What would we even do up there? o_O I mean, there's no real need to make up a new planet for the change of scenery, if that's why people want it.

I can see space being an interesting environment if we were exploring a space station, or some "ruins" (moon base? whatever you wanna call it. . . .) in space suits. And then we stumble upon an artefact that proves to be a source of evil space monsters that have a habit of incubating in our bellies!!!
