In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the dexterous humanoid astronaut helper, Robonaut 2, or R2, is prepared for its lift and installation in a launch box called SLEEPR, or Structural Launch Enclosure to Effectively Protect Robonaut.

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.
