STS-119
S6 Truss and Completion of the Original U.S. Solar-Array Architecture
STS-119 delivered the S6 truss and the fourth U.S. solar-array set, completing the station's original main truss-mounted photovoltaic configuration.

Objective
What this ISS mission set out to accomplish
Complete the station's original U.S. photovoltaic truss architecture by adding the outer starboard S6 segment and its solar-array wing pair.
This record treats STS-119 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-119 launched on March 15, 2009 using Space Shuttle Discovery from Kennedy Space Center, Launch Pad 39A.
Discovery carried S6 to the station for robotic transfer and attachment. Spacewalkers connected the segment and prepared the solar arrays, batteries, and associated power hardware for activation.
Hardware and assembly
What was delivered, installed, or reconfigured
Primary hardware or assembly focus: S6 Truss Segment, solar arrays, batteries, power hardware.
Installation record: S6 installed and arrays deployed during STS-119. This is the engineering connection between the mission story and the interactive International Space Station breakdown.
Outcome
What changed on the International Space Station
The mission brought the station to its planned full original U.S. solar-array configuration and completed the principal truss assembly sequence begun years earlier.
The documented result makes STS-119 part of the larger ISS assembly chain, where individual missions progressively added structure, power, laboratories, robotics, thermal control, logistics, and crew-support systems.
