Top 20 Longest Spacewalks in History

Spacewalking or Extravehicular activity (EVA) is any activity done by an astronaut or cosmonaut outside a spacecraft beyond the Earth’s appreciable atmosphere (a moonwalk is also an EVA). The first skywalker was the Soviet cosmonaut Alexey Arkhipovich Leonov. He became the first human to conduct an extra-vehicular activity (EVA) on March 18, 1965; exiting the capsule during the Voskhod 2 mission for a 12-minute spacewalk. Since this very short EVA, a lot of astronauts/cosmonauts spent many hours outside their spacecraft, mostly for maintenance missions. Here are the top 20 longest spacewalks in history.

There’s a Memorial to Fallen Astronauts on the Moon

On August 2, 1971, during the third EVA (Extravehicular activity) of Apollo 15Notes 1 mission, commander David Scott drove the rover away from Lunar Module, where the television camera could be used to observe the lunar liftoff. Then he left a small aluminum statuette called “Fallen Astronaut” next to the rover, which commemorates those astronauts and cosmonauts who lost their lives in the pursuit of space exploration. Scott also left a plaque bearing the names of 14 known American astronauts and Soviet cosmonauts deceased by that time, along with the statuette. The names of Astronauts and cosmonauts were inscribed in alphabetical order on the plaque.
