18-593: Using NDS, NASA developed the International Docking Adapter (IDA) to provide two IDSS-compliant docking ports on the ISS. The IDAs were delivered to the ISS starting in 2016. Each of two existing Pressurized Mating Adapters has an IDA permanently attached, so the former PMA function is no longer available for visiting spacecraft. Since 2019, visiting spacecraft that implement IDSS dock to the NDS ports on

36-734: A less complex docking system could be used as the NASA Docking System that both met the international community's desire for a narrower soft capture system ring width, as well as providing the ISS a simpler active docking system compared to the then-planned design. Boeing 's proposal was the Soft Impact Mating and Attenuation Concept (SIMAC), a design originally conceived in 2003 for the Orbital Space Plane (OSP) Program. A leaked NASA internal memo from November 2012, stated that SIMAC had been chosen to replace

54-568: A spacewalk on 19 August 2016. First docking was achieved with the arrival of Crew Dragon Demo-1 on 3 March 2019. IDA-3 was launched on the SpaceX CRS-18 mission in July 2019. IDA-3 is constructed mostly from spare parts to speed construction. It was attached and connected to PMA-3 during a spacewalk on 21 August 2019. First docking was achieved with the arrival of SpaceX CRS-21 on 7 December 2020. Expedition 48 Expedition 48

72-455: A width of 160 cm (63 in). When including the docking targets, laser retro-reflectors and related systems that are arrayed around the outer perimeters, the outer diameter is about 240 cm (94 in). Boeing is the primary contractor for the IDAs and the adapters were assembled at their Houston Product Support Center. Parts from subcontractors came from 25 American states and

90-547: Is constructed mostly from spare parts to speed construction. It was attached and connected to PMA-3 during a spacewalk on 21 August 2019. International Docking Adapter The International Docking Adapter ( IDA ) is a spacecraft docking system adapter developed to convert APAS-95 to support docking with spacecraft that implement the International Docking System Standard . The IDA uses NASA Docking System (NDS) hardware. An IDA

108-628: The Crew Exploration Vehicle (which was later named Orion ) and all applicable future exploration elements. The Hubble Space Telescope received the Soft-Capture Mechanism (SCM) on STS-125 . The SCM is meant for unpressurized docking, but uses the LIDS interface to reserve the possibility of an Orion docked mission. The docking ring is mounted on Hubble's aft bulkhead. It may be used for safely de-orbiting Hubble at

126-572: The Kennedy Space Center while IDA-2 was still at Boeing's Houston facility. The systems and targets for IDA-1 were put through about a month of tests at the Space Station Processing Facility before being loaded for launch. IDA-1 was lost during the launch failure of SpaceX CRS-7 on 28 June 2015. IDA-2 was launched on SpaceX CRS-9 on 18 July 2016. It was attached and connected to PMA-2 during

144-727: The Low Impact Docking System (LIDS). ATLAS was planned to be launched on Orion's first two missions to the International Space Station. Orion's missions to the ISS were later canceled altogether and its role as a crew transporter was replaced by the Commercial Crew Program . The Common Docking Adapter (CDA) was announced in 2009. It was planned to be used to convert the Common Berthing Mechanism to

162-739: The Advanced Docking Berthing System, which would later be called the X-38 Low-Impact Docking System. After the X-38 was canceled in 2002, development of the mating system continued, but its future was unknown. In 2004, President George W. Bush announced his Vision for Space Exploration and NASA's 2005 Exploration Systems Architecture Study was created in response, recommended the use of the Low Impact Docking System (LIDS) for

180-466: The IDAs. These include Crew Dragon , Cargo Dragon 2, and Boeing Starliner . NDS supports both autonomous and piloted dockings and includes pyrotechnics for contingency undocking. Once mated the NDS interface can transfer power, data, and air; future implementations will be able to transfer water, fuel, oxidizer and pressurant as well. The passage for crew and cargo transfer has a diameter of 800 millimetres (31 in). In form and function NDS resembles

198-500: The NASA Docking System. The CDAs would have been attached directly to Node-2 forward and Node-2 zenith. They would have been delivered on the Japanese HTV cargo spacecraft . IDA converts APAS-95 to the NASA Docking System (which complies with the International Docking System Standard ) and allows the transfer of crew, cargo, power and data. IDA has a mass of 526 kg (1,160 lb), a height of 110 cm (42 in) and

216-864: The Shuttle/Soyuz APAS-95 mechanism already in use for the docking ports and pressurized mating adapters on the International Space Station . There is no compatibility with the larger common berthing mechanism used on the US segment of the ISS, the Japanese H-II Transfer Vehicle , the original SpaceX Dragon , and Orbital Sciences' Cygnus spacecraft. NDS is compatible with the IDSS implementation on SpaceX Dragon 2 , both Crew Dragon and Cargo Dragon. In 1996, Johnson Space Center (JSC) began development of

234-469: The electrical connections and permanently connect it to the PMA. IDA-1 was planned to be attached to Node-2's forward PMA. IDA-2 was originally planned to be attached to Node-2's zenith PMA. But following the loss of IDA-1, IDA-2 was instead attached to Node-2's forward PMA (PMA-2). IDA-3, a replacement for IDA-1, is installed at Node-2's zenith PMA (PMA-3). In February 2015, IDA-1 had been transported to

252-400: The end of its service lifetime. In February 2010, the LIDS program became modified to be compliant with the IDSS and became known as the international Low Impact Docking System (iLIDS) or simply the NASA Docking System (NDS). In May 2011, the NDS critical design review was completed and qualification was expected to be completed by late 2013. In April 2012, NASA funded a study to determine if

270-490: The previous design and that the majority of the work on the NASA Docking System would be shifted from NASA JSC to Boeing. In August 2014, Boeing announced that the critical design review for the redesigned NDS had been completed. Following this change the IDSS was modified (to rev D), so the new design of the NASA Docking System is still compatible with the standard. IDA-1 was part of the payload on SpaceX CRS-7 in June 2015, but

288-490: The primary structure is from Russian company RSC Energia . Each IDA was delivered as unpressurized cargo in the trunk of a SpaceX Dragon 1 . When each IDA arrived, Dextre removed it from Dragon's trunk and moved it to about 30 cm (1 ft) from the front of the PMA. It then moved the IDA carefully into position until it was seated on the PMA and held it there. Astronauts during an Extravehicular activity then completed

306-544: Was destroyed when the Falcon 9 rocket exploded during ascent. IDA-2 was delivered successfully on SpaceX's CRS-9 mission in July 2016, and then installed on PMA-2 in August of that year during a spacewalk by Jeffrey Williams and Kathleen Rubins as part of Expedition 48 . Crew Dragon Demo-1 was the first spacecraft to dock at this port on 2 March 2019. IDA-3 was launched on the SpaceX CRS-18 mission in July 2019. IDA-3

324-482: Was permanently installed on each of the International Space Station 's (ISS) two open Pressurized Mating Adapters (PMAs), both of which are connected to the Harmony module . Prior to IDA several different docking adapters were designed to fill a similar role but were never implemented. The APAS to LIDS Adaptor System (ATLAS) was announced in 2008. It would have been placed on the open PMAs and converted APAS-95 to
