In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, Jason Rhian with Spacevidcast, enthusiastically shakes the hand of Robonaut (R2) during a media event hosted by NASA.

R2 will fly to the International Space Station aboard space shuttle Discovery on the STS-133 mission. Although it will initially only participate in operational tests, upgrades could eventually allow the robot to realize its true purpose -- helping spacewalking astronauts with tasks outside the space station.
