At NASA's Kennedy Space Center in Florida, external fuel tank ET-131 moves toward the Vehicle Assembly Building. The tank, which will be used on the STS-127 mission, will be moved to a high bay 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
