NASA Docking System
The NASA Docking System is NASA's implementation of the
Using NDS, NASA developed the
Design
The NDS docking mechanism is androgynous, the first system to use low impact technology and the first system to allow both docking and berthing.[2][citation needed] It supports both autonomous and piloted dockings and features pyrotechnics for contingency undocking. Once mated the NDS interface can transfer power, data, and air; in future implementations it will be able to transfer water, fuel, oxidizer and pressurant as well.[1] The passage for crew and cargo transfer has a diameter of 800 millimetres (31 in).[3]
In form and function NDS resembles the Shuttle/Soyuz
History
In 1996,
The Hubble Space Telescope received the Soft-Capture Mechanism (SCM) on STS-125.[8] The SCM is meant for unpressurized docking, but uses the LIDS interface to reserve the possibility of an Orion docked mission.[8] The docking ring is mounted on Hubble's aft bulkhead.[8] It may be used for safely de-orbiting Hubble at the end of its service lifetime.[8]
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).[2] In May 2011, the NDS critical design review was completed and qualification was expected to be completed by late 2013.[9]
In April 2012, NASA funded a study to determine if 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.
A leaked NASA internal memo from November 2012, stated that SIMAC had been chosen to replace the previous design and that the majority of the work on the NASA Docking System would be shifted from NASA JSC to Boeing.[11] In August 2014, Boeing announced that the critical design review for the redesigned NDS had been completed.[12] 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.[10][3][12]
IDA-1 was part of the payload on SpaceX CRS-7 in June 2015, but was destroyed when the Falcon 9 rocket exploded during ascent.[13]
IDA-2 was delivered successfully on SpaceX's
IDA-3 was launched on the SpaceX CRS-18 mission in July 2019.[15] IDA-3 is constructed mostly from spare parts to speed construction.[16] It was attached and connected to PMA-3 during a spacewalk on 21 August 2019. [17]
