Crossword clues for pirs

Pirs (ISS module)

Pirs (, meaning " pier") -- also called "Stykovochny Otsek 1" or "SO-1" (, " docking module", or DC-1 (docking compartment) -- is one of the two Russian docking compartments originally planned for the ISS. Pirs was launched in August 2001. It provides the ISS with one docking port for Soyuz and Progress spacecraft, and allows egress and ingress for spacewalks by cosmonauts using Russian Orlan space suits.

A second docking compartment, "Stykovochniy Otsek 2" or SO-2, was initially planned with the same design. However, when the Russian segment of the ISS was redesigned in 2001, the new design no longer included the SO-2, and its construction was canceled. After another change of plans the SO-2 module finally evolved into the Poisk module, which was added to the ISS in 2009.

Pirs is scheduled to be detached from the ISS in 2017 and to be deorbited, to make room for the Russian Multipurpose Laboratory Module Nauka.
