I was enjoying some 2017 April 13 tweets on robots and reminiscing about shoveling snow after seeing this one, but then I scrolled down further and saw a video of a rocket. It's also here in YouTube, where the information seems to say it is the first launch from Vostochny Cosmodrome.
edit: The time line is not 100% clear - there is dry snow on the ground in the screen shots shown below, but by the time the actual launch happens, there is no snow, nor wet ground where it would have melted recently. The screen shots at the bottom clearly show different weather and different fairing covers - it looks like these are two different days. However, my question is simply about the need for insulation.
Perhaps the screenshots below really represent a "dry run" — testing and preparation for this launch?
It is certainly a "cool" video (manage your volume, there is a sound track) but is the Amur Oblast really colder than (a spacecraft might become when it is in) space? Or have I got it wrong, and the payload is pre-cooled cryogenic and the local ambient is actually too hot?
