ISS Unity Module (Node 1)

The Unity connecting module was the first U.S.-built component of the International Space Station. It is cylindrical in shape, with six berthing locations (forward, aft, port, starboard, zenith, and nadir) facilitating connections to other modules. Sometimes referred to as Node 1, Unity was the first of the three connecting modules; the other two are Harmony and Tranquility.
