ROSCOSMOS - Russian Vehicles patch.
August 21, 2021
In order to form ballistic conditions, before the launch of the Soyuz MS-19 manned transport vehicle and the landing of the Soyuz MS-18 descent vehicle, another correction of the orbital altitude of the International Space Station was carried out. According to preliminary data, after the maneuver, the average height is now 420.91 km above the Earth's surface.

Today, August 21, 2021, at 07:04 Moscow time, a command was issued and the engines of the Zvezda service module of the ISS Russian segment were turned on. Two correcting motors worked in normal mode for 50 seconds, and the impulse value was 0.71 m / s. According to the updated information of specialists of the ballistic and navigation support service of the Flight Control Center of TsNIIMash (part of the State Corporation Roscosmos), the orbit parameters of the International Space Station were:
- Orbital period - 92.93 minutes;
- Orbital inclination - 51.66 degrees;
- Minimum orbital altitude - 420.56 km;
- The maximum orbital altitude is 437.09 km.
The maneuver was carried out by the engines of the Zvezda service module rather than the Progress MS-17 transport cargo vehicle in order to more efficiently use the fuel, since the space truck is currently docked to the Poisk Small Research Module of the ISS Russian Segment.
The launch of the Soyuz-2.1a carrier rocket with the Soyuz MS-19 manned transport vehicle is scheduled for October 5, 2021 from the Baikonur cosmodrome. The main crew included Roscosmos cosmonaut Anton Shkaplerov, as well as space flight participants - actress Yulia Peresild and director Klim Shipenko. It is expected that on October 17 Peresild and Shipenko will return to Earth on the Soyuz MS-18 spacecraft together with Roscosmos cosmonaut Oleg Novitsky.
