In the Operations and Checkout Building at NASA's Kennedy Space Center in Florida, STS-119 Mission Specialist John Phillips has a final fitting of his launch and entry suit and the helmet. Phillips is making his third shuttle flight. The 14-day 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. Liftoff of Discovery is scheduled for 9:20 p.m. EDT on March 11.
