Italian-built NASA module delivered in October 2007 to the International Space Station (ISS) aboard the space shuttle Discovery. Formerly known as Node 2, Harmony is 7.19 metres long, 4.42 metres wide, and weighs 14 288 kilograms at launch. The pressurized module acts as an internal connecting port and passageway to international science labs and cargo spacecraft, distributing resources from the station’s truss to the Destiny lab, to the European Space Agency’s Columbus laboratory, and to the Japanese Kibo laboratory. Installation of the module completed the US Core of the station. On 15 March 2007 the new name Harmony was announced, after the ninth-grade class at Lubbock High School in Lubbock, Texas, won a national competition to name it. Harmony is the first US piece of the ISS named by someone outside of NASA.
