The International Docking System Standard (IDSS) Interface Definition Document (IDD) establishes a standard docking interface to enable collaborative endeavors between the International space fairing community while also supporting possible crew rescue operations. The IDSS was developed by the ISS participating partners and first baselined in 2010, with the goal to support the following missions:
- International Space Station (ISS) visitation and other Low Earth Orbit (LEO) platforms.
- Exploration missions beyond LEO.
- Crew rescue.
- International cooperative mission.
