Commander Brent Jett (center) talks with employees and visitors at NASA Stennis Space Center. The astronauts of NASA's STS-115 space shuttle mission visited SSC in south Mississippi to share highlights of their 12-day mission and to thank SSC employees for the reliability of the space shuttle's main engines, which helped propel Space Shuttle Atlantis into orbit. STS-115's other crewmembers are (from left) Mission Specialists Joe Tanner, Dan Burbank, Heidemarie Stefanyshyn-Piper and Steve MacLean of the Canadian Space Agency. The mission launched Sept. 9, 2006, resuming construction of the International Space Station.

KENNEDY SPACE CENTER, FLA. - The STS-115 crew members stride out of the Operations and Checkout Building eager to get to Launch Pad 39B and the start of their mission to the International Space Station. This is the second attempt at launch after a week's postponement due to weather and technical concerns. On the left side, front to back, are Pilot Christopher Ferguson and Mission Specialists Steven MacLean and Heidemarie Stefanyshyn-Piper. On the right side, front to back, are Commander Brent Jett and Mission Specialists Daniel Burbank and Joseph Tanner. On its second attempt for launch, Atlantis is scheduled to lift off at 11:41 a.m. EDT today from Launch Pad 39B. During the STS-115 mission, Atlantis' astronauts will deliver and install the 17.5-ton, bus-sized P3/P4 integrated truss segment on the station. The girder-like truss includes a set of giant solar arrays, batteries and associated electronics and will provide one-fourth of the total power-generation capability for the completed station. This mission is the 116th space shuttle flight, the 27th flight for orbiter Atlantis, and the 19th U.S. flight to the ISS. STS-115 is scheduled to last 11 days with a planned landing at KSC.

KENNEDY SPACE CENTER, FLA. - The crew of mission STS-115 stop to talk to the media after arriving at NASA Kennedy Space Center's Shuttle Landing Facility to prepare for a second launch attempt on Sept. 6 to the International Space Station. Seen here is Mission Specialist Steven MacLean, who will be making his second flight on the shuttle. MacLean is with the Canadian Space Agency. Mission managers cancelled Atlantis' first launch campaign due to a lightning strike at the pad and the passage of Tropical Storm Ernesto along Florida's east coast. The mission will deliver and install the 17-and-a-half-ton P3/P4 truss segment to the port side of the integrated truss system on the orbital outpost. The truss includes a new set of photovoltaic solar arrays. When unfurled to their full length of 240 feet, the arrays will provide additional power for the station in preparation for the delivery of international science modules over the next two years. STS-115 is expected to last 11 days and includes three scheduled spacewalks. Photo credit: NASA/Kim Shiflett

JSC2006-E-41540 (22 Sept. 2006) --- The astronauts who yesterday completed the successful STS-115 mission are pictured on a dais in a hangar at Ellington Field after returning to Houston from the Kennedy Space Center, site of the Sept. 21 landing of the Space Shuttle Atlantis. JSC Director Michael Coats addresses the crowd on hand for the event. Seated, from left, are astronauts Brent W. Jett Jr., commander; Christopher J. Ferguson, pilot; Joseph R. Tanner, Daniel C. Burbank, Heidemarie M. Stefanyshyn-Piper, and the Canadian Space Agency's Steven G. MacLean, all mission specialists.

This is the STS-115 insignia. This mission continued the assembly of the International Space Station (ISS) with the installation of the truss segments P3 and P4. Following the installation of the segments utilizing both the shuttle and the station robotic arms, a series of three space walks completed the final connections and prepared for the deployment of the station's second set of solar arrays. To reflect the primary mission of the flight, the patch depicts a solar panel as the main element. As the Space Shuttle Atlantis launches towards the ISS, its trail depicts the symbol of the Astronaut Office. The star burst, representing the power of the sun, rises over the Earth and shines on the solar panel. The shuttle flight number 115 is shown at the bottom of the patch, along with the ISS assembly designation 12A (the 12th American assembly mission). The blue Earth in the background reminds us of the importance of space exploration and research to all of Earth's inhabitants.
