Poisk (ISS module)
Docking compartment of the International Space Station / From Wikipedia, the free encyclopedia
Poisk (Russian: Поиск, lit. 'Search'), also known as the Mini-Research Module 2 (MRM 2), Малый исследовательский модуль 2, or МИМ 2, is a docking module of the International Space Station. Its original name was Docking Module 2 (Stykovochniy Otsek 2, SO-2), as it is almost identical to the Pirs Docking Compartment. Added in 2009, Poisk was the first major Russian addition to the International Space Station since 2001.[1] Poisk is overall the same design as the docking module Pirs.[2] Whereas Pirs was attached to the nadir ("bottom") port of Zvezda, Poisk is attached to the zenith ("top"); Pirs was closer to the Earth with the ISS in its usual orientation, and Poisk is on the other side. Poisk is Russian for explore or search.[3][4] Poisk combines various docking, EVA, and science capabilities.[5] It has two egress hatches for EVAs in addition to the two spacecraft docking ports.[6] Although Poisk is designated as Mini-Research Module 2, it arrived before Mini-Research Module 1 (Rassvet), which had a different design; Poisk looks more like the Pirs docking port, which is not designated as a mini-research module.
