The two correcting motors ran for 38.9 seconds, and the impulse value was 0.54 m / s. According to the specialists of the ballistic and navigation support service of the Flight Control Center of TsNIIMash (part of the Roscosmos State Corporation), the parameters of the ISS orbit are:

- Orbital period: 92.92 min;
- Orbital inclination: 51.66 degrees;
- Minimum orbital altitude: 419.44 km;
- Maximum orbital altitude: 441.21 km.

Previously, the orbital altitude of the ISS was corrected on September 24, 2021.

The launch of the Soyuz MS-20 manned transport vehicle with two "space tourists" is scheduled for December 8, 2021. The flight duration will be 12 days. The Soyuz MS-20 will be controlled by Roscosmos cosmonaut Alexander Misurkin, and Japanese billionaire entrepreneur Yusaku Maezawa and his assistant Yozo Hirano will also be on board.

Currently, ten crew members are working on board the International Space Station: Roscosmos cosmonauts Oleg Novitsky, Pyotr Dubrov and Anton Shkaplerov, space flight participants under the Challenge scientific and educational project Yulia Peresild and Klim Shipenko, NASA astronauts Mark Wande Hei, Shane Kimbrough and Megan MacArthur, ESA astronaut Thomas Pesquet, and JAXA astronaut Akihiko Hoshide.
