Atlantis and Crew on Deck for STS-115
STS-115 Commander Brent Jett Even as Discovery stands poised for liftoff on Launch Pad 39B, the crew for the following mission, STS-115 on Space Shuttle Atlantis, arrived at NASA's Kennedy Space Center for the three-day crew equipment interface test that is part of their training. Before every mission, each crew spends time at Kennedy working with the actual payloads and orbiter they will take into space.

Mission Commander Brent Jett, a veteran of three space missions, will lead the STS-115 crew on the 19th mission to the International Space Station.

The crew of Atlantis is scheduled to deliver and install the P3/P4 truss segment along with solar array set 2A and 4A and batteries to continue constructing the station.

Joining Jett on the mission are three other space shuttle veterans -- Mission Specialists Joe Tanner, Dan Burbank, and Steve MacLean. Rounding out the crew are Pilot Chris Ferguson and Mission Specialist Heidemarie Stefanyshyn-Piper, both making their first space flight.

Mission Specialists Joseph Tanner, Steven MacLean, and Heidemarie Stefanyshyn-Piper. The orbiter Atlantis, which lifted off on its maiden voyage on Oct. 3, 1985, will make its 27th trip to space. Atlantis last flew in October 2002 for STS-112, when it delivered the S1 integrated truss segment to the space station. The vehicle has also delivered several other vital components to the station, including the U.S. Destiny Laboratory and the Quest Joint Airlock modules.

STS-115 will mark the return to construction of the station, the main goal of the remaining space shuttle flights. The P3/P4 segments -- which are approximately 45.3 feet long -- will attach to the P1 truss on the port side of the station's integrated truss segment. Once in place, the addition of the P3/P4 trusses with their two large solar arrays will provide one-fourth of the total power-generation capability of the completed station.
