the south pole of the moon. It will serve as a science outpost and the test bed for technologies needed for future travels to Mars.

The lunar base is envisioned to be built at one of the lunar poles, probably the south, to take advantage of the near constant sunlight for solar power generation. It would have an ‘open architecture’ design to which others could add the capabilities they want.
