Prichal nodal module also known as Uzlovoy Module or UM (Russian: Узловой Модуль "Причал", Nodal Module Berth) is a Russian spacecraft which is part of the International Space Station (ISS). It was approved in 2011 and was launched on 24 November 2021, at 13:06:35 UTC, atop Progress M-UM, with operations beginning in 2022.
