(CNN) – The first person to perform a space walk, Alexei Leonov, passed away this week. He was 85.
Though Leonov was not the first man on the moon, he earned his own “first” in the space race between the US and Soviet Union. On March 18, 1965, he embarked on the first spacewalk, spending 12 minutes outside the Voskhod 2 capsule.
The first American to walk in space, Ed White, would not do so until a few months later in June of 1965.
On the Apollo-Soyuz mission in 1975, Leonov met with US astronauts in space and gave TV viewers tours of their respective crafts, the first time Soviet and US cosmonauts collaborated in space. The mission is credited with kick-starting eventual international cooperation aboard the International Space Station.
Leonov’s funeral will be held on October 15 at Mytishchi Military Memorial cemetery outside Moscow, Russia.
