International Space Station
Nauka

Nauka (Russian: Наука, lit. ' Science '), also known as the Multipurpose Laboratory Module, Upgrade (Russian: Многоцелевой лабораторный модуль, усоверше́нствованный), is a Roscosmos-funded component of the ISS that was launched on 21 July 2021, 14:58 UTC. In the original ISS plans, Nauka was to use the location of the Docking and Stowage Module (DSM), but the DSM was later replaced by the Rassvet module and moved to Zarya ' s nadir port. Nauka was successfully docked to Zvezda ' s nadir port on 29 July 2021, 13:29 UTC, replacing the Pirs module.

It had a temporary docking adapter on its nadir port for crewed and uncrewed missions until Prichal arrival, where just before its arrival it was removed by a departing Progress spacecraft.
