ROSCOSMOS - Russian Vehicles patch.
Dec 24, 2021
The orbital altitude of the International Space Station was adjusted in order to form the initial ballistic conditions before the launch of the Soyuz MS-21 manned spacecraft into orbit and the landing of the Soyuz MS-19 descent vehicle in 2022. According to preliminary data, after the maneuver, the ISS orbital altitude decreased by 1.89 km.
International Space Station (ISS)
On Friday, December 24, 2021, at 04:18 Moscow time, a command was issued and the engines of the Progress MS-18 cargo vehicle docked to the Russian segment of the ISS were turned on. They worked for 544 seconds, and the impulse value was 1.02 m / s. According to the updated data from the ballistic and navigation support service of the Flight Control Center of TsNIIMash, the parameters of the ISS orbit after the evasion maneuver were:
- Circulation period: 92.86 minutes;
- Orbital inclination: 51.66 degrees;
- Minimum orbital altitude: 415.63 km;
- Maximum orbital altitude: 433.15 km.
Earlier, the station's orbital altitude was adjusted on December 3 in order to evade "space debris" - a stage fragment of the American Pegasus launch vehicle launched from the US in 1994.
The launch of the Soyuz MS-21 manned transport vehicle with the crew of the 67th long-term expedition is scheduled for March 18, 2022. For the first time, the transport vehicle should dock to the Prichal nodal module, which in November 2021 became part of the Russian segment of the ISS. The landing of the Soyuz MS-19 descent vehicle with Roscosmos cosmonauts Anton Shkaplerov and Peter Dubrov, as well as NASA astronaut Mark Vande Hei, is scheduled for late March.
