Summary
The ISS (NAUKA), also known as Nauka, is a space station module based on the Almaz Bus and 77K (TKS) configuration, launched by Russia on July 21, 2021, from LC200/39 at TYSMC using a Proton-M launch vehicle. This module measures 13.2 meters in length, has a diameter of 4.2 meters, and spans 23.9 meters when its solar arrays are deployed. The dry mass is 19,200 kg with an initial launch mass of 19,627 kg. It was manufactured by KHRO/RKKE for the Russian space agency (RKKE) to serve as a space station module and carries the payload designated 77KML No. 17901. The power system consists of two deployable solar arrays and batteries to support its operational needs. With an expected lifetime of 15 years, Nauka contributes to the International Space Station's research capabilities.
