We talk a lot about going to The Moon again, but what about very high Earth orbit, say geostationary and beyond? Are there any plans for crewed missions? If so, what would their goals have been?
I'm looking for missions that are either currently in the planning process or were recently considered (say, post Constellation program). I am specifically looking for non-Lunar orbit or landing missions, but I am OK with missions beyond The Moon, say to a Lagrange point.
Edit: I just realized how specific I need to be. I mean a sort of "Earth Neighbourhood" type mission. So not to anywhere, just to space. Thus Mars missions are out.
