Description:

• “Harmony“ is an aluminum node (Node 2) 7.2 meters long and 4.4 meters in diameter that provides a passageway between four station science experiment facilities: the U.S. Destiny Laboratory, the Kibo Japanese Experiment Module, the European Columbus Laboratory and the Centrifuge Accommodation Module. It also provides connecting ports for Multi-Purpose Logistics Modules, the Japanese HTV and the Pressurized Mating Adapter 2 to which Space Shuttles dock. Its pressurized volume is 70 cubic meters, and its launch weight is approximately 13,600 kilograms.
• It was built by Alenia Spazio under contract of the Italian Space Agency. It was built for NASA under a barter agreement with the European Space Agency in exchange for the launch of the European Columbus Laboratory. The installation of Node 2 denotes the U.S. Core Complete stage of International Space Station assembly and increases the living and working space inside the station to approximately 500 cubic meters.

Mission details:

• Harmony was installed on Node-1 Unity on 26 October 2007 at 15h38 UTC.
