A component of the International Space Station (ISS) that attaches to one end of the US Destiny laboratory module. It acts as a connecting hub to three other science experiment facilities: the Kibo Japanese Experiment Module, the European Columbus Laboratory, and the Centrifuge Accommodation Module. It also provides attachment ports for Multi-Purpose Logistics Modules (MPLMs), the Japanese H II Transfer Vehicle, and the Pressurized Mating Adapter to which space shuttles dock. Node 2 is an aluminium cylinder 6.7 m long and 4.5 m in diameter. It was built in Europe in exchange for the launch of the European Columbus Laboratory to the ISS. Node 1, known as Unity, was launched in December 1998 and is attached to the opposite end of the Destiny module. The arrival of Node 2 will complete the assembly of the US-owned parts of the ISS.
