Common Berthing Mechanism
From Wikipedia, the free encyclopedia
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 provides a 51 inch (130 cm) passage for the crew.
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 docking mechanism for future spacecraft, including the unmanned Japanese H-II Transfer Vehicle (HTV), a resupply vehicle, and the SpaceX Dragon capsule.
