R2 to board the ISS "Astronauts on board the International Space Station will soon have a new roommate--and it's not human. It's a humanoid. In Sept. 2010, space shuttle Discovery will deliver Robonaut 2--"R2" for short--to the ISS, where it will become the first humanoid robot to travel and work in space. Developed jointly by NASA and General Motors, R2 looks a bit like C-3PO of Star Wars fame but lacks the chatty robot's gift of gab. That's okay, because the humans on board need a worker that can wield more useful tools than a sharp tongue."
