FIRST EVER SPACEWALK ON EXTREMELY RARE COLOR FOOTAGE

You’ve probably never heard of Alexey Leonov, but this Soviet cosmonaut is as much a part of human space history as Neil Armstrong. In 1965, Leonov was a member of the Voskhod 2 mission during which he conducted humanity’s first ever spacewalk. Put more dramatically, Leonov was the first human who chose to leave the safety of his ship and enter the endless void of space.

To celebrate the 50th anniversary of Leonov’s feat, color footage of him dangling perilously above the Earth in his primitive space suit has just been released. Check it out below. But fair warning. It’s pretty nerve wracking…

What you don’t see in the video above is what happened when Leonov tried to get back in to the ship.
