Poisk (ISS module)

Poisk (Russian: По́иск; 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. Poisk is overall the same design as a docking module Pirs. Whereas Pirs has been attached to the nadir ("bottom") port of Zvezda module, Poisk is attached to the zenith ("top"); Pirs is closer to the Earth with ISS usual orientation and Poisk is on the other side. Poisk is Russian for explore or search. Poisk combines various docking, EVA, and science capabilities. It has two egress hatches for EVA's in addition to the two spacecraft docking ports. Although Poisk is 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 a mini-research module

Poisk docked to the zenith port of the Zvezda module on November 12, 2009, and will serve as a docking port for Soyuz and Progress spacecraft and as an airlock for spacewalks. Poisk will also provide extra space for scientific experiments, and provide power-supply outlets and data-transmission interfaces for two external scientific payloads to be developed by the Russian Academy of Sciences.

Two spacewalks conducted from the ISS in June 2009, successfully completed activities anticipating Poisk module's future berthing.

On 5 June 2009, during Russian Orlan EVA-22 spacewalk Expedition 19/20 Commander Gennady Padalka and Flight Engineer Michael Barratt installed two Kurs docking antennas, a docking target and electrical connectors on the exterior of Zvezda's Service Module.
