In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, technicians guide the Permanent Multipurpose Module, or PMM, as an overhead crane lowers it into the payload canister.

The canister will then be transported to Launch Pad 39A and installed into space shuttle Discovery's payload bay. Discovery and its STS-133 crew will deliver the PMM, packed with supplies and critical spare parts, as well as Robonaut 2, the dexterous humanoid astronaut helper, to the International Space Station. Launch is targeted for 4:40 p.m. EDT, Nov. 1. Photo credit: NASA/Cory Huston
