Roscosmos. Nauka is in orbit!

July 21, 2021

July 21, 2021, at 17:58:25 Moscow Time, launch vehicle Proton-M carrying the multi-purpose laboratory module Nauka lifted off launch pad No.39 of Site No.200 of the Baikonur Cosmodrome. According to telemetry data, all the launch vehicle flight events (staging and payload fairing jettison) went normally.

The launch vehicle Proton-M put the multi-purpose laboratory module Nauka into a low Earth orbit with the following parameters:

  • Apogee altitude 350.1 km,
  • Perigee altitude 190.0 km,
  • orbital inclination 51.6 degrees.

In the accordance with the timeline, 580.3 seconds into the flight the ascent unit separated from the third stage of the launch vehicle. Further maneuvers for the rendezvous with the International Space Station are carried out using thrusters on the Nauka module. The duration of the module transit to the ISS docking area is 8 days. The docking with the Zvezda module is scheduled for July 29, 2021 at 16:26:00 Moscow Time.

The launch vehicle Proton-M is serially manufactured at Khrunichev Center (which is a part of State Corporation Roscosmos ) is used for insertion of payloads into specified orbits and departure trajectories under Federal and commercial programs since 2001. Over the years of its operation, Proton-M has undergone four phases of radical upgrades, which significantly improved its mass, performance and environmental characteristics during launches of heavy single and dual payloads. Todays launch was the 425th launch for the entire Proton family, and the 111th launch for the upgraded version.

Nauka is the multi-purpose laboratory module of the Russian Segment of the International Space Station, It was developed by a network of contactors in order to implement a program of scientific experiments and expand the functionality of the ISS Russian Segment. After it is placed into operation, the Russian Segment will have additional volumes for workstations and cargo stowage, for water and oxygen regeneration hardware.

The module is designed to:

  • provide support for docking with logistics spacecraft Progress MS, crew transportation spacecraft Soyuz MS and Node Module Prichal;
  • provide roll control for the International Space Station,
  • support reception of propellant from Progress-MS logistics spacecraft, its storage and transfer to the tanks of the Zvezda module for performing dynamic operations orbital reboost, ISS attitude control and stabilization;
  • store cargoes delivered in the interests of the ISS Russian Segment;
  • provide support to operations of the European robotic arm ERA;
  • support functioning of a suite of utilization payloads for carrying out a program of scientific and applied research, while providing a more comfortable environment for the crew;
  • produce oxygen to support a crew of up to 6;
  • operate an airlock to support utilization payload activities, including those involving the use of the European Robotic Arm;
  • provide an onboard workshop and the crew quarters for a third crewmember of the ISS Russian Segment, as well as support for operation of a space toilet with a system for recycling water from urine.
