CAPE CANAVERAL, Fla. – In the Operations and Checkout Building at NASA's Kennedy Space Center in Florida, STS-119 Mission Specialist Joseph Acaba is helped putting on his boots with his launch-and-entry suit. The crew will be heading for Launch Pad 39A and liftoff of space shuttle Discovery, scheduled for 7:43 p.m. EDT on March 15. An earlier launch attempt March 11 was scrubbed at 2:36 p.m. due to a gaseous hydrogen leak from the external tank at the Ground Umbilical Carrier Plate during tanking. A seven-inch quick disconnect and two seals were replaced. The STS-119 mission is the 28th to the International Space Station and the 125th space shuttle flight. Discovery will deliver the final pair of power-generating solar array wings and the S6 truss segment. Installation of S6 will signal the station's readiness to house a six-member crew for conducting increased science. Photo credit: NASA/Kim Shiflett
