Description:

• The International Docking Adapter (IDA) is a spacecraft docking system adapter being developed to convert APAS-95 to the NASA Docking System (NDS)/ International Docking System Standard (IDSS). An IDA will be placed on each of the International Space Station's (ISS) two open Pressurized Mating Adapters (PMA), both of which will be located on Node-2 (Harmony module).

Mission details:

• Cargo ship Dragon CRS-18 was launched on Jul 25, 2019.
  Dragon was grappled by the Canadarm-2 at 1311 UTC Jul 27 and berthed on the Harmony nadir port by 1601 UTC Jul 27.
• On Aug 19, 2019 the Dextre arm unberthed the IDA-3 docking adapter from Dragon CRS-18′s trunk. On Aug 21 at about 1100 UTC Dextre soft docked IDA-3 to the PMA-3 docking port. Then, at 1219 UTC, the Quest airlock was depressurised and astronauts Hague and Morgan began spacewalk ISS EVA-55, with spacesuits 3006 and 3008 and SAFER backpack units 18 and 13 respectively. The hatch was open at 1226 UTC and the astronauts went to battery power a minute later. They connected cables to IDA-3 and activated it; IDA-3 was firmlymated to PMA3 between 1443 and 1500 UTC.
  At 1614 UTC Dextre released the IDA and at 1641 UTC the astronauts removed its thermal cover (which was stuffed in a bag and returned to the airlock). Two ‘hemi reflectors′ were installed and after some final connections the astronauts returned to the Quest airlock, with hatch close at 1855 UTC and repressurization at 1859 UTC.
• The PMA-3 port with its APAS adapter was designed for Shuttle dockings; the IDA-3 converts it to be suitable for Crew Dragon and Starliner dockings.
