At NASA's Kennedy Space Center in Florida, space shuttle Endeavour comes to a stop over the flame trench on Launch Pad 39A. First motion of the 3.4-mile rollaround from Launch Pad 39B was at 3:16 a.m. EDT, and the shuttle was secured to Launch Pad 39A at 11:42 a.m. EDT. Endeavour was on standby on Pad 39B to be used in the unlikely event that a rescue mission was necessary during space shuttle Atlantis' STS-125 mission to NASA's Hubble Space Telescope. The payload on Endeavour's next mission, STS-127, includes the Japan Aerospace Exploration Agency's Kibo Exposed Facility and the Experiment Logistics Module Exposed Section of the International Space Station. They will be installed on the Kibo laboratory already on the station. Launch of STS-127 is targeted for June 13. Photo credit: NASA/Kim Shiflett
