MOSCOW (Roscosmos PR) — On Tuesday, July 27, 2021, specialists of the flight control group of the multipurpose module “Nauka” at the Mission Control Center of TsNIIMash (part of the State Corporation “Roscosmos”) routinely carried out a corrective maneuver of the module launched last Wednesday to the International Space Station.
The next firing for further orbit alignment is scheduled for July 28th.
The day before, the Progress MS-16 cargo vehicle with the Pirs module of the ISS Russian segment undocked from the Zvezda module of the International Space Station. Last night, Flight Control Center specialists examined the docking station of the nadir port of the service module, where it is planned to dock the multipurpose laboratory module. As a result of the analysis, the absence of mechanical interference for the docking was stated. Thus, the readiness of the docking assemblies for the planned docking of Nauka has been confirmed, and an unscheduled spacewalk is not required.
Thanks to the cosmonauts of Roskosmos Oleg Novitsky and Peter Dubrov, we can see the undocking of the Pirs module from the International Space Station in 4K quality.
MOSCOW (Roscosmos PR) — In accordance with the flight program of the Russian segment of the International Space Station, today, on July 26, 2021, the Progress MS-16 transport cargo vehicle with the Pirs docking module undocked from the ISS.
Editor’s Note: The undocking of the Pirs module from the International Space Station had been scheduled for Friday to make way for the new Nauka science module. The delaty is due to problems with Nauka’s engines and docking system after launch from Baikonur Cosmodrome last week. Those issues have apparently been resolved.
MOSCOW (Roscosmos PR) — Based on the results of an operational meeting of the control group at the Flight Control Center of TsNIIMash (part of the Roscosmos State Corporation), specialists, based on the data obtained from telemetry and based on the need to build optimal orbit conditions, decided to adjust the plans for undocking the Pirs module. These operations are currently scheduled for Monday 26 July 2021.
On Saturday, Roscosmos cosmonauts Oleg Novitsky and Pyotr Dubrov closed the transfer hatches between the Pirs module and the Russian segment of the International Space Station, and checked them for leaks. The physical separation of the bundle from the Progress MS-16 cargo vehicle and the Pirs module from the ISS is tentatively scheduled at 13:56 Moscow time on July 26, and the fall of the fireproof structural elements of the module and the ship in the Pacific Ocean – at 17:51 Moscow time. the same day.
Now the Pirs docking module is docked to the nadir port of the Zvezda service module of the Russian segment of the station. It is planned that after undocking its place will be taken by the multipurpose laboratory module “Science”, which was launched on Wednesday from the Baikonur cosmodrome and is in autonomous flight.
On the eve of this event, the Aist-2D small Earth remote sensing spacecraft, developed at the Progress Rocket and Space Center (Samara, part of the Roscosmos State Corporation), photographed the International Space Station. RCC “Progress” is the operator of the satellite “Aist-2D”, providing control, reception, processing and distribution of the received information of remote sensing of the Earth.
HOUSTON (NASA PR) — NASA will provide live coverage of a new Russian science module’s launch and automated docking to the International Space Station, and the undocking of another module that has been part of the orbital outpost for the past 20 years. Live coverage of all events will be available on NASA Television, the NASA app, and the agency’s website.
MOSCOW (Roscosmos PR) — The Russian crewmembers of the 65th long-term expedition to the International Space Station are preparing the Pirs module for undocking from the Russian segment of the ISS. Given that the Proton-M carrier rocket launches with the Nauka module on July 21, 2021, Pirs undocking is scheduled for July 23.
MOSCOW (Roscosmos PR) — In accordance with the State Commission decision, the Proton-M carrier rocket with the new Nauka laboratory module is scheduled to launch from Site 200 of the Baikonur Cosmodrome on July 21, 2021 at 14:58:21 UTC. Reserve dates: July 22 and 23. Its flight to the International Space Station will take 8 days, and docking to the nadir port of the Zvezda service module is scheduled for July 29, expected at 13:26 UTC.
MOSCOW (Roscosmos PR) — The exit hatch of the Small Research Module “Poisk” is closed, cosmonauts of the Roscosmos detachment Oleg Novitsky and Peter Dubrov completed the 48th planned spacewalk (EVK-48). On their debut, they successfully completed all the equipment installation work on the outer surface of the Russian segment of the International Space Station. The hatch of the Poisk docking bay was closed at 16:12 Moscow time on June 2, 2021. The duration of the extravehicular activity was 7 hours 19 minutes.
HOUSTON (NASA PR) — An uncrewed Russian Progress 77 spacecraft arrived at the International Space Station’s Pirs docking compartment on the station’s Russian segment at 1:27 a.m. EST, two days after lifting off from the Baikonur Cosmodrome in Kazakhstan Sunday, Feb. 14 at 11:45 p.m. EST (9:45 a.m. Monday, Feb. 15, Baikonur time). The spacecraft were flying over Argentina at the time of docking.
