Under a cloud-washed sky, spectators watch as space shuttle Endeavour rises majestically from Launch Pad 39A at NASA's Kennedy Space Center in Florida on the STS-127 mission to the International Space Station. Liftoff was at 6:03 p.m. EDT on July 15, 2009, and was the sixth launch attempt for the mission. The launch was scrubbed on June 13 and June 17 when a hydrogen gas leak occurred during tanking due to a misaligned ground umbilical carrier plate. The mission was postponed July 11, 12 and 13 due to weather conditions near the Shuttle Landing Facility at Kennedy that violated rules for launching, and lightning issues.
