After almost 9 months in space on Tuesday, March 18, the American astronauts is expected on Earth in the evening. What are the consequences for the human body of such a long journey? We explain to you.
The American astronauts Butch Wilmore and Sununi Williams will be blocked more than nine than nine than nine than nine than nine for nine at the International Space Station (ISS) and will finally return to Earth on Tuesday, March 18. As a memory, the duo should stay there for eight days at first. Due to failures and helium cots, which was noted on her bogry developed by Boeing, which was developed by Boeing, but had to empty the ship.
Osteoporosis, atrophied muscles
This long stay, which is not programmed, is not without consequences for these space drivers if the missions of the ISS take six months, but some astronauts can stay up to one year. In weightlessness or distance (the two terms mean the same) the human body floats and no longer has to be worn by the skeleton, which can even lie down by several centimeters before it is pounding again after a return to earth.

In space, the bones of the astronauts no longer regenerate, they widened and become more fragile (phenomenon of osteoporosis). “It is almost 20 years old in micropolas in micropolas, in terms of bone loss,” said the National Center for Room Studies (CNES). Also in the same tab atrophy the muscles and lose their mass.
In order to combat the lack of severity, astronauts must therefore perform two hours of physical activity per day on machines within the ISS. “The best proof of efficiency is that we have no breaking problem under astronauts if they return to the ground,” said AFP Rihana Bokhari, assistant professor at the Baylor College Space Medicine Center.

Balanced losses
The proper functioning of the inner ear is disturbed during a room stay. So much that astronauts experience balance of balance when they return to earth. “This happens to every astronaut, even those who only go to space for a few days,” said Emmanuel Urkequena, Professor of Aerospace Medicine at the University of Central Florida. Therefore, astronauts have to follow a specific editorial team of their body for 45 days as soon as their mission has ended.
Reduction within sight, reduced smell
How does it refer FranceinfoIn orbit, astronauts experience a decline in their olfactory capacities. The weightlessness that affects the eyeballs also have to wear glasses if they are in the ISS if they do not need them on earth. If you return to a fixed country, you have to get used to the feeling of friction on the skin because the clothes in the room float around the body.
