William E. Thornton (April 14, 1929 – January 5, 2021) was an American physician, engineer, and NASA astronaut. He was born in Faison, North Carolina, and played a significant role in the development of medical devices and exercise equipment for spaceflight. Thornton's contributions to space medicine and his efforts to mitigate the effects of microgravity on the human body have had a lasting impact on space exploration.

Early Life and Education

William Edgar Thornton was raised in Faison, North Carolina. He pursued his higher education at the University of North Carolina at Chapel Hill, where he earned a Bachelor of Science degree in physics. Thornton continued his studies in medicine and received his M.D. from the University of North Carolina at Chapel Hill in 1963. His interest in the intersection of medicine and physics led him to a career that would eventually take him to the stars.

NASA Career

Thornton was selected by NASA in 1967 as part of Astronaut Group 6, also known as "The Scientists." His selection was part of NASA's effort to include scientists and physicians in space missions to conduct advanced research. Thornton flew on two Space Shuttle missions: STS-8 aboard Challenger in 1983 and STS-51-B aboard Challenger in 1985. During these missions, he conducted numerous experiments in space medicine, focusing on the physiological effects of spaceflight on the human body.

One of Thornton's significant contributions to space exploration was the development of the Space Shuttle In-flight Treadmill (S-T), which allowed astronauts to exercise in space to counteract the effects of muscle atrophy and bone density loss caused by prolonged exposure to microgravity. He also developed a device to measure body mass in a weightless environment, an essential tool for monitoring astronauts' health on long-duration missions.

Post-NASA Career

After retiring from NASA, Thornton continued to work on medical and physiological research related to spaceflight. He held several patents for his inventions and was a sought-after speaker on space medicine and the challenges of human space exploration.

Legacy

William E. Thornton's work has had a profound impact on how astronauts maintain their physical health in space. His inventions and research have paved the way for safer, longer-duration space missions, contributing to the success of the International Space Station and future missions to Mars and beyond. Thornton's legacy is not only in the equipment he developed but also in his vision of integrating medical science with space exploration to ensure the well-being of astronauts.

Death

William E. Thornton passed away on January 5, 2021, leaving behind a legacy of innovation and exploration. His contributions to space medicine continue to benefit astronauts and space missions, ensuring that human health remains a priority in the quest to explore the final frontier.
