In the Firing Room at NASA's Kennedy Space Center in Florida, STS-127 Shuttle Launch Director Pete Nickolenko (right) congratulates the mission team for the successful launch of space shuttle Endeavour on the STS-127 mission. Liftoff was on-time at 6:03 p.m. EDT. At left are Endeavour Flow Director Dana Hutcherson and Shuttle Launch Director Mike Leinbach. Today was the sixth launch attempt for the STS-127 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. Endeavour will deliver the Japanese Experiment Module's Exposed Facility and the Experiment Logistics Module-Exposed Section in the final of three flights dedicated to the assembly of the Japan Aerospace Exploration Agency's Kibo laboratory complex on the International Space Station.
