The making money bit is a long way off, but in theory the moon would be a staging post for exploration and exploitation of Mars and the Asteroid belt.
If you can sort the engineering side of mining asteroids the quantity of materials available are believed to be mind bogglingly huge.
The spin off benefits of such a project are similarly huge, but difficult to quantify.
I’m just hoping that the U.K. will have some involvement, just like last time.
