International Space Station scheduled orbit correction conducted

Roscosmos specialists conducted an orbit correction of the International Space Station using the Progress MS-14 cargo spacecraft engines on October 7, 2020. The engines of the spacecraft docked to Zvezda module were automatically switched on at 08:26 UTC for 412.9 seconds decreasing the station mean orbit altitude by 1.3 km to about 418.6 km.

The orbit correction went in accordance with the calculated data. According to TsNIIMash Mission Control Center (part of Roscosmos) data, the station orbit parameters after the correction are as follows:

  • Rotation period — 92.88 min;

  • Orbit inclination — 51.66 deg.

  • Minimal altitude over the Earth’s surface — 417.96 km;

  • Maximum altitude over the Earth’s surface — 436.55 km;

The adjustment was conducted to form ballistic conditions prior to the Soyuz MS-17 crewed spacecraft launch and docking scheduled for October 14, 2020. The ISS-64 long-term expedition prime crew includes Roscosmos cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov, as well as NASA astronaut Kathleen Rubins. Their backups are Roscosmos cosmonauts Oleg Novitsky, Pyotr Dubrov, and NASA astronaut Mark Vande Hei. Currently, both crews are taking preflight preparations at the Baikonur Cosmodrome.
