At NASA's Kennedy Space Center in Florida, technicians prepare a working model of the dexterous humanoid astronaut helper, Robonaut 2, for the media to check out before space shuttle Discovery's final flight on the STS-133 mission.

Discovery and its six-member crew will deliver the Permanent Multipurpose Module, packed with supplies and critical spare parts, as well as Robonaut 2 to the International Space Station.
