Astronaut Scott Kelly Once Brought A Gorilla Suit Onto The International Space Station

People are going wild over a resurfaced clip of astronaut Scott Kelly getting into a gorilla suit that he managed to get onto the International Space Station.

Footage released by NASA in 2016 showed Kelly getting into the suit that his twin brother Mark gifted him, and did so without warning the other astronaut onboard.

He burst out of the large, white bag before gliding through the zero-gravity environment on the ISS.

Hilariously, he managed to find a crew member and chased him through the station.

It was a huge moment six years ago and people have been able to enjoy it all over again after it was posted on Reddit.

One person responding to the video said: "Do you want ejected from the airlock? Because this is how you get ejected from the airlock..."

Another added: "The part that gets me is how the dude running away flails his arms trying to 'swim' faster. In most videos of astronauts doing things (and not panicking), they know that swimming in air doesn't do much."

A third wrote: "He's one of the most experienced and respected astronauts since the days of Neil Armstrong, I can see how he'd be given an exception to do something like this."

Who knows how the Kelly brothers managed to convince NASA to let the gorilla suit onboard the tightly-controlled luggage department but it was clearly worth it.

Scott Kelly was onboard the International Space Station for a year to see how the human body can handle 'ultra-long spaceflight', according to Space.com.

It certainly wasn't the first time such a lengthy spaceflight had been performed, but Scott and Russian cosmonaut Mikhail Kornienko were there specifically to research how their body and, more specifically, their genetics coped in a zero-gravity setting for so long.

The team on Earth also monitored Scott's twin brother Mark to see whether there would be any differences between the two astronauts when the former returned.

Interestingly, there were more than 1,000 genes that had chemical markers than weren't present in his pre-flight tests.

The tests also discovered Scott's telomeres, which are caps that sit on the ends of our DNA strands, were longer than before he left, which was opposite of what researchers were expecting. They eventually returned to pre-flight levels in about 48 hours.

Let's just hope we get to see more hilarious pranks like the gorilla suit in the years to come.
