CAPE CANAVERAL, Fla. -- In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the SEDA-AP (Space Environment Data Acquisition Equipment-Attached Payload) is waiting to be installed on the Japanese Experiment Module's Experiment Logistics Module-Exposed Section, or ELM-ES. The SEDA-AP and ELM-ES are part of space shuttle Endeavour's payload for the STS-127 mission. SEDA-AP will measure space environment in ISS orbit and environmental effects on materials and electronic devices to investigate the interaction with and from the environment at the Kibo exposed facility. Endeavour is targeted to launch May 15. Photo credit: NASA/Troy Cryder
