In accordance with the flight program of the International Space Station (ISS), on January 18, 2019, a planned correction of the ISS orbit was performed.
To conduct a maneuver at 21 hours 01 min. (Moscow time), the engines system of the “Progress MS-10” transport cargo ship, docked to the ISS, was switched on.
The engines system working time was 500 seconds.
As a result, the station received a speed increment of 1 m / s.
According to the data of the ballistic-navigation support service of the Mission Control Center, the calculated parameters of the ISS orbit after the execution of the maneuver were:
– the minimum height above the Earth’s surface is 407.4 km,
– the maximum height above the Earth’s surface is 422.2 km,
– period of circulation – 92.62 minutes,
– inclination of the orbit – 51.66 degrees.
The purpose of the correction was the formation of ballistic conditions for the flight of Russian transport ships.
