NASA has released a video showing astronaut Dreyo Fustel, unable to walk in a straight line with his eyes closed, after returning to Earth, ending his 200-day stay at the International Space Station (ISS) with his colleagues.
Space scientists who spend months at the ISS are influenced by their position in a gravitational position, Sky News reported on the site.
Astronomers usually need two hours of exercise each day to maintain the health of their muscles and bones because they are not used in space, where there is no gravity and where astronauts are moving as if they were flying.
Space scientists are forced to do a number of exercises and medical examinations when they return to Earth, in order to be able to recover from the impact of extraterrestrial life.
