CAPE CANAVERAL, Fla. -- In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, workers prepare the Heat Rejection Subsystem, or HRS, radiator for installation onto the Express Logistics Carrier-4, or ELC-4. Space shuttle Discovery and its STS-133 crew will deliver the ELC-4 filled with external payloads and experiments, as well as the spare radiator and the Permanent Multipurpose Module, or PMM, to the International Space Station. Launch is targeted for Nov. 1 at 4:33 p.m. EDT. For more information visit, www.nasa.gov_shuttle. Photo credit: NASA_Troy Cryder

CAPE CANAVERAL, Fla. -- In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, workers prepare a resupply stowage platform prior to installation of cargo headed to the International Space Station. The stowage platforms will then be moved into the Permanent Multipurpose Module, or PMM. The PMM will be used to carry supplies and critical spare parts to the station. The module will be left behind so it can be used for microgravity experiments in fluid physics, materials science, biology and biotechnology. Space shuttle Discovery will deliver its payload to the station on the STS-133 mission. Launch is targeted for Nov. 1 at 4:33 p.m. EDT. Photo credit: NASA_Jack Pfaller
