Astronauts Piers J. Sellers (left ) and David A. Wolf work on the newly installed Starboard One (S1) truss to the International Space Station (ISS) during the STS-112 mission. 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.

This image of the International Space Station (ISS) was photographed by one of the crewmembers of the STS-112 mission following separation from the Space Shuttle Orbiter Atlantis as the orbiter pulled away from the ISS. The primary payloads of this mission, International Space Station 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.

STS-102 mission astronaut Susan J. Helms translates along the longerons of the Space Shuttle Discovery during the first of two space walks. During this walk, the Pressurized Mating Adapter 3 was prepared for repositioning from the Unity Module's Earth-facing berth to its port-side berth to make room for the Leonardo multipurpose Logistics Module (MPLM), supplied by the Italian Space Agency. The Leonardo MPLM is the first of three such pressurized modules that will serve as the International Space Station's (ISS') moving vans, carrying laboratory racks filled with equipment, experiments, and supplies to and from the Station aboard the Space Shuttle. The cylindrical module is approximately 21-feet long and 15- feet in diameter, weighing almost 4.5 tons. It can carry up to 10 tons of cargo in 16 standard Space Station equipment racks. Of the 16 racks the module can carry, 5 can be furnished with power, data, and fluid to support refrigerators or freezers. In order to function as an attached station module as well as a cargo transport, the logistics module also includes components that provide life support, fire detection and suppression, electrical distribution, and computer functions. NASA's 103rd overall mission and the 8th Space Station Assembly Flight, STS-102 mission also served as a crew rotation flight. It delivered the Expedition Two crew to the Station and returned the Expedition One crew back to Earth.

CAPE CANAVERAL, Fla. - At Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-132 Mission Specialist Piers Sellers participates in a question-and-answer session with media representatives. The crew is at Kennedy for their Terminal Countdown Demonstration Test, or TCDT, a dress rehearsal for launch. TCDT provides each shuttle crew and launch team the opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency training. On the STS-132 mission, the six-member crew will deliver an Integrated Cargo Carrier, or ICC, and the Russian-built Mini-Research Module-1, or MRM-1, to the International Space Station aboard space shuttle Atlantis. The ICC is an unpressurized flat bed pallet and keel yoke assembly used to support the transfer of exterior cargo from the shuttle to the space station. The MRM-1, known as Rassvet, is the second in a series of new pressurized components for Russia and will be permanently attached to the Earth-facing port of the Zarya control module. Rassvet, which translates to 'dawn,' will be used for cargo storage and will provide an additional docking port to the station. STS-132 is the 34th mission to the station and the 132nd shuttle mission overall. Atlantis is targeted to launch on May 14 at 2:19 p.m. For information on the STS-132 mission, visit http:__www.nasa.gov_mission_pages_shuttle_shuttlemissions_sts132_index.html.

The crew is at Kennedy for their Terminal Countdown Demonstration Test, or TCDT, a dress rehearsal for launch. TCDT provides each shuttle crew and launch team the opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency training. On the STS-132 mission, the six-member crew will deliver an Integrated Cargo Carrier, or ICC, and the Russian-built Mini-Research Module-1, or MRM-1, to the International Space Station aboard space shuttle Atlantis. The ICC is an unpressurized flat bed pallet and keel yoke assembly used to support the transfer of exterior cargo from the shuttle to the space station. The MRM-1, known as Rassvet, is the second in a series of new pressurized components for Russia and will be permanently attached to the Earth-facing port of the Zarya control module. Rassvet, which translates to 'dawn,' will be used for cargo storage and will provide an additional docking port to the station. STS-132 is the 34th mission to the station and the 132nd shuttle mission overall. Atlantis is targeted to launch on May 14 at 2:19 p.m. For information on the STS-132 mission, visit http:__www.nasa.gov_mission_pages_shuttle_shuttlemissions_sts132_index.html.

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.
