STS-112
S1 Truss, Thermal Control and the Starboard Backbone
STS-112 delivered the S1 truss, expanding the station's starboard structure and adding thermal-control equipment plus a Crew and Equipment Translation Aid cart.

Objective
What this ISS mission set out to accomplish
Extend the station's truss to starboard and add cooling, utility, translation, and structural systems required for later power-generation segments.
This record treats STS-112 as an assembly or station-support mission rather than as a satellite engineering page, keeping the mission objective separate from the hardware-level ISS engineering record.
Flight and rendezvous
How the mission reached and worked at the station
STS-112 launched on October 7, 2002 using Space Shuttle Atlantis from Kennedy Space Center, Launch Pad 39B.
The S1 truss was transferred to the station and attached to S0. Spacewalkers connected electrical and ammonia cooling lines, released launch restraints, and outfitted the CETA system and other external hardware.
Hardware and assembly
What was delivered, installed, or reconfigured
Primary hardware or assembly focus: S1 Integrated Truss Segment and CETA Cart A.
Installation record: S1 installed during the October 2002 docked mission. This is the engineering connection between the mission story and the interactive International Space Station breakdown.
Outcome
What changed on the International Space Station
S1 became a permanent part of the Integrated Truss Structure and added key elements of the station's external active thermal-control architecture.
The documented result makes STS-112 part of the larger ISS assembly chain, where individual missions progressively added structure, power, laboratories, robotics, thermal control, logistics, and crew-support systems.
