The ISS supposedly was to do science. This is the major science module. There are some experiment bays already up there although we don't hear much about them.
Oh, so it will "do" science?
Well, that's pretty general, don't ya think?
I can "do" science right here in my basement.
I want to buy me a muffle furnace, but I might
have to add a new breaker to the box for it.
Then I can do me some some "real" science.
