It is noted that "according to preliminary data, after the corrective maneuver, the station's orbit height should increase by 750 m."

“On Saturday, September 11, 2021, at 21:54 Moscow time, a command was issued and the engines of the Zvezda service module of the ISS Russian segment were turned on. The two correcting motors in the normal mode worked for 31 seconds, and the impulse value was 0.45 m / s. At present, specialists of the ballistic and navigation support service of the TsNIIMash Flight Control Center (part of the Roscosmos State Corporation) are studying the received telemetric information, the results of which will be used to announce the exact parameters of the orbit of the International Space Station, ”the message says.

The company explained that “this maneuver was carried out by the engines of the Zvezda service module, and not the Progress MS-17 transport cargo vehicle, in order to use more fuel efficiently, since the space truck was docked to the Poisk Small Research Module.
