Harmony, also known as Node 2, is a module of the International Space Station (ISS) that serves as its "utility hub". It connects the laboratory modules of the United States, Europe and Japan, while also providing electrical power and data. The module also has sleeping cabins for four astronauts.
Harmony has six Common Berthing Mechanism (CBM) ports. It is attached to Destiny at its aft port, with Columbus to starboard and Kibō to port. Its forward and zenith ports are each equipped with a Pressurized Mating Adapter (PMA) and International Docking Adapter (IDA) for docking visiting spacecraft. The nadir CBM, the only one without permanently mounted equipment, is typically used for berthing cargo spacecraft.
Harmony was launched aboard STS-120 on October 23, 2007. It was first attached temporarily to the port side of the Unity module before being moved to its permanent location on the forward end of Destiny on November 14, 2007. The module added 70 m3 (2,500 cu ft) of habitable volume to the station, increasing its living space by nearly 20%, from 420 to 490 m3 (15,000 to 17,000 cu ft).
