The Common Berthing Mechanism (CBM) for International Space Station

The International Space Station (ISS) Program utilizes the Common Berthing Mechanism (CBM) hardware to mate/berth or demate/deberth two pressurized elements on-orbit. Berthing and deberthing of two elements together on-orbit occurs many times throughout the Space Station Assembly Sequence to provide pressurized access between the module vestibules via hatches. The CBM system was developed by Boeing at Marshall Space Flight Center (MSFC) in Huntsville, Alabama, under contract to NASA, and the CBM Control and Actuation Components were developed by Honeywell Engines & Systems in Torrance, California, under contract to Boeing.
