The Common Berthing Mechanism (or CBM) is used to connect all non-Russian pressurized modules of the International Space Station.
The Common Berthing Mechanism consists of two components: the Active Common Berthing Mechanism (ACBM) and the Passive Common Berthing Mechanism (PCBM).[1] Once connected, the two sides of the CBM form a pressure tight seal, which provides automatic transfer of electricity, communications, and fluid. The CBM also features a hatch, which can be opened to reveal a 50 inch (127 cm) diameter passage for crew/cargo transfer. Since this passage is large enough to allow International Standard Payload Racks to be moved through, payloads can be pre-configured in racks and transported to the station aboard the Multi-Purpose Logistics Modules, which use CBM ports.[citation needed]
All ISS Nodes feature 4 radial ACBM ports. Of the 2 axial ports on every Node, only the aft port is a PCBM, with the forward port being an ACBM (apart from the Unity Node, on which both axial ports are ACBM's). All other U.S. segment ISS modules feature only a single PCBM. However, the Destiny Laboratory and the Japanese Pressurised Module (JPM) feature both one PCBM and one ACBM.[citation needed]
The Common Berthing Mechanism was first used to connect the Unity Module and the Z1 truss of the International Space Station.
The CBM is to be used as a berthing mechanism for future spacecraft, including the unmanned Japanese H-II Transfer Vehicle (HTV), a Cygnus resupply vehicle, and the SpaceX Dragon capsule. These spacecraft will feature a PCBM, and will be berthed to the ISS's ACBM using the Space Station's robot arm. However, it will not be used for the new Orion.[citation needed]
