STS-117
S3/S4 Truss and a Third Major Solar-Array Set
STS-117 installed the S3/S4 truss and deployed a new starboard photovoltaic array set while reconfiguring older P6 power hardware.
Mission type
Crewed Space Shuttle assembly mission

Launch vehicle / spacecraft
Space Shuttle Atlantis
Objective
What this ISS mission set out to accomplish
Extend the starboard truss, add another major photovoltaic power channel, and continue the electrical reconfiguration needed for the station's completed power architecture.
This record treats STS-117 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-117 launched on June 8, 2007 using Space Shuttle Atlantis from Kennedy Space Center, Launch Pad 39A.
The S3/S4 assembly included structural truss sections, the Solar Alpha Rotary Joint, photovoltaic radiator hardware, and deployable solar wings. Spacewalkers released launch restraints and assisted array and power-system configuration.
Hardware and assembly
What was delivered, installed, or reconfigured
Primary hardware or assembly focus: S3/S4 truss, Solar Alpha Rotary Joint, photovoltaic arrays.
Installation record: S3/S4 installed during STS-117. This is the engineering connection between the mission story and the interactive International Space Station breakdown.
Outcome
What changed on the International Space Station
STS-117 substantially increased starboard-side power generation and moved the station closer to its final symmetric truss-and-array configuration.
The documented result makes STS-117 part of the larger ISS assembly chain, where individual missions progressively added structure, power, laboratories, robotics, thermal control, logistics, and crew-support systems.
