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. - Huge clouds roll over Launch Pad 39B where Space Shuttle Atlantis still sits after the scrub of its launch on mission STS-115. Atlantis was originally scheduled to launch at 12:29 p.m. EDT on this date, but a 24-hour scrub was called by mission managers due to a concern with fuel cell 1. Towering above the shuttle is the 80-foot lightning mast. At left is the rolled-back rotating service structure with the payload changeout room open. Just above the orange external tank is the vent hood (known as the "beanie cap") at the end of the gaseous oxygen vent arm. Vapors are created as the liquid oxygen in the external tank boil off. The hood vents the gaseous oxygen vapors away from the space shuttle vehicle.

KENNEDY SPACE CENTER, FLA. - After rollback of the rotating service structure on Launch Pad 39B, Space Shuttle Atlantis is revealed. The RSS provides protected access to the orbiter for changeout and servicing of payloads at the pad and then is rolled away before liftoff. Seen above the golden external tank is the vent hood (known as the "beanie cap") at the end of the gaseous oxygen vent arm. Vapors are created as the liquid oxygen in the external tank boil off. The hood vents the gaseous oxygen vapors away from the space shuttle vehicle. Below it, extending from the fixed service structure, is the orbiter access arm with the White Room at the end. The White Room provides entry into the orbiter. Atlantis is scheduled to launch Sept. 6 at 12:29 p.m. EDT on mission STS-115. During the 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 International Space Station. STS-115 is scheduled to last 11 days with a planned KSC landing at about 8:03 a.m. EDT on Sept. 17. Photo credit: NASA/George Shelton KSC-06pd2040

KENNEDY SPACE CENTER, FLA. - Space Shuttle Atlantis is bathed in light on Launch Pad 39B. Atlantis was originally scheduled to launch at 12:29 p.m. EDT on this date, but a 24-hour scrub was called by mission managers due to a concern with Fuel Cell 1. Seen poised above the orange external tank is the vent hood (known as the "beanie cap") at the end of the gaseous oxygen vent arm. Vapors are created as the liquid oxygen in the external tank boil off. The hood vents the gaseous oxygen vapors away from the space shuttle vehicle.

KENNEDY SPACE CENTER, FLA. - After a week's delay of launching due to weather and technical issues, the crew of mission STS-115 have had the traditional breakfast before their third attempt to launch on Space Shuttle Atlantis. Seated left to right are Mission Specialists Heidemarie Stefanyshyn-Piper and Joseph Tanner, Commander Brent Jett, Pilot Christopher Ferguson and Mission Specialists Steven MacLean and Daniel Burbank. MacLean is with the Canadian Space Agency. The launch attempt on Sept. 8 was scrubbed due to an issue with a fuel cut-off sensor system inside the external fuel tank. This is one of several systems that protect the shuttle's main engines by triggering their shutdown if fuel runs unexpectedly low. Following the breakfast, the crew will don their launch suits before heading to 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. STS-115 is scheduled to last 11 days with a planned landing at KSC KSC-06pp2156

KENNEDY SPACE CENTER, FLA. - The STS-115 mission crew happily heads to the Astrovan for the ride to Launch Pad 39B and another attempt at liftoff. From the left, in the back row are Mission Specialists Heidemarie Stefanyshyn-Piper and Joseph Tanner; in the center row are Mission Specialists Steven MacLean and Daniel Burbank; in the front row leading the way are Pilot Christopher Ferguson and Commander Brent Jett. The launch attempt on Sept. 8 was scrubbed due to an issue with a fuel cut-off sensor system inside the external fuel tank. This is one of several systems that protect the shuttle's main engines by triggering their shutdown if fuel runs unexpectedly low.
