The launcher and its thermal protection.
Winter is coming, the snow has already fallen, people are putting on warmer clothes…
Rockets, like humans, also like heat. More precisely, not the entire launcher, but the satellites it puts into orbit.
In the cold season, in addition to the standard floor temperature control system of the upper composite, external thermal blankets are installed. This is a “warm sweater” made from pieces of insulating material, sewn exactly to the size of the headdress.
We look forward to Tuesday and the launch of the Soyuz with two Ionosfera-M satellites. Of course, it will fly away without the “jumper” – it will remain on Earth and will be useful for future launches.

The different pieces of the thermal “blanket” placed on the ground in the Vostochny MIK.
Thermal protection is implemented using an overhead crane.
Manual action is required to swaddle the upper composite.
