STS-120 was a space shuttle mission to the International Space Station (ISS) that launched on 23 October 2007 from the Kennedy Space Center, Florida. The mission is also referred to as ISS-10A by the ISS program. STS-120 delivered the Harmony module and reconfigured a portion of the station in preparation for future assembly missions. STS-120 was flown by Space Shuttle Discovery, and was the twenty-third space shuttle mission to the ISS.

The STS-120 patch reflects the role of the mission in the future of the space program. The shuttle payload bay carries Node 2, the doorway to the future international laboratory elements on the International Space Station. On the left the star represents the International Space Station; the red colored points represent the current location of the P6 solar array, furled and awaiting relocation when the crew arrives. During the mission, the crew will move P6 to its final home at the end of the port truss. The gold points represent the P6 solar array in its new location, unfurled and producing power for science and life support. On the right, the moon and Mars can be seen representing the future of NASA. The constellation Orion rises in the background, symbolizing NASA's new exploration vehicle. Through all, the shuttle rises up and away, leading the way to the future. 

Harmony, also known as Node 2, is the "utility hub" of the International Space Station. The hub contains four racks that provide electrical power, plus electronic data, and act as a central connecting point for several other components via its six Common Berthing Mechanisms (CBMs). Harmony added 2,666 cubic feet (75.5 m3) to the station's living volume, an increase of almost 20 percent, from 15,000 cu ft (420 m3) to 17,666 cu ft (500.2 m3) The successful installation of Harmony meant that from NASA's perspective, the station was "U.S. Core Complete". Harmony was successfully launched into space aboard Space Shuttle flight STS-120 on October 23, 2007. After temporarily being attached to the port side of the Unity node, it was moved to its permanent location on the forward end of the Destiny laboratory on November 14, 2007.
