Poisk (ISS Module)

Poisk, Russian for search or explore and also known as Mini-Research Module 2 or MRM 2, is a Russian docking module of the International Space Station. It was launched on 10 November 2009 attached to a modified Progress spacecraft, Progress M-MIM2, on a Soyuz-U rocket from Baikonur, and docked to the zenith port of the Zvezda module on 12 November 2009, the first major Russian addition to the station since 2001. It follows the design of the Pirs docking compartment, with two docking ports for Soyuz and Progress spacecraft and two egress hatches for spacewalks, and it also provides extra space for experiments, power outlets and data interfaces for two external scientific payloads. It was designed and manufactured by S.P. Korolev RSC Energia. Since a spacewalk in November 2020 it has been used for Russian spacewalks in place of the decommissioned Pirs.
