NASA astronauts Sunita Williams and Barry "Butch" Wilmore have safely returned to Earth following an unplanned nine-month mission aboard the International Space Station (ISS). Originally slated for just over a week, their stay was extended due to technical issues with their return spacecraft. Prolonged exposure to microgravity poses several health challenges, including bone density loss, muscle atrophy, cardiovascular deconditioning, vision impairment, and increased radiation exposure. To mitigate these effects, astronauts adhere to rigorous exercise regimens and undergo comprehensive medical evaluations upon return. Williams and Wilmore will now participate in a 45-day rehabilitation program to readjust to Earth's gravity and monitor potential long-term health impacts.
