ROSCOSMOS - Russian Vehicles patch.
April 3, 2021
In accordance with the flight program of the International Space Station, on April 2, 2021, specialists from the Mission Control Center of TsNIIMash (part of the Roscosmos State Corporation) corrected the altitude of its orbit. For this, the engines of the Progress MS-14 transport cargo vehicle docked to the Zvezda service module of the ISS Russian segment were automatically switched on at 15:14 Moscow time. The impulse value was 0.21 m/s.

The engines of the "space truck" worked for 132.8 seconds in order to increase the average altitude of the station's orbit by 0.36 km and amounted to 419.85 km. At present, specialists from the ballistic and navigation support service of the TsNIIMash MCC are analyzing the received telemetry information and refining the parameters of the ISS orbit.

According to the ballistic and navigation support service of the TsNIIMash MCC, the parameters of the ISS orbit were:
- Orbital period: 92.91 min;
- Orbital inclination: 51.66 degrees;
- Minimum height above the Earth's surface: 418.17 km;
- Maximum height above the surface of the Earth: 439.77 km.
This maneuver was performed to form ballistic conditions before the landing of the Soyuz MS-17 spacecraft and before the launch of the Soyuz MS-18 spacecraft, which is scheduled for April 9, 2021. Roscosmos cosmonauts Oleg Novitsky, Pyotr Dubrov, as well as NASA astronaut Mark Vande Hai will go on it. Currently, the crew of the 64th long-term expedition, consisting of Roscosmos cosmonauts Sergei Ryzhikov and Sergei Kud-Sverchkov, as well as NASA astronauts Kathleen Rubins, Michael Hopkins, Victor Glover, Shannon Walker, and JAXA astronaut Soichi Noguchi, are working on board the International Space Station.
