From the consecration of the rocket by the Orthodox priest to the "toilet" pause at the right rear wheel - all astronauts going to the International Space Station, follow a variety of traditions and superstitions, the main of which arose in the USSR, at the time of Sergei Korolev. The strangest space launch rituals It should be noted that not all traditions are listed here.
I guess having that much rocket fuel attached to your ass..............can't hurt to do the rituals..........LOL
