Have you ever witnessed a missile launch? Anticipation and expectation of the sight last much longer than the event itself.
Soyuz-U is a carrier rocket launched for 38 years. It is used to deliver different space vehicles to the orbit.
The space field Plesetsk hardly practices flights with people participation due to the location. The space field is the most northern and remote field in Russia. It’s much more expensive to launch rockets from here than from the equator.
A carrier rocket reaches the orbit in 8 minutes after launching.
What you see on the picture is not a cloud but a smoke demonstrating former presence of the vehicle. In some other minutes the smoke will fall onto the coast of the Arctic ocean.
The launching ground is ready to accept another rocket. The ground is never destructed by the vehicles and doesn’t need any reconstruction.
