Astronauts Return from Nine-Month ISS Mission, Experience Severe Physical Changes

After an extended nine-month mission in space, NASA astronauts Butch Wilmore and Suni Williams have returned to Earth, facing a range of physical challenges due to prolonged exposure to microgravity. Studies reveal that astronauts experience significant physiological changes, including fluid redistribution leading to a 'moon face' appearance, blurred vision, and muscle atrophy. Upon re-entry, they may also suffer from dizziness, nausea, and other balance issues, necessitating a rehabilitation program similar to that for athletes recovering from injuries. Experts emphasize the importance of strict exercise regimens and nutritious diets to mitigate these effects during their time in space. As NASA continues to study these impacts, the insights gained may also benefit long-term hospital patients. The psychological toll of isolation and missing milestones on Earth is another crucial aspect of their experience.
