What challenges did astronauts face during their extended ISS stay?
During their nine-month stay on the ISS, astronauts Sunita Williams and Butch Wilmore encountered significant physiological challenges. Experts have noted concerns about muscle atrophy and bone density loss due to prolonged exposure to microgravity. Additionally, they faced psychological impacts upon returning to Earth, as readjusting to gravity can be difficult and may affect their ability to perform basic tasks.

How does prolonged microgravity affect the human body?
Prolonged exposure to microgravity can lead to various physiological changes in the human body. These include muscle atrophy, where muscles weaken and shrink, and bone density loss, which increases the risk of fractures. Other effects may include changes in vision and cardiovascular health, making it crucial for researchers to understand these impacts for future long-duration missions.

What psychological impacts do astronauts experience when returning to Earth?
Astronauts returning from long-duration missions often face psychological challenges as they readjust to life on Earth. They may experience difficulties with basic tasks and a sense of disorientation due to the sudden change in gravity. Understanding these psychological impacts is vital for supporting astronauts' well-being during their transition back to Earth.
