Today, on March 19, 2021, in accordance with the Russian Flight Program of the International Space Station, the transport piloted ship “Union MS-17” was successfully rejected from a small research module “Dawn” on the Small Research Module “Search” to free the place for Ship with another expedition to the ISS. Distribution operations, autonomous flight and docking passed in a regular mode using a manual control system.
A few hours before the crew of the transport piloted ship “Union MS-17” as part of the astronauts of Roscosmos Sergey Ryzhikov (commander of the ISS-64), Sergey Kud-Schurchkova (MKS-64 flight engineer), as well as NASA Astronaut Kathlein Rubins (flight engineer The ISS-64) switched to the ship and closed the transitional hatches. After the necessary checks of the seal of the joint and conducting preparatory operations, the crew prepared for the upcoming domain.
At 19:38:31 Moscow time, the Soyuz MS-17 ship separated from the International Space Station and then moved away from it to a distance of about 40 meters. Having done a deployment of the ISS, the ship at 20:12:33 MSK approached to the docking unit of the “Search” module. Operations on the allotment of the ship “Union MS-17”, the departure of it and the subsequent docking was performed by its commander – the cosmonaut of Roskosmos Sergey Ryzhikov using a manual control system. The time of finding the piloted ship in autonomous flight was 34 minutes. After aligning the pressure of the crew in the period from 22:10 – 22:30 MSK will check the tightness of the joint, opens the hatches and return back on board the international space station.
“Restrainment” on the ISS is made to release the dutch assembly in the Dawn Research Module for receiving the piloted ship “Union MS-18”, the launch of which is scheduled for April 9, 2021 from the Baikonur cosmodrome. At the same time, in the composition of the Russian Segment of the ISS, two ships “Union of MS” immediately ensures a direct transmission of the change of prolonged crews of the ISS-64 and ISS-65.
The junction of the ship “Union MS-17” is also due to the need to exit the crew in open space (CCD-48) in order to complete the preparation for the uncoversion and an increase from the Pier’s module for subsequent docking in its place of the laboratory module “Science”. When conducting an ECD-48, it is planned to use the “Search” module as a gateway compartment. The most rationally, in terms of the Action of the ISS crew, and safely, in terms of parrying of possible abnormal situations during reverse gods, the execution of the ECD-48, when the transition compartment of the service module is used as a backup gateway, and the ship on which the crew flew, performing the ECD, is dashed To the “Dawn” module.
At the moment, at the International Space Station, in addition to Sergey Ryzhikov, Sergey Kudu-Schurchkova and Kathleen Rubins, are NASA astronauts Michael Hopkins, Victor Glover, Shannon Walker and Astronaut of the Japanese Agency Aerospace Research Soychi Noguchi. On April 9, the astronauts of Roskosmos Oleg Novitsky, Peter Dubrov and Astronaut NASA Mark Wanda High.
