The Pressurized Mating Adapter (PMA) is a spacecraft adapter that converts the Common Berthing Mechanism (CBM) to APAS-95. There are three PMAs located on the International Space Station (ISS). The first two PMAs were launched with the ''Unity'' module in 1998 aboard STS-88. The third was launched in 2000 aboard STS-92. == Uses == All the PMAs on the ISS are identical〔(Nasa.gov – Elements )〕 but used slightly differently, and all three perform the same basic function of connecting a Common Berthing Mechanism port of an ISS module to an APAS-95 docking port of another module or visiting spacecraft.〔 〕 For this the PMAs carry a passive CBM port and a passive APAS port. They are pressurized and heated from the inside, and through docking rings as well as external connections allow for power and data communications transfer.〔 〕 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「Pressurized Mating Adapter」の詳細全文を読む スポンサード リンク
