The reason for the astronaut needs to move by stretcher when returning to the earth

On March 18, two Astronauts Nasa Sunita Williams and Butch Wilmore landed in the ocean in SpaceX’s compartment, ending for more than 9 months in the space instead of a few weeks as expected. When the train compartment is open, it is likely that the astronauts will be taken out and put on the stretcher. The reason is not related to the duties of Williams and Wilmore on the International Space Station (ISS), which is the issue that all astronauts must follow, according to, according to Live Science.

When the astronaut returned to the earth from the universe, they could not immediately walk after landing. This is due to temporary changes to the body that occurs in space, forcing NASA to handle with a strict safety process.

“Many of them do not want to lie on the stretcher, but they are required like that,” said John Dewitt, director of the Sports Science Applied at Rice University at Texas. He used to work in NASA’s Johnson Space Center and developed a method of improving the health of astronaut during space flight.

Like people who are hangover due to the movement of the roller or on the ship when the sea is moved, the astronaut can experience the feeling of dizziness and nausea when returning to the Earth. For this reason, astronaut is usually placed on the stretcher after landing as a precaution. This temporary feeling occurred due to the human body designed to take advantage of the downward force on Earth as gravity. However, the spatial environment on orbit such as the ISS station creates a feeling of non -weight for the astronaut inside the station, motivating their bodies to adapt to the changing environment.

An important change occurs in the vestibular system in the inner ear, playing a key role in maintaining balance, according to Dewitt. In the space, this system has acquainted with some sensory information when the brain adjusts to the non -weight environment. Therefore, when the astronaut returns to the Earth and is influenced by gravity, they must adjust again, temporarily causing “drunkenness of space movement”.

Another change that the astronaut experienced, especially those who stay in the space, is a reduction in bone density and muscle atrophy. While walking on Earth is enough to maintain healthy muscles thanks to gravity, astronauts in space do not need much muscle use. The little activity causes muscles to weaken and atrophy over time, leading to muscle weakness. To solve this problem and other effects related to space flights, long -term astronauts in the universe like Williams and Wilmore must follow the daily training regime daily by the station on the station.

Williams and Wilmore are members of the Crew-9 mission with Nasa Nick Hague and Astronaus Roscosmos Aleksandr Gorbunov, all will return to Earth on SpaceX’s Dragon spacecraft on March 18. For Williams and Wilmore, the flight will end their 9 -month long -term mission after the Boeing Starliner ships carrying them to encounter some problems on the Journey to the ISS station, including pushing motor problems and fuel leaks, so they must fly back to Earth with vacant compartments. Despite malfunctioning, the two astronauts still kept their positive spirit and believed they did not have any serious problems even for a long time on the ISS station.
