ISS scheduled orbit correction conducted

On September 10, 2020, an orbit correction of the International Space Station was conducted using the Progress MS-14 cargo spacecraft engines.

The engines were switched on at 20:32 UTC for 225 seconds giving the station velocity increment of 0.45 meters per second. As a result, the ISS mean orbit altitude increased by 0.8 km.

According to TsNIIMash Mission Control Center (part of Roscosmos) data, the station orbit parameters after the correction are as follows:

  • Rotation period — 92.90 min;

  • Orbit inclination — 51.66 deg.

  • Minimal altitude over the Earth’s surface — 419.6 km;

  • Maximum altitude over the Earth’s surface — 437.9 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 spacecraft 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.
