International Effort Brings an Open Standard For Docking In Space

Posted by timothy on from the best-place-to-dock dept.

FTL writes "Engineers from the US, Russia, Japan, Canada and Europe have come together to publish an International Docking Standard for spaceships. Currently the space station has three different types of incompatible docking ports, and the Chinese are developing their own. Standardizing on one type would permit interoperability and facilitate emergency rescues."

    "Currently the space station has three different types of incompatible docking ports"

    No, it has two. APAS , which is used by Shuttle, and Probe and Cone used by Soyuz, Progress, and ATV.
     
    The third system (CBM) is used by MPLM and HTV, and cannot be docked to. The difference is important - as the docking mechanism can take the full force of an approaching spacecraft, and berthing mechanisms cannot. To berth, one has to station keep with the station, and then be picked up and attached by the station's CANADARM-2 manipulator arm.

    The other important difference is size, APAS and Probe and Cone are limited to essentially man sized tunnels. CBM is a full sized door.

    The International Docking Standard actually already exists aboard the station - as APAS.
