MOSCOW (Roscosmos PR) — In accordance with the International Space Station flight program, today, July 29, 2021, at 16:29:06 Moscow time, the Nauka multipurpose laboratory module docked with the nadir docking port of the Zvezda service module of the ISS Russian segment. According to telemetry data and reports from the ISS crew, the on-board systems of the station and the “Nauka” module are functioning normally.

The multipurpose module “Nauka” was successfully launched into low-earth orbit on July 21, 2021 using a heavy launch vehicle “Proton-M”. After separating from the third stage, he was accepted for escort by the ground services of the TsNIIMash Mission Control Center near Moscow (part of the Roscosmos State Corporation), completed the construction of the required orientation, deployed solar panels and radio antennas, and then began an eight-day rendezvous program with the station.

At the autonomous rendezvous section, specialists from the Main Operational Control Group (LOCT, RSC Energia named after SP Korolev, part of Roscosmos) performed several firing of the module’s engines to raise and correct the orbit, as well as to enter the meeting area with the ISS at estimated time. The operations of flying around the station, hovering, docking and docking with the Zvezda service module were carried out under the supervision of LOCT specialists and Russian crew members of the long-term expedition ISS-65, Roscosmos cosmonauts Oleg Novitsky and Peter Dubrov. This docking was the first since 2010, when the small research module No. 1 “Rassvet” was docked to the station.

Within 1.5 hours after the completion of the docking, the cosmonauts will check the tightness of the docking connections and technological communications. At 18:15 Moscow time, it is planned to open the hatch of the transition compartment of the Zvezda module and in a few minutes more – the hatch of the new Russian module, as well as the entry of the crew into the living area of ​​the instrument-sealed compartment. The program of today’s work is limited to the installation of instruments for the analysis and purification of the atmosphere on board the arrived “Science”.
