NASA Astronauts Wilmore and Williams Return After Nine-Month Mission due to Starliner Issues: Impact of Prolonged Space Travel

Two NASA astronauts, Barry "Butch" Wilmore and Sunita "Suni" Williams, have returned to Earth after an extended nine-month mission on the International Space Station due to issues with the Starliner spacecraft. Spending a prolonged period in space can bring about significant changes to human physiology and psychology, according to experts.

Microgravity in space can lead to a decrease in muscle mass and bone loss, while space radiation poses risks such as radiation sickness and increased cancer risk. Isolation in space also has physical and psychological effects, highlighting the importance of creating a healthy environment for astronauts on long-duration missions.
