Ohio State College of Veterinary Medicine alumnus and NASA Astronaut Dr. Rick Linnehan (DVM 1985) has practiced zoo, exotic and marine mammal medicine and has also logged almost two months of space flight time aboard the space shuttles Columbia and Endeavour and the International Space Station. Some of his most important contributions to science have been in space medicine and physiology as well as extra vehicular activity (space walking) on a Hubble Space Telescope servicing mission and a construction mission to the International Space Station.
Rick participated in groundbreaking biomedical studies while part of the Neurolab and Life Science-Microgravity Spacelab missions as both a researcher and a test subject. The results of those seminal studies have contributed to our knowledge about bone and muscle atrophy, disturbances of sleep and balance, and functioning of the nervous and cardiovascular systems.
