CAPE CANAVERAL, Fla. -- In the Canister Rotation Facility at NASA's Kennedy Space Center in Florida, the payload canister rests on a transport vehicle after being rotated into a vertical position. The canister will then be delivered to Launch Pad 39A, lifted into the rotating service structure where the module will be moved into the clean room before it is 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/Jack Pfaller
