Watch This Astronaut Chase His Crewmate in a Gorilla Suit

IN SPACE - MAY 29: In this handout provided by National Aeronautics and Space Administration (NASA), back dropped by planet Earth the International Space Station (ISS) is seen from NASA space shuttle Endeavour after the station and shuttle began their post-undocking relative separation May 29, 2011 in space. After 20 years, 25 missions and more than 115 million miles in space, NASA space shuttle Endeavour is on the last leg of its final flight to the International Space Station before being retired and donated to the California Science Center in Los Angeles.

Just because you’re an astronaut on a mission in the International Space Station doesn’t mean you can’t have a little fun.

Astronaut Scott Kelly showcased a pretty epic sense of humor when he donned a gorilla suit and chased his crewmate while in space, as reported by Space.com.

Kelly posted a video of the chase to his Twitter and Facebook, adding, “Needed a little humor to lighten up a #YearInSpace.” He continued, “Go big, or go home. I think I’ll do both. #SpaceApe.”

It’s proved pretty popular, too, garnering over 3,000 retweets and nearly 6,000 likes since going live on Feb. 23.

On Facebook, fans of Kelly’s were quick to praise his hi-jinx. “Who’d have thought that a gorilla outfit would be on the NASA packing list for #yearinspace? Very funny!” wrote on commenter.

The one-year mission will end upon Kelly’s return to Earth on March 1. Kelly traveled to the International Space Station to help with a study on how the human body is affected by spaceflight over a long period of time, as TIME Magazine has been reporting in a documentary.

Kelly’s shenanigans come as venture capitalists reportedly invested more in space startups in 2015 than in the previous 15 years combined, according to Fortune.
