Unity, also known as Node 1, was the first American-built component of the International Space Station. Boeing built the aluminium module for NASA, and it links the Russian Orbital Segment to the US Orbital Segment. Space Shuttle Endeavour launched it on STS-88 on 4 December 1998, and two days later it was berthed to the already-launched Zarya module. That was the first connection between pieces of the station. It has six Common Berthing Mechanism locations: forward, aft, port, starboard, zenith and nadir, and it is 4.57 metres in diameter. Destiny and the Quest Joint Airlock attach to it.
