KENNEDY SPACE CENTER, Fla. (CASIS PR) – In the absence of effective countermeasures, prolonged spaceflight can result in many of the same physiological changes associated with aging—bone loss, muscle deterioration, and altered immune system function—only at a much quicker rate. This makes the microgravity environment of the International Space Station (ISS) a valuable platform for research on conditions associated with the aging process.

Commercial Space Travel Carries Implications for Health

By Leland Kim

Just a half-century after the first human ventured into space, commercial space travel — or “space tourism” — is quickly becoming a reality. A new UCSF study looks at the health implications of flying into outer space and suggests establishing health screening standards for private citizens who want to blast off.

“We all have questions from patients related to air travel,” said lead author S. Marlene Grenon, MD, MS, assistant professor of surgery at the UCSF Division of Vascular and Endovascular Surgery, and a researcher at the San Francisco VA Medical Center. “In the short future, we may be getting questions from our patients about space travel.”
