The Nauka module docked to the ISS on July 29 and Roskosmos broadcast the docking in real time. At the time mark 16.27 below the module going to the docking, a luminous object appeared, which, having caught up with the ISS (being below it), sharply increased the flight speed (while in the earth's orbit) and, having changed the flight trajectory, quickly disappeared from the field of view of the cameras.
The docking itself was successful in automatic mode, but after a while the engines of the module unexpectedly turned on. Because of this, the ISS turned 45 degrees.
Roscosmos decided not to create a commission to investigate the unscheduled switching on of the engines of the Nauka module, and the incident was explained by "a failure in the automatic control system."
What happened, only due to a coincidence of circumstances, did not end in tragedy - the destruction and de-orbiting of the International Space Station, which, under a certain set of events, could well have happened.
"Failure in automatic control systems", throughout the history of UFO sighting, can be said to be the "trademark" of UFO capabilities to disable various terrestrial control systems, engines, weapons systems (including underground launchers with strategic missiles).
The fact that this is not space debris is beyond doubt, since some debris dangling in orbit is unable to reduce or increase the speed of its uncontrolled flight, and even more so, is not able to change the flight trajectory with a simultaneous gain of speed.
It also cannot be a SpetsSKh satellite, simply for the reason that they are not able to perform such maneuvers and fly lower, in low orbit in groups.
This same object is single, but its shape is not known to us, it may be spherical or disc-shaped, but the fact that it is a controllable object in the earth's orbit, which is capable of changing the speed (significant acceleration) and flight trajectory, there is no doubt causes, all this is clearly visible in the video.
