Indian -origin astronaut Sunita Williams and her partner Buch Wilmore are scheduled to return to Earth on March 19 after spending nine months in space. Space-X spacecraft has reached the International Space Station (ISS) to bring them back. A new batch of astronauts has been sent to take their place there. These include NASA's Anne McClane and Nicole Airte, Japan's Takuya Onishi and Russia's Kiril Peskov. While McClane and Airters are military pilots, Onishi and Peskov have been former airline pilots.
After Sunita Williams and Buch Wilmor return, these astronauts will stay on ISS for the next six months. Sunita and Buch left for the international space station on an eight -day mission. However, a technical fault occurred in Boeing's Starlineer vehicle. Due to this, he had to stay at the space station and his mission increased for about 270 days.
After being in space for nine months, Sunita Williams and Buch Wilmore are finally going to return to Earth on 19 March. However, due to staying without gravity in space for so long, it can affect their body. According to scientists, they can struggle with a problem called 'baby feet', which can affect the structure of their feet.
What is a 'baby feet' problem?
Staying in microgravity for a long time does not weigh bones and muscles, causing them to weaken. After returning to Earth, they may have difficulty walking, because it will take time for the legs to resolve the gravity again.
Due to lack of gravity in space, the bones and muscles of the body are affected. The density of bones carrying loads on Earth is reduced by about 1% every month. If the right diet, exercise and medicines are not consumed, then it can make the bones weak and brittle. This process is called 'atrophy'. According to NASA, they exercise an average of two hours every day to protect astronauts from this effect.
Muscle weakness and fatigue
The muscles in space do not have to function normally, making them weakened. After coming back, Sunita may also feel fatigue and weakness in normal activities.
Dizziness
The internal balance system of the ear is affected due to microgravity. On returning to Earth, they may have problems of dizziness, nausea and imbalance.
Blood circulation and heart problems
In space, the heart does not have to work hard to pump blood. In such a situation, after returning to Earth, there may be a decline in blood pressure, which can cause dizziness as soon as standing.
Effect on immune system (immune system)
According to some studies, staying in space can weaken the immune system. This can cause problems like infection or allergy to Sunita.
How will the recovery process be done?
After the return of Sunita and Buch, they will have to go through a special rehabilitation process. This will include physiotherapy, exercise, balanced diet and medical surveillance. The NASA medical team will ensure that they can return to normal condition as soon as possible.
Staying in space for such a long time, Sunita and Buch's families have also been affected. Wilmore's wife and two daughters and Sunita's husband and her mother are eagerly waiting for her return. Wilmore, who is a church Elder, is again eager to join face to face religious services. At the same time, Sunita is waiting for her two Labrador dogs to take a walk. Now everyone's eyes are fixed on March 19, when both these astronauts will come back safely to the earth.
