Astronaut wears a gorilla suit to the International Space Station ISS

NASA astronaut Scott Kelly once brought a costume as a gorilla to the International Space Station ISS.

Scott Kelly, was a NASA astronaut who worked on the International Space Station ISS on many missions. Recently shared video shows astronauts wearing gorilla costumes while working on the International Space Station ISS.

Video released by the US space agency NASA shows Scott Kelly dressed as a black gorilla floating in the zero gravity environment on the ISS.

It is known that the costume was a gift that Scott Kelly's twin brother gave him before boarding the station. Astronauts floating inside the International Space Station ISS and joking with other members.

The astronaut had a hard time convincing NASA to allow him to bring a gorilla costume to the space station because the process of controlling the carry-on of the ship was extremely tight.

One of Scott Kelly's missions aboard the International Space Station, which lasted for a year, was to study how the human body changes when living in zero gravity for long periods of time.

Astronaut Scott Kelly departed the space station on March 27, 2015, during which time Scott Kelly works out six days a week with the help of a treadmill, stationary bike, and resistance exercise machine.

After returning to Earth, on March 2, 2016, scientists conducted an examination to examine the effects on Scott Kelly's body in general and the heart in particular.

The team on Earth monitored Scott Kelly's twin brother Mark Kelly to see if there were any differences between the twins, one in space, the other on Earth.

Due to living in zero gravity aboard the International Space Station, the human body often undergoes a number of transformations such as swollen heads, atrophied legs, and bones becoming more brittle. In the results of the study, the scientists revealed that Scott Kelly's time in space caused the largest chamber in his heart to shrink, reducing its mass from 190 grams to 139 grams, a reduction of about 27%.

Mr. Scott lost his perception of speed and accuracy after returning to Earth. The scientists found that most of Scott's biological changes returned to normal after about six months back on Earth, with the exception of a few changes in the immune system and DNA.
