The astronauts are in perfect health, but the return to Earth will have to practice walking like this.
No one is saying that getting used to life on Earth after a long stay in space is a simple thing. Although they are very healthy to qualify as an astronaut, when they return to Earth after a mission to the International Space Station, they will exhibit many symptoms that prevent them from functioning normally due to the experience. Over a long period of adaptation to outer space and loss of consciousness of terrestrial space.
According to a video recently shared by NASA astronaut Drew Feustel, one of the symptoms is not being able to go in a straight line with your eyes closed. The person in the video is Feustel’s colleague, who is also an astronaut when he returned to the ground from the space station on Tuesday. Feustel herself experienced the same symptoms when she returned to Earth in October.
“This is exactly what happened to me on October 5 during the experimental exercises while walking with my eyes closed after 197 days on the International Space Station.” – said Feustel.
Astronauts typically train about 2 hours a day to maintain muscle mass and bone density in microgravity, but that doesn’t mean that returning to the ground will be normal.
Upon their return to Earth, astronauts undergo a series of physical exercises and medical examinations to see what their bodies look like after spending time in space.
If we are to send people to Mars, scientists need to know exactly how the human body reacts to a long period of weightlessness and its ability to withstand radiation exposure. Therefore, this data is extremely important to NASA and it is used to improve the tools that help astronauts live longer in space and participate in missions longer.
