Discovery shuttle lands

[Auntie]

Discovery shuttle finally landed. What I wonder is... what exactly do they do up there in space? Does anyone here find it strange that they never talk about what they do up there? My opinion is, they're obviously are looking for trouble and are doing something that they shouldn't be doing.

Okay this is the second time you've said that. What do you think they are doing? Watch the NASA channel if you want to see what they do up there.
