In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, workers attach an overhead crane to the Lightweight Multi-Purpose Experiment Support Structure Carrier, or LMC, which holds an ammonia tank assembly. Part of the payload for space shuttle Discovery's STS-128 mission to the International Space Station, the carrier will be weighed and then installed in the payload canister. The STS-128 flight also will carry science and storage racks to the space station on Discovery. Launch of Discovery is targeted for Aug. 18. Photo credit: NASA/Tim Jacobs
