The return of Indian-American astronauts Sunita Williams and Butch Wilmore from the International Space Station (ISS) has been postponed. NASA has postponed Mission Crew 10, which was carrying a new crew to the space station, due to technical problems.

At present, no latest information has been revealed about his return. It is being said that after returning to Earth, there may be some changes in his body. He may face some discomfort in walking back on the ground.

Why do changes occur in the body after returning to Earth?

• Both of them have spent 9 months in space, so it is not easy for them to adjust to the Earth's gravity.
• Former NASA astronaut Leroy Chiao said about this, this happens because you are unable to maintain balance.
• He said astronauts who stay in space for a long time develop baby feet after returning to Earth, that is, they lose the calluses on the soles of their feet that hold them together for walking.
• "You lose a lot of the thick skin on your feet. So when you come back, you have what look like baby feet," Chiao said.
