At NASA's Kennedy Space Center finds space shuttle Endeavour departing Launch Pad 39B on its rollaround to Launch Pad 39A.

Early morning at NASA's Kennedy Space Center in Florida finds space shuttle Endeavour departing Launch Pad 39B on its 3.4-mile rollaround to Launch Pad 39A. First motion was at 3:16 a.m. EDT. Three lightning towers have been erected already on Pad 39B, at right, to support the new launch vehicles in NASA's Constellation Program. 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 the STS-127 mission 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
