The NASA Docking System (NDS) is a spacecraft docking and berthing mechanism being developed for future US human spaceflight vehicles, such as the Orion Multi-Purpose Crew Vehicle and the Commercial Crew vehicles. The NDS is NASA’s implementation of the International Docking System Standard (IDSS), an attempt by the International Space Station Multilateral Coordination Board (MCB) to create an international spacecraft docking standard. NDS is also known as the international Low Impact Docking System (iLIDS).〔 Two International Docking Adapters (IDA) will be attached to the ISS' Pressurized Mating Adapters (PMA), one at Node-2 forward, the other at Node-2 zenith.〔 These will convert the Androgynous Peripheral Attach System-95 (APAS-95) to the NASA Docking System.〔 The IDAs were scheduled to be delivered to ISS by the Dragon spacecraft on separate Commercial Resupply Services missions in 2015.〔(【引用サイトリンク】title=Dragon C2, CRS-1,... CRS-12 )〕 IDA-1 was lost when CRS-7 was destroyed during launch in June 2015. ==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.〔(NASA Docking System (NDS) Technical Integration Meeting (2010-11-17) )〕 It supports both autonomous and piloted dockings and features pyrotechnics for contingency undocking. Once mated the NDS interface can transfer power, data, commands, air, communication and in 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 .〔 〕 In form and function NDS bears some resemblance to the APAS-95 mechanism already in use on the PMAs attached to the International Space Station, but is not completely compatible with it. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NASA Docking System」の詳細全文を読む スポンサード リンク
