KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility at NASA's Kennedy Space Center, the Special Purpose Dexterous Manipulator, known as Dextre, moves across the facility via an overhead crane to the payload canister at right for transfer to Launch Pad 39A. Dextre is a sophisticated dual-armed robot, which is part of Canada's contribution to the International Space Station. Along with Canadarm2, which is called the Space Station Remote Manipulator System, and a moveable work platform called the Mobile Base System, these three elements form a robotic system called the Mobile Servicing System. The three components have been designed to work together or independently. Dextre is part of the payload on space shuttle Endeavour's STS-123 mission, targeted for launch March 11.
