There was a video from the onboard camera on a rocket launched from the Vostochny cosmodrome
It turns out that on the rocket, launched from the Vostochny, for the first time in the practice of the national astronautics, there was an onboard camera. And now, three weeks later, a video from her finally appeared:
In 2014, the European Space Agency, on its own initiative, bought an onboard camera and installed it on a rocket purchased from us, launched from the Kourou cosmodrome with the Sentinel-1a satellite. Now we can compare these frames:
And a small FAQ for questions that may arise when watching a video.
Why rocket turns in both videos?
Despite the fact that the rocket from afar seems symmetrical, for the control system it has a clear “top”, “bottom”, “left” and “right”. After launch, the rocket must turn into the so-called guidance plane. At Baikonur, the starting table rotates, because in the 50s analog systems could not spin so actively. On more modern launch sites in Kourou and on Vostochny there is no need to do this, the rocket turns itself. Depending on the position of the launching pad and the launching trajectory, the angle of rotation may be different, judging by the video for launching on very similar sun-synchronous orbits with an inclination of 98 ° for the Kuru, this turns out to be approximately 90 °, on the Vostochny area around 180 °.

Why, after the separation of the first stage (four “carrots”), their tips are wrapped in flame?
After separation, the first stage opens the drain valves of the oxidizer (liquid oxygen), and the oxygen escaping under pressure ignites the unburned fuel, it is slightly in excess in the exhaust gases.
Why does the camera begin to rotate immediately after the removal of the removal unit?
Because almost immediately after separation at the third stage, the oxygen drain valve also opens, and it starts to go to the side. And the release of pressure ensures that the third stage does not explode while it is in space for several days.
Cameras found on fallen stairs?
No, the camera was transmitting data by radio. I suspect that out of reinsurance (what if with a rocket what will happen?) The picture was not transmitted on the air right away.
How necessary is such a camera?
Mainly they are needed for PR and beautiful pictures, the flight parameters are much more convenient to receive from telemetry.
