International Space Station orbit increased by 1.1 km

On November 12, 2020, TsNIIMash Mission Control Center specialists (part of Roscosmos) conducted an orbit correction of the International Space Station in accordance with its flight program.

To do so, the Progress MS-14 cargo spacecraft engines docked to Zvezda module were automatically switched on at 19:50 UTC.

The orbit correction went in full accordance with the calculated data. The cargo vehicle engines were switched on for 363.5 seconds increasing the station mean orbit altitude by 1.1 km to about 419.35 km. According to TsNIIMash Mission Control Center 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 — 418.42 km;

  • Maximum altitude over the Earth’s surface — 437.95 km;

The adjustment was conducted to initially form ballistic conditions prior to the Soyuz MS-18 crewed spacecraft launch and docking scheduled for April 2021.

The previous orbit correction was conducted on October 7, 2020 with Progress MS-14 working for 412.9 seconds and the station mean orbit altitude decreasing by 1.3 km to about 418.6 km.

Progress MS-14 cargo spacecraft has been in low-Earth orbit since April 25, 2020. During its lifetime, the vehicle has conducted seven ISS orbit corrections including an off-schedule one to evade space debris.
