STS-120
Harmony Node, P6 Relocation and a Difficult Solar-Array Repair
STS-120 delivered Harmony, temporarily attached the new node to the station, relocated the P6 truss to its permanent port-side position, and repaired a torn solar array during deployment.

Objective
What this ISS mission set out to accomplish
Deliver Harmony to prepare the ISS for the European Columbus and Japanese Kibo laboratories and move P6 from its temporary location to the end of the port truss.
This record treats STS-120 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-120 launched on October 23, 2007 using Space Shuttle Discovery from Kennedy Space Center, Launch Pad 39A.
Discovery carried Harmony while station robotics moved the node into a temporary location. The mission also used complex robotic and EVA operations to relocate P6; astronauts later repaired a damaged solar array during redeployment.
Hardware and assembly
What was delivered, installed, or reconfigured
Primary hardware or assembly focus: Harmony (Node 2) and P6 truss relocation operations.
Installation record: Harmony was temporarily installed during STS-120 before later relocation to its permanent position. This is the engineering connection between the mission story and the interactive International Space Station breakdown.
Outcome
What changed on the International Space Station
Harmony arrived safely and later became the connecting hub for Destiny, Columbus, Kibo, and commercial crew docking interfaces. P6 reached its permanent position and its damaged array was successfully repaired.
The documented result makes STS-120 part of the larger ISS assembly chain, where individual missions progressively added structure, power, laboratories, robotics, thermal control, logistics, and crew-support systems.
