ROSCOSMOS - Russian Vehicles patch.
Sept. 23, 2020
In connection with the unscheduled correction of the orbit of the International Space Station to avoid "space debris" held on September 23, 2020, the Mission Control Center (Korolev, Moscow Region) made a decision to form ballistic conditions before the launch of the Soyuz MS-17 manned spacecraft on changing the parameters of the planned ISS orbit correction on October 7, 2020.
According to preliminary data from the ballistic and navigation support service of the Flight Control Center of the Central Research Institute of Mechanical Engineering (part of the Roscosmos State Corporation), the engines of the Progress MS-14 cargo ship docked to the aggregate compartment of the Zvezda module will be turned on at 11:11 Moscow time and will work 403.7 s. After carrying out the corrective maneuver, the average altitude of the station's orbit will decrease by 1.4 km and will be about 418.4 km above the Earth's surface.
The launch of the Soyuz-2.1a carrier rocket with the Soyuz MS-17 manned spacecraft and the crew of the 64th long-term expedition to the International Space Station is scheduled for October 14, 2020 from the Baikonur cosmodrome. The prime crew includes Roscosmos cosmonauts Sergei Ryzhikov and Sergei Kud-Sverchkov, as well as NASA astronaut Kathleen Rubins. Back-up crew: Roscosmos cosmonauts Oleg Novitsky, Peter Dubrov and NASA astronaut Mark Vande Hai.

An unscheduled correction of the ISS orbit was carried out
On the evening of September 22, 2020, the Russian Mission Control Center received information that the International Space Station is part of the so-called. The "red zone". This means that there is a danger of collision between the station and "space debris".
After analyzing the available information, the flight control group of the International Space Station made a decision on the need for an urgent evasion maneuver.
The engines of the Progress MS-14 cargo vehicle were switched on at 00:19 Moscow time on September 23 and worked for 150 seconds, giving the station an impulse of 0.3 m/s, as a result of which it evaded a dangerous object.
