VIDEO : NASA Astronaut Monkeys About Aboard ISS

INTERNATIONAL SPACE STATION (STORYFUL) - Scott Kelly of NASA is coming to the end of a year-long mission aboard the International Space Station. And, perhaps, it's not a moment too soon.

As this video shows, Kelly has begun monkeying around aboard the ISS of late. As he wrote himself on Twitter, where he posted this video, he "Needed a little humor to lighten up a #YearInSpace."

The video shows British astronaut Tim Peake being chased through the ISS by Kelly, dressed as a gorilla.

The gorilla suit was a birthday gift sent to Scott Kelly by his brother, the retired astronaut Mark Kelly.
