Node 1 "Unity" was the first piece of the USOS, launched into space aboard Space Shuttle Endeavour on STS-88. As one of three "Node" modules, it offers one ISPR ring, aswell as six CBM ports. Following the expansion of the ISS, Unity has become the central node, connecting LAB, NOD3, the Airlock and the Russian Segment (RS). Due to its central location the storage locations contain frequently used materials, such as office supplies and tools. The NOD1P1 rack is fitted with a large table and general supplies (N1 Galley).
