For several days before launch astronauts and cosmonauts are quarantined to ensure they don’t get sick with a cold or other communicable disease during their flight.
Astronauts and cosmonauts have superstition based traditions that trace back to the first people to fly in space.
For cosmonauts, that would be Yuri Gagarin. As Yuri walked to his rocket, the chief engineer gave him a smack on the rear end. That practice is still followed. Yuri also took a leak on the tires of the bus that took him out there. That tradition is still followed (by male cosmonauts and astronauts).
对于俄罗斯宇航员，那将是尤里·加加林。 当他走向火箭时，总工程师在最后一刻拍了他一下。 这种做法仍被遵循。 尤里还在把他带到那里的公共汽车轮胎戳漏了气。 仍然遵循这一传统（男性俄罗斯宇航员和美国宇航员）。
Another tradition for cosmonauts, although it doesn’t go back to Yuri, is to watch the film White Sun of the Desert the night before launch. Another more recent tradition is that a Russian Orthodox priest will bless the crew with water.
For NASA astronauts, the traditions go back to Alan Shepard. Alan had scrambled eggs and steak for breakfast, the day of his flight, so most astronauts do today.
对于NASA宇航员而言，传统可以追溯到Alan Shepard。 在飞行的那天，艾伦（Alan）曾将鸡蛋和牛排炒作早餐，所以今天大多数宇航员都这样做。
I wonder if Alan Shepard knew he was making a meal selection for future generations of astronauts, or if it was just breakfast to him.
“There’s the slight chance I’m going to explode, I might as well eat a steak” was probably what’s on his mind hahah
So many superstitions for people of science? Wow…that is weird!!!
I’ve spent my life surrounded equally by scientists and non-scientists and have noticed no significant difference between their levels of superstition.
