The NASA Docking System is NASA's implementation of the International Docking System Standard (IDSS), an international spacecraft docking standard promulgated by the International Space Station Multilateral Coordination Board. NDS is a spacecraft docking and berthing mechanism used on the International Space Station (ISS) and the Boeing Starliner and planned to be used on the Orion spacecraft. The international Low Impact Docking System (iLIDS) was the precursor to the NDS. NDS Block 1 was designed, built, and tested by The Boeing Company in Huntsville, AL. Design qualification testing took place through January 2017.

Docking and berthing of spacecraft
Docking and berthing of spacecraft is the joining of two space vehicles. This connection can be temporary, or partially permanent such as for space station modules.

The first spacecraft docking was performed between Gemini 8 and an uncrewed Agena Target Vehicle on March 16, 1966.
