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.

The S6 truss segment will be the 11th and final piece of the Station's Integrated Truss Structure and will support the fourth and final set of solar arrays, batteries, and electronics.

On the parking apron of the KSC Shuttle Landing Facility, near the Mate/Demate device (seen in the foreground), the opened nose of the Super Guppy aircraft reveals its cargo, the Integrated Truss Structure S3. It was built by The Boeing Co. After offloading, the S3 will be transported to the Operations and Checkout Building. The second starboard truss segment of the International Space Station, the S3 truss is scheduled to be added to the Station in April 2003

iss069e005734 (April 28, 2023) --- NASA astronaut Stephen Bowen and UAE (United Arab Emirates) astronaut Sultan Alneyadi are pictured in their Extravehicular Mobility Units, or spacesuits, on the International Space Station's starboard truss structure during a spacewalk. The duo would spend seven hours and one minute in the vacuum of space routing cables and installing insulation readying the orbital outpost for its next set of roll-out solar arrays due to be installed after their delivery on the next SpaceX Dragon cargo mission.

KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility, photographers take advantage of a media showcase to get photos of the S3/S4 integrated truss segment. The starboard 3/4 truss segment will launch aboard Space Shuttle Atlantis on mission STS-117, targeted for March 15. The element will be added to the 11-segment integrated truss structure, the station's backbone. The integrated truss structure eventually will span more than 300 feet. The S3/S4 truss has two large solar arrays and will provide one-fourth of the total power generation for the completed station. Photo credit: NASA/George Shelton

KENNEDY SPACE CENTER, FLA. -- As part of the Crew Equipment Interface Test, STS-112 Mission Specialist Piers Sellers (foreground) and Commander Jeffrey Ashby look over the payload for the mission in the Space Station Processing Facility. Mission STS-112 will be ferrying the S1 ITS to the International Space Station on its scheduled Aug. 22 flight. The S1 truss is the first starboard (right-side) truss segment, whose main job is providing structural support for the orbiting research facility's 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

KENNEDY SPACE CENTER, FLA. - STS-116 Mission Specialist Christer Fuglesang (right) (European Space Agency) practices using a tool that is part of the equipment for the mission. He joined STS-118 crew members for the familiarization activities in the Space Station Processing Facility. The STS-116 mission will deliver the third port truss segment, the P5 Truss, to attach to the second port truss segment, the P3/P4 Truss. The STS-118 mission will be delivering and installing the third starboard truss segment, the ITS S5, to the International Space Station, and carry a SPACEHAB Single Cargo Module with supplies and equipment. Launch dates for both missions are under review.

S120-E-007002 (28 Oct. 2007) --- Astronaut Daniel Tani, Expedition 16 flight engineer, participates in the second of five scheduled sessions of extravehicular activity (EVA) as construction continues on the International Space Station. During the 6-hour, 33-minute spacewalk Tani and astronaut Scott Parazynski (out of frame), STS-120 mission specialist, worked in tandem to disconnect cables from the P6 truss, allowing it to be removed from the Z1 truss. Tani also visually inspected the station's starboard Solar Alpha Rotary Joint (SARJ) and gathered samples of "shavings" he found under the joint's multi-layer insulation covers. Also the spacewalkers outfitted the Harmony module, mated the power and data grapple fixture and reconfigured connectors on the starboard 1 (S1) truss that will allow the radiator on S1 to be deployed from the ground later.
