Summary
MLM Nauka launched on a Khrunichev State Research and Production Space Center Proton-M from 200/39 (200L), Baikonur Cosmodrome, Republic of Kazakhstan on July 21, 2021. It was Khrunichev State Research and Production Space Center's 187th launch, 1st this year and humanity's 6,106th orbital launch attempt. It was the 1st Proton-M flight. The payload was bound for low Earth orbit (LEO). Nauka, one of 4 catalogued objects, reached a 198 × 353 km orbit inclined 51.6°. 4 objects from this launch are catalogued, one of them a payload.

About this launch
Nauka (which means "Science" in Russian), also known as Multipurpose Laboratory Module (MLM), is a new module of the russian segment of the ISS. It will dock at Zvezda's nadir port, replacing the Pirs module occupying it since September 2001. The Nauka module is designed to be used for experiments, docking and cargo as well as serve as a crew work and rest area. It is equipped with full guidance and navigation control including engines and an attitude control system that can be used as a backup by the ISS. The Nauka module also brings the European Robotic Arm, for which a spare elbow joint was already launched in 2010, to the orbital laboratory.
