Poisk, which was launched to the station on a modified Progress spacecraft, is almost identical to the Pirs Docking Compartment. It provides the capability for extravehicular activity using Russian Orlan spacesuits. Poisk also provides systems for servicing and refurbishing the spacesuits themselves. The zenith docking system on Poisk provides a port for the docking of both Soyuz and Progress vehicles.

Poisk provides extra space for science experiments, including power supply outlets and data transmission interfaces for five external workstations. The module also is equipped with three temporary workstations near the module’s side windows to observe local horizon plane and to accommodate payloads equipped with vacuum interfaces.
