Astronauts face several challenges in space, including exposure to microgravity, which can lead to muscle atrophy and bone density loss. They also contend with radiation levels that are much higher than on Earth, increasing their risk of cancer and other health issues. Additionally, the isolation and confinement of living in a spacecraft can affect their mental health, leading to stress and anxiety. Finally, the technical complexities of operating spacecraft and conducting experiments in a zero-gravity environment require extensive training and adaptability.
John Glenn faced challenges with overcoming a fear of failure, dealing with the mental and physical strain of space travel, and managing the high-stakes nature of his missions. Despite these difficulties, Glenn became the first American to orbit the Earth and later returned to space as the oldest person to fly in space.
