Prichal (Russian: Причал, lit. 'pier'), also known as the Uzlovoy Module (UM, Russian: узловой модуль, romanized: Uzlovoy Modool, lit. 'Node Module') is a Russian-built component of the International Space Station (ISS). This cylindrical module has six docking ports (forward, aft, port, starboard, zenith, and nadir) to provide additional docking ports for Soyuz and Progress spacecraft, as well as potential future modules.
Prichal was launched on 24 November 2021, at 13:06:35 UTC, atop a Soyuz-2.1b rocket and guided automously into the nadir port of the Nauka module by a Progress M-UM spacecraft attached to the Prichal's nadir port. Once in place, the Progress spacecraft disconnected for a destructive reentry. As of 2024, the forward, aft, port and starboard docking ports remain covered.
Prichal was initially intended to be an element of the now canceled Orbital Piloted Assembly and Experiment Complex (OPSEK).
