The First Spacewalk - March 18, 1965


Hi Everyone I'm eaves and you're listening to this day in History Class. A podcast where we build the time machine and all you have to do is hop. Today IS MARCH. Eighteenth Twenty twenty. The day was March. Eighteenth nineteen sixty five so viet cosmonaut. Alexey Leonov became the first person to go. On a spacewalk spacewalk is one in astronaut leaves their spacecraft to a tether it's called EDA which stands for extra vehicular activity. Alexi Leonov served as a fighter pilot in the nineteen fifties by nine hundred sixty. He had been chosen as one of the first twenty cosmonauts for the Soviet space program and was training to take his first spaceflight. The Soviet Union launched the first person to space when Yuri Gagarin's made an orbital flight. And His boss doc wine spacecraft in nineteen sixty one the. Soviet program launched is first mission on October twelfth. Nineteen sixty four. Both hide one was the first to carry more than one crew person into space. It was also the first mission to carry an engineer and a physician into space hot. Too launched just months later on March eighteenth nineteen sixty five it carried to people commander Pal Bouillon and pilot Alexi. Leonov it was Leonov's first spaceflight and billiards first and only spaceflight the hard three K. D. space craft had an extendable airlock that allowed enough to go out into space without having to evacuate the main cabin air about an hour and a half after lines billions of open the outer airlock and Leonov walked out into space. Attached to tether his spacewalk lasted for about twelve minutes. A camera mounted on the airlock recorded the spacewalk. It was reported that Leonov's body temperature jumped about three point two degrees Fahrenheit or one point eight degrees Celsius twenty minutes and he was close to having a heat stroke. His spacesuit was full of sway. Though the spacewalk went relatively smoothly Leonov had difficulty reentering. The capsule the pressure difference between the air and his spacesuit and the vacuum of space expanded and stiffened his spacesuit that made it to big heart to fit back into the airlock so Leonov opened a valve to release oxygen and depressurize his suit. He was then able to fit back into the space craft but he did start to feel some of the effects of decompression thickness namely the sensation of pens and needles. The crew. Hit another snag when objecting inflatable airlock. Which sent the spacecraft into a Spin? Oxygen levels also began to climb which came with the risk of explosion. On top of this the automatic guidance system for re entry malfunctioned. They had to turn off the automatic landing program and instead conduct re entry and landing manually. The ended up off course and the orbital module did not separate from the landing module. They landed in snow in a forest in Siberia. The
