In the Space Station Processing Facility, a crane moves the Lightweight Multi-Purpose Experiment Support Structure Carrier (LMC) toward a payload canister, doors open to receive it. Slated to fly on space shuttle mission STS-121, the LMC is ready to be delivered to Launch Pad 39B for installation into orbiter Discovery. It is a cross-bay carrier for hardware required to perform development test objective 848. Test objective 848 is a demonstration of the tools and techniques developed to repair damaged orbiter thermal protection system tiles during a spacewalk, or extravehicular activity. The target launch window for STS-121 is July 1 to July 19, 2006. Photo credit: NASA/Cory Husten
