At the turn basin at NASA's Kennedy Space Center in Florida, external fuel tank ET-131 is moved out of the Pegasus barge. The tank, which will be used on the STS-127 mission, will be transported to a high bay in the Vehicle Assembly Building for checkout. The Japanese Experiment Module's Experiment Logistics Module-Exposed Section, or ELM-ES, is part of the payload on the STS-127 mission, targeted for launch in June. Photo credit: NASA/Tim Jacobs
