Harmony Module

The Harmony module, also known as Node 2, is a vital connecting hub aboard the International Space Station that links several key laboratories and living areas together. It provides passageways to modules used by the United States, Europe, and Japan, making it an important center for both daily operations and international cooperation in orbit. Beyond its structural role, Harmony supports crew living quarters, power distribution, and data systems, helping create a functional and connected environment where astronauts can live, work, and conduct research as part of a shared global mission in space.
