Sunita Williams and Butch Wilmore traveled to the International Space Station (ISS) last year for an eight-day mission. However, due to technical issues, they have been stranded in space for nine months.
NASA’s Crew-10 launched from Florida’s Kennedy Space Center last Friday, heading toward the ISS to bring new astronauts and return Williams and Wilmore to Earth.
However, after such a prolonged stay in space, they may face several physical challenges upon returning. One significant issue is the softening of their feet, a condition known as “baby feet.” In space, astronauts do not walk, so their feet do not experience the usual friction and pressure, causing the thickened skin on the soles to wear off. Once back on Earth, it may take weeks or even months for their feet to readjust, making walking difficult.
Another major concern is bone density loss. According to NASA, astronauts can lose about 1% of their bone density per month if proper countermeasures are not taken. Additionally, muscle strength weakens in space due to the absence of heavy physical activities.
The cardiovascular system also undergoes changes. Without gravity, the heart does not need to pump blood as forcefully, leading to reduced circulation. This can increase the risk of blood clotting and fluid imbalance in the body.
NASA will closely monitor the astronauts’ health after their return to help them recover from the effects of prolonged weightlessness.
