STS-119 Crew Walkout

STS119-S-007 (15 March 2009) --- After suiting up, the STS-119 crewmembers exit the Operations and Checkout Building to board the Astrovan, which will take them to launch pad 39A for the launch of Space Shuttle Discovery on the STS-119 mission. From the left are astronauts John Phillips, Japan Aerospace Exploration Agency’s Koichi Wakata, Steve Swanson, Richard Arnold, all mission specialists; Tony Antonelli, pilot; Joseph Acaba (behind Antonelli), mission specialist; and Lee Archambault, commander. Wakata will join Expedition 18 in progress to serve as a flight engineer aboard the International Space Station. 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.
