NASA's space craft Starline returned to Earth without passengers Sunita Williams and Butch Billmore. NASA decided to land Starline in the desert due to the dangers

Astronauts Sunita Williams and Wilmore are currently in the midst of an eight-month mission aboard the International Space Station. Their long time in a space-like environment presents unique challenges and health concerns, including a condition known as space anemia. This is a very dangerous disease. It occurs when astronauts experience a rapid decrease in red blood cells due to the accelerated destruction of these cells by the body in the absence of gravity 

On August 24, keeping in mind the safety of the astronauts, NASA decided to bring Starliner back to Earth without a crew. Wilmore or Sunita Williams will either stay at the Antrix station or will return in the future in 2025. Sunita Williams said that the muscle of the brain starts weakening in Antrix because there is no gravity here, due to which the spinal cord or other parts of the body (hair and nails) start growing rapidly. Due to the growth of the spinal cord, our height increases. At the same time, Sunita Williams also told that the density of our bones starts decreasing, due to which our muscles become weak, but all these changes are corrected on returning to Earth.
