Pirs (ISS module)
Pirs (Russian: Пирс, meaning "pier") – also called Stykovochny Otsek 1 (SO-1; Russian: Стыковочный отсек, "docking module") and DC-1 (Docking Compartment 1) – was a Russian module on the International Space Station (ISS). Pirs was launched on 14 September 2001, and was located on the Zvezda module of the station. It provided the ISS with one docking port for Soyuz and Progress spacecraft, and allowed egress and ingress for spacewalks by cosmonauts using Russian Orlan space suits. Pirs was docked to Zvezda for almost 20 years, until 26 July 2021, where it was decommissioned and undocked by Progress MS-16 to make way for the new Nauka module.
