The US space agency NASA has said that astronaut Sunita Williams and Buch Wilmore, stuck at the International Space Station (ISS) for more than nine months, will return to Earth on Tuesday evening. To bring back both astronauts, Elan Musk’s SpaceX launched the Crew-10 Mission on Saturday morning in collaboration with NASA. Both astronauts will be happy to return to Earth, but the changes in their body due to spending more than 9 months in space may take months to normalize.
Went to space station on 8 -day mission
Sunita Williams and Buch Wilmore will fly to the space station on an 8 -day mission on the 8 -day mission in June 2024, but they are still trapped due to technical fault in the aircraft. Both have been stuck in space for more than nine months and experts say that spending so long in space will bring major changes in the body of both astronauts.
Stay in space for nine months
After nine months in space, there are major changes in the body of astronauts. The biggest change is seen in muscles and bones, and they become weak. According to NASA’s astronaut Leroy Chiao, both astronauts will have difficulty walking after returning to Earth. Staying in space for a long time causes the problem of ‘baby feet’ among astronauts. He says that due to the absence of wind and gravity, astronauts experience weightlessness in space and disappear the thick skin of the upper part of their feet. Due to which their feet become very soft like young children and they have trouble walking.
Their bones weaken.
Another problem in front of astronauts is that due to lack of gravity, their bones become weak and the density of bones decreases. NASA says that from every month spent in space, the density of bones decreases by one percent, which increases the risk of breaking of bones.
Lack of physical activity also weakens the feet and back muscles. To prevent this, astronauts also exercise regularly for 2.5 hours at the space station. He regularly holds squats, deadlifts and bench pressings. A special place has also been built in the space station for this. Along with exercise, astronauts regularly run on the treadmill and also use exercise bikes. He also takes supplements to strengthen his bones.
What else do it affect the body?
Without gravity, the body’s fluids move upwards rather than down. This causes swelling on the face, increases pressure in the head and also affects the eyesight. Staying in space also affects the heart-prosperity system. The heart shrinks slightly and pumps blood at relatively slow. Because of this, there is a risk of cardiovascular problems after returning to Earth.
Staying isolated from the rest of the world for nine months with some astronauts also affects the mental health of astronauts. After going into space, there are changes in our brain due to which astronauts may face problems when returning to Earth.
