The Dragon spacecraft will take a splash down in the sea near the coast of Florida at 3.27 minutes on the morning of 19 March. However, re -entering the Earth’s atmosphere is one of the most dangerous stages of space travel. According to NASA, as soon as a spacecraft enters the atmosphere, it has to face extreme conditions. He has to withstand temperatures up to 7,000 degrees Fahrenheit. During this time, the spacecraft will enter the earth’s air circle at a speed of more than 22 times at the speed of sound. For this reason, astronauts sitting inside will have to face tremendous pressure and tremors.
The crew dragon spacecraft will open two parachutes one after the other to slow down its speed while landing on the earth. If everything is according to the plan, the capsule will come at a speed of 20 mph (32 kmph) at a orbital speed of more than 17,000 mph (27,359 kmph). After this, he will fall into the sea on the Florida coast.
How will the health of Sunita Williams be
However, troubles will not end here. Even if the landing is successful, even if his bones and muscles have become weak due to staying in space for so long. Their eyes can go or weaken.
These threats will only grow when humanity will move further in the solar system, including Mars, which will demand innovative solutions to protect the future of space exploration.
What will be the problems after returning to the earth
Rihanna Bokhari, assistant professor at the Space Medical Center of Bayler College, said that even though Sunita Williams and Buch Wilmore’s visit had been very popular, it is a common thing. ISS missions usually last for six months, but some astronauts live there for a year. Researchers are confident that they are able to maintain the health of the astronaut during that period. Most people know that lifting weight strengthens muscles and bones. The normal act on the earth also resist gravity and bones work from it, but gravity is not present in the orbit. To fight this, astronauts use three exercise machines on ISS.
This danger too
A two -hour workout daily keeps them fit. Bokhari said, “We have the results that when astronauts return to the earth, they do not have a fracture problem. However, the loss of bones in the scan can still be detected.” Emmanuel Ukiketa, vice -president of aerospace medicine at the University of Central Florida, said that the problem of hearing is also with every astronaut. Calcium levels in their urine may increase, which may increase the risk of kidney stones.
