ROSCOSMOS - Russian Vehicles patch.
April 1, 2021
In accordance with the flight program of the International Space Station, on April 2, 2021, specialists from the TsNIIMash Mission Control Center (part of the Roscosmos State Corporation) will correct the altitude of its orbit. For this, the engines of the Progress MS-14 transport cargo vehicle docked to the Zvezda service module will be automatically switched on at 15:14 Moscow time.

The impulse value will be 0.21 m/s. The spacecraft's engines will operate for 129.3 seconds, as a result of which the average altitude of the station's orbit will increase by 0.36 km and will amount to 419.8 km. According to preliminary information from the ballistic and navigation support service of MCC TsNIIMash, the parameters of the ISS orbit will be:
- 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: 439.79 km.
This maneuver is performed to form ballistic conditions before the launch of the Soyuz MS-18 manned spacecraft and the Soyuz MS-17 landing, which are scheduled for April 2021. On April 9, Roscosmos cosmonauts Oleg Novitsky, Pyotr Dubrov, as well as NASA astronaut Mark Vande Hai will go to the ISS.
