The Node-2 connecting module

The Node-2 connecting module for the International Space Station. 

Node-2 is a pressurised module which serves as a connecting passage between the European Columbus laboratory, the US laboratory Destiny and the Japanese laboratory Kibo.

Node-2 also provides a docking port for the discontinued Space Shuttle and the Japanese HII transfer vehicle, while it also served as an attachment point for the Multi-Purpose Logistics Modules. Node-2 is a working base point for the Space Station's robotic arm, Canadarm 2.

Node-2 was developed for NASA under an ESA contract with European industry, with Alcatel-Alenia Space as the prime contractor. Responsibility for Node-2 development was assigned to the Italian space agency, ASI. The structural design is based on that of the Multi-Purpose Logistics Modules and the European Columbus laboratory.

NASA held a competition amongst schoolchildren in the United States to find a name for the Node-2 module. On 15 March 2007 the new name Harmony was announced.

Node-2, or Harmony, was launched in October 2007 on Space Shuttle flight STS-120 (ISS Assembly Flight 10A).
