Harmony Module
Quick Facts
Harmony has hosted a variety of spacecraft including the SpaceX Dragon crew and cargo spacecraft, both pictured here on June 15, 2023.
Harmony connects three international laboratory modules including Destiny from the U.S., Kibo from Japan, and Columbus from Europe.
Expansion of the International Space Station continued with the delivery of the Harmony node in October 2007. The module acts as an internal connecting port and passageway to international science labs and cargo spacecraft. Harmony is a utility hub, providing air, electrical power, water, and other systems essential to support life on the station. Harmony distributes resources from the station’s truss to the Destiny lab, to the European Space Agency’s Columbus Laboratory, and to the Japanese Kibo Laboratory. In addition to increasing the living and working space inside the station, its exterior also serves as a work platform for the station’s robotic arm, Canadarm2.
