ISS Harmony Module (Node 2)

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. The successful installation of Harmony meant that from NASA’s perspective, the station was “U.S. Core Complete”.

 

The Harmony (Node 2) module placed between JEM and Columbus module.
