True: R2 Tweets from Outer Space! OK, it's NASA's R2, Not the One from Star Wars

R2 poses with astronaut Catherine Coleman (of Shelburne, Mass.)

C3PO was nowhere to be seen, but R2 is on the job.

The crew of the International Space Station on Monday activated Robonaut 2, the "automoton astronaut."

"Those electrons feel GOOD!"  read a post on Robonaut 2's Twitter page. "One small step for man, one giant leap for tinman kind."
