Scott Kelly's return from space after nearly a year aboard the International Space Station revealed the challenging effects of prolonged weightlessness. Despite being an experienced astronaut, Kelly experienced severe symptoms like dizziness, joint pain, and fatigue upon his return. The article explains how prolonged exposure to microgravity lengthens the spine and breaks down muscles and bones, necessitating regular exercise. Despite understanding these effects, the complexity of astronauts' adaptations and re-entry challenges underscores how difficult it is to return to Earth's gravity after extended missions in space.
Kelly had spent more time in space than almost any other person—four missions, each longer than the last, totaling five hundred and twenty days.
Despite being accustomed to space, Kelly noted, 'as I flew longer, the symptoms of returning to Earth were worse,' highlighting the complex effects of prolonged space travel.
