When the person is long in space and it is not the gravitation of the earth, then returned to the planet he may experience serious problems with spatial awareness. With such negative effect at the time faced astronaut space Agency NASA drew Feustel back on solid ground after work on the International space station.
Shortly after the landing of the spacecraft “Soyuz MS-09”, delivered to the ISS Russian cosmonaut Sergei Prokopyeva, German ESA astronaut Alexander Gerst and NASA astronaut Serina Augen-Chancellor Feistel published in his Twitter a video where he literally re-learn to walk the earth.
In the video, the astronaut is trying to pass with my eyes closed in a straight line, getting used to gravity.
Welcome home #SoyuzMS09 ! On October 5th this is what I looked like walking heel-toe eyes closed after 197 days on @Space_Station during the Field Test experiment…I hope the newly returned crew feels a lot better. Video credit @IndiraFeustelpic.twitter.com/KsFuJgoYXh

“Welcome, “Soyuz MS-09″. So here, from heel to toe with eyes closed I went on 5 October after 197 days on the International space station. Hope, who had just returned members of the crew feel much better than I was then,” wrote Feistel.
The publication Mashable reports that the crew of the International space station spend every day two hours of physical training. They run on the treadmill, use the stationary bike, squat and so on. This is done in order to minimize the loss of muscle and bone, while people are in microgravity. But this does not mean that it will be easy to adapt to earth’s gravity.
Upon returning to Earth the astronauts and cosmonauts have to undergo physical and medical test in which doctors analyze how their bodies change during space flight.
For NASA, these data are of great value, because the Agency plans to send people to a longer space missions within the Solar system. If people ever want to go to the same Mars, scientists must first understand how the human body responds to a very long space flights, weightlessness and exposure to cosmic radiation.
