A tracking camera on Launch Pad 39B of the Kennedy Space Center in Florida captures the flames of Space Shuttle Atlantis' three main engines as the Orbiter hurdles into space on mission STS-112. Liftoff occurred at 3:46 pm EDT, October 7, 2002. Atlantis carried the Starboard-1 (S1) Integrated Truss Structure and the Crew and Equipment Translation Aid (CETA) Cart A. The S1 was the second truss structure installed on the International Space Station (ISS). It was attached to the S0 truss which was previously installed by the STS-110 mission. The CETA is the first of two human-powered carts that ride along the ISS railway, providing mobile work platforms for future space walking astronauts. The 11 day mission performed three space walks to attach the S1 truss.

KENNEDY SPACE CENTER, FLA. - During a Crew Equipment Interface Test, STS-112 Mission Specialist Piers Sellers looks at the engine on Atlantis, the designated orbiter for the mission. On the 15th assembly flight to the International Space Station, Atlantis and crew will be ferrying the S1 Integrated Truss Structure. The S1 truss is the first starboard (right-side) truss segment, whose main job is providing structural support for the radiator panels that cool the Space Station's complex power system. The S1 truss segment also will house communications systems, external experiment positions and other subsystems. The S1 truss will be attached to the S0 truss. STS-112 is currently scheduled for launch Aug. 22, 2002

KENNEDY SPACE CENTER, FLA. -- Workers perform post-polishing inspection on Atlantis' flow liners. Following an extensive investigation into the cause of tiny cracks inside fuel lines of the four space shuttle orbiters, a welding and polishing process is being implemented that will restore flow-liner integrity to design condition. These liners are inside the space shuttle Main Propulsion System fuel lines to preclude liquid hydrogen and oxygen turbulent flow into the engines during launch and climb to orbit. The technique calls for welds of three very small cracks on Atlantis and two on Endeavour. Additionally, the microscopic rough edges of the liner holes are being smoothed by polishing to reduce the chance of more cracks developing in the future. Atlantis is scheduled on mission STS-112, an assembly flight to the International Space Station, no earlier than Sept. 28, 2002.

Being attached to the Canadarm2 on the International Space Station (ISS), the Remote Manipulator System arm built by the Canadian Space Agency, the Integrated Truss Assembly (S1) Truss is suspended over the Space Shuttle Orbiter Atlantis' cargo bay. Astronauts Sandra H. Magnus, STS-112 mission specialist, and Peggy A. Whitson, Expedition Five flight engineer, used the Canadarm2 from inside the Destiny laboratory on the ISS to lift the S1 truss out of the orbiter's cargo bay and move it into position prior to its installation on the ISS. The primary payloads of this mission, ISS Assembly Mission 9A, were the Integrated Truss Assembly S1 (S One), the starboard side thermal radiator truss, and the Crew Equipment Translation Aid (CETA) cart to the ISS. The S1 truss provides structural support for the orbiting research facility's radiator panels, which use ammonia to cool the Station's complex power system. The S1 truss was attached to the S0 (S Zero) truss, which was launched on April 8, 2002 aboard the STS-110, and flows 637 pounds of anhydrous ammonia through three heat-rejection radiators. The truss is 45-feet long, 15-feet wide, 10-feet tall, and weighs approximately 32,000 pounds. The CETA cart was attached to the Mobil Transporter and will be used by assembly crews on later missions. Manufactured by the Boeing Company in Huntington Beach, California, the truss primary structure was transferred to the Marshall Space Flight Center in February 1999 for hardware installations and manufacturing acceptance testing. The launch of the STS-112 mission occurred on October 7, 2002, and its 11-day mission ended on October 18, 2002.
