CAPE CANAVERAL, Fla. – Viewed across the Indian River Lagoon, space shuttle Endeavour waits for launch after rollback of the rotating service structure, or RSS, at left. First motion of the RSS was at 10:15 a.m. EDT. At far right is the tank that holds 300,000 gallons of water used for sound suppression during liftoff. First motion of the RSS was at 10:15 a.m. EDT. The rollback is in preparation for Endeavour's liftoff on the STS-127 mission with a crew of seven. This is the second launch attempt for Endeavour after the June 13 launch was scrubbed due to a hydrogen leak at the Ground Umbilical Carrier Plate during tanking June 12. The launch will be Endeavour's 23rd flight. The shuttle will carry the Japanese Experiment Module's Exposed Facility, or JEM-EF, and the Experiment Logistics Module-Exposed Section, or ELM-ES, on STS-127. The mission is the final of three flights dedicated to the assembly of the Japan Aerospace Exploration Agency's Kibo laboratory complex on the space station. Endeavour's launch is scheduled for June 17 at 5:40 a.m. EDT. Photo credit: NASA/Kim Shiflett
