 The first human space walker could be answering your questions tomorrow. This is your space pod for March 18, 2015. Russian cosmonaut Alexei Leonov was the first human to set foot outside of his spacecraft on March 18, 1965. Since then, 732 spacewalks have been completed. Spacewalking is a pretty dangerous activity. Spacewalkers have to wear special pressurized suits to protect them from the harsh environment of space. On Alexei Leonov's very first spacewalk, his space suit malfunctioned and inflated like a balloon. He was unable to fit back inside the door to his spacecraft. Luckily, he was able to deflate part of the suit and get back inside. We've come a long way since then. But in 2013, astronaut Luca Parmitiano had to abort his spacewalk when his helmet started filling with water, causing him to go blind, deaf and hardly able to breathe. Spacewalking can give us many beautiful moments as well as scary ones. Spacewalkers have described the experience as phenomenal and that stars appear more brighter and more colorful and that they are able to fully appreciate both the beauty and the isolation of our planet. Alexei Leonov will be recounting his first spacewalking experience live on YouTube tomorrow, March 19th, 11am, Coordinated Universal Time. You can even submit your questions to Alexei using the hashtag on Twitter, Ask a Cosmonaut. Thank you to the Russian Space Agency Roscosmos for organizing this event that celebrates one of the greatest milestones of humankind. Thank you for watching this space pod.
