Workers in the Space Station Processing Facility attach an overhead crane to the Canadian Space Agencys Space Station Remote Manipulator System (SSRMS). The crane will lift and transfer the SSRMS to a test stand where it will be mated to its payload carrier. This pallet will later be installed into the payload bay of Space Shuttle Endeavour for launch to the International Space Station on STS-100 in April 2001. The 56-foot-long arm will be the primary means of transferring payloads between the orbiter payload bay and the Station. Its three segments comprise seven joints for highly flexible land precise movement, making it capable of moving around the Stations exterior like an inchworm
