Inside the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the hatch of the Permanent Multipurpose Module (PMM) is closed in preparation for space shuttle Discovery's STS-133 mission to the International Space Station.
Robonaut 2 (R2) and critical spare parts are packed inside the PMM, which will be left aboard the station on Discovery's final mission. Targeted to launch Nov. 1 at 4:40 p.m. EDT, Discovery and its crew also will carry Express Logistics Carrier-4 (ELC-4), which is filled with external payloads and experiments.
