The STS-127 crew members arrive at NASA's Kennedy Space Center in Florida

The STS-127 crew members arrive at NASA's Kennedy Space Center in Florida to prepare for space shuttle Endeavour's July 11 launch on the 29th assembly flight to the International Space Station. Leading the way, Commander Mark Polansky is greeted by the STS-127 Launch Director Pete Nickolenko. Behind Polansky is Pilot Doug Hurley. Polansky will be making his third shuttle flight and Hurley his first. This will be the third launch attempt due to the leak of hydrogen gas at the Ground Umbilical Carrier Plate during tanking on two previous attempts, June 13 and June 17. The STS-127 mission is the final of three flights dedicated to the assembly of the Japan Aerospace Exploration Agency's Kibo laboratory complex. Endeavour will deliver the Japanese Experiment Module's Exposed Facility, or JEM-EF, and the Experiment Logistics Module-Exposed Section, or ELM-ES. Photo credit: NASA/Kim Shiflett
