Harmony (ISS Module)
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.

Famous quotes containing the word harmony:
“A villain must be a thing of power, handled with delicacy and grace. He must be wicked enough to excite our aversion, strong enough to arouse our fear, human enough to awaken some transient gleam of sympathy. We must triumph in his downfall, yet not barbarously nor with contempt, and the close of his career must be in harmony with all its previous development.”
—Agnes Repplier (1858–1950)
