Sunita Williams and Buch Willmore News: It is fun to see astronauts floating in the air at the international space station, but due to lack of gravity there, they will have to face many difficulties while returning to Earth. They face volatility, dizziness, speaking and walking difficulty. NASA astronaut Sunita Williams and Buch Willmore and Russian astronaut Alexander Gorbunov returned to Earth on Wednesday from SpaceX Dragon Space Experience (Capsule).
The risk of adverse effects on bones and muscles
The biggest concern about Sunita Williams and Buch Willmore is that their bones and muscles are now weakening. ISS But astronauts float in microscopy, which has an effect on their body. Our body always has to work against gravity on Earth, due to which our muscles and joints are constantly exercising, but in space, the density of muscles and bones starts decreasing without any obstruction, because the body does not have the strength to lift its weight. Astronauts may lose 1% of their bones every month. Especially in waist, hips and thigh bones. This increases the risk of bones breakdown after returning to Earth. In addition, their height increases by 1-2 inches due to long spinal cord of astronauts. However, when returning to Earth, this height ends.
Wilmore and Williams were launched from Cape Canaveral on 5 June last year through Boeing’s new Starlineer Capsule. Both went on the mission within eight days. But due to helium leakage and slow speed of spacecraft, he remained stranded in the space station for about nine months.
Sunita Williams and Buch Wilmore will face the same challenges as all astronauts that spend longer in space. They will have difficulty in walking and will also have trouble watching. You will get dizzy There will be instability in the movement.
They will have trouble with baby-legs. The baby feet are the soles of the feet of astronauts where a large part of the skin descends. Therefore, the soles of their feet become soft like the soles of very small children (newborns).
Doctors at Houston -based Bayler College of Medicine say that when astronauts return to Earth, they have to deal with gravity. He has difficulty in walking. In addition, it is also difficult to keep your vision stable. Walking is definitely a problem. But they also have difficulty in standing after sitting. Therefore, after reaching Earth, the astronaut is immediately placed on the wheelchair. But how many weeks does an astronaut take life on earth? The problem is that the fluid present in the vestibular part of the ear helps the animal (human) to keep its body balanced.
Japanese Space Agency J.O. Giving this information, X said that the information obtained from vestibular organs also changes. Therefore, the brain becomes confused. Space is coming. Therefore, sometimes gravitational disease also occurs. Its symptoms are similar to space-disease.
Gravity draws the fluid of the body downwards. But there is no gravity in space. Thus these fluids reach the upper part of the body. Thus, people who live in space for a long time have to face many difficulties.
