In February 2021, winter survival training was organized for two conventional crews. The first included Roscosmos cosmonauts Oleg Kononenko, Nikolai Chub and instructor of the Cosmonaut Training Center Dmitry Zakotenko, the second – Roscosmos cosmonauts Denis Matveev, Andrey Fedyaev and Anna Kikina.
Oleg Kononenko and Nikolai Chub practiced their skills according to an abbreviated program. Together with the instructor, they spent 9 hours in the forest – this is the duration of the crediting training for their crew. The cosmonauts had enough time to successfully complete the actions necessary to survive in the winter in a wooded and swampy area. And although Nikolai Chub has not yet been in space, he gained the experience of “winter survival” on repeated previous trainings. If he and Oleg Kononenko had a break between tests in the forest for five years or more, this crew would have spent at least two days in natural conditions.
According to Viktor Ren, such trainings have another purpose – to test cosmonauts for psychological compatibility.
If the first conventional crew “survived” in the daytime, when the air “warmed up” to minus 12 degrees, then the second crew (Denis Matveev, Andrey Fedyaev, Anna Kikina) had two days in the forest, and frosts these days stood stronger.
