Soyuz TMA 09M redocking video

This is a pretty mesmerizing video so I wanted to share it with you.

Thanks for this.

really cool

That was beautiful !

Beautiful orbital dance Flying in space =\= flying in atmosphere - such videos drive this fact home better than any amount of theoretical knowledge.

The rotation angle isn't very important when docking because the probe-and-drogue docking system rotates the vehicle to the correct angle as soon as it latches.

This is really cool!

It's sped up 4x according to the youtube description.

Another question: At the moment of undocking: It's docking module pushed them apart that hard or they stepped on RCS?

And another question: video is accelerated? How much?

they generally try to avoid firing rcs (especially the ones who would be firing more towards the space station, like the ones needed for reverse) when this close. (simply to limit the risks of contaminating the science equipments attached outside ISS with the rcs exhaust gases), so there's a good chance they have something like a spring release  (said spring would be compressed during docking, both to absorb the docking impact before locking, and to push back the spacecraft when undocking)

Also, does anyone else see the ripped radiator at 4:59?

Yea the ripped radiator and it seems to be blowing in the "wind" which I'm thinking is from the RCS of the Soyuz.

I was wondering if it was flapping because of the coolant being circulated through the structure.

Lajoswinkler said this in the youtube comment section about the flapping radiator:  "It's one of the station's radiators. It's loosened and it swings like a pendulum in vacuum. ISS is not a rigid object and docking and undocking procedures cause mechanical vibrations of the whole structure which gets visibly amplified on such thin, wide, loosened things. The only thing stopping it is internal friction. Just like with flags in vacuum. They will flap and swing around."

It could be amplified by RCS, but I still think there is a certain degree of internal vibrations of the station that get visibly magnified on small flappy objects.
