Poisk (ISS module)

List of ISS modules

Poisk (Russian Поиск for search) earlier Mini - Research Module 2 (Russian Малый исследовательский модуль -2 ( МИМ -2) MIM - 2, Mini Research Module 2) is a module of the International Space Station. It is coupled the previously canceled Russian Docking Compartment 2 ( DC2) and the zenith port of Zvezda in principle. The launch took place as part of a modified Progress- van with a Soyuz rocket. Poisk serves as a coupling module for Soyuz and Progress spacecraft and as an airlock for exits. It is also used for external science experiments, hence the original name. Through the expansion of the station, the use became necessary as a coupling adapter, as since May 2009, are always by the doubling of the ISS crew two Soyuz spacecraft to the ISS. The module is the replacement for Pirs (DC1 ) that is not yet in operation. [ Deprecated]

On October 22, the module got its name. Poisk was launched on 10 November 2009 at 14:22 UTC and has docked on November 12 at 15:41 UTC on Zvezda module. On December 8, 2009 at 00:16 UTC no longer need the service module of Poisk was separated and subsequently checked to crash. For the first time there were four Russian docking port on the ISS available.

Poisk has two docking port: an active saver- type " SSWP -M 8000" at the end of the module is docked to Zvezda, as well as a passive docking port of type " SSWP G4000 " on the opposite end located, may be applied at the spaceships. Poisk acts as a kind of adapters and so in addition to Pirs, Zarya nadir (now Rassvet ) and the rear docking port of the Zvezda module, a fourth possibility for coupling Soyuz spacecraft and Progress cargo ships. Before the coupling of Poisk only three spacecraft could be coupled with Russian coupling adapters at the station.

Poisk based on the Progress- M cargo spacecraft on its drive block or service module, the module itself is attached, which is similar to the Pirs module. Is 4.91 meters long and has a maximum diameter of 2.55 m, an internal volume of 12.5 cubic meters, and weighing about three tons. It brought 750 kg supplies to the ISS and has two inward opening hatches with a diameter of one meter, which are used to seal the airlock. Currently, the module with Strela -1 has its own crane arm to support research and repair measures.
