Workers unwrap the ExPRESS Logistics Carrier 3 or ELC-3 still nestled in its transportation case.

In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, workers unwrap the ExPRESS Logistics Carrier 3, or ELC-3, still nestled in its transportation case.

ELC-3 and the Alpha Magnetic Spectrometer are the primary payloads for space shuttle Endeavour's STS-134 mission to the International Space Station. The STS-134 crew will also deliver spare parts including two S-band communications antennas, a high pressure gas tank, additional spare parts for Dextre and micrometeoroid debris shields. Endeavour's launch is targeted for July 29, 2010. For information on the STS-134 mission objectives and crew, visit http://www.nasa.gov/shuttle. Photo credit: NASA/Kim Shiflett
