Yes, it will do science. Several kinds actually. Too bad the ISS crew is limited to three, which is maybe 1/2 a tech, because they could use three full-time techs up there once the science modules are up and running.
But Righty,
(you don't mind if I call you "Righty", do you?)
tell me, please, what does all that really mean?
What will we r-e-a-l-l-y learn from spending all those space $$$?
After all, "my" science involves a muffle furnace and my daughter-in-law's bitch-from-hell-she-cat ... and that's all I'm willing to say about it at the present time.
