When I first heard about NASA's proposal for a crewed space station in lunar orbit I thought it was a dumb idea. If you're trying to go to the Moon why stop in the middle? It would cost extra fuel, and there's nothing there that you wouldn't have to bring yourself in the first place.
But I may change my mind. If NASA is actually planning a massive telerobotics operation on the ground, it's an excellent idea. You get real-time control over surface activities without all the expensive and dangerous landings and takeoffs. I don't know if that is what they are thinking though.
I'd like to see your opinions on the Gateway, be they pro or con. Any light on what NASA has in mind for this is especially welcome.
