Awards and honors


After graduating from The Ohio State University College of Veterinary Medicine in June 1985, Linnehan entered private veterinary practice and was later accepted to a two-year joint internship in zoo animal medicine and comparative pathology at the Baltimore Zoo and Johns Hopkins University. After completing his internship, Linnehan was commissioned as a Captain in the U.S. Army Veterinary Corps and reported for duty in early 1989 at the Naval Ocean Systems Center, San Diego, California, as chief clinical veterinarian for the U.S. Navy’s Marine Mammal Program. During his assignment at the Naval Ocean Systems Center, Linnehan initiated and supervised research in the areas of cetacean and pinniped anesthesia, orthopedics, drug pharmacokinetics and reproduction in direct support of U.S. Navy mobile marine mammal systems stationed in California, Florida, and Hawaii.

NASA career

Selected by NASA in March 1992, Linnehan reported to the Johnson Space Center in August 1992 where he completed one year of Astronaut Candidate training, qualifying him for Space Shuttle flight assignments as a mission specialist. Linnehan was initially assigned to flight software verification in the Shuttle Avionics Integration Laboratory (SAIL). He was subsequently assigned to the Astronaut Office Mission Development Branch, working on payload development, and mission development flight support for future Space Shuttle missions. He first flew as a mission specialist in 1996 on STS-78, the Life Sciences and Microgravity Spacelab (LMS) mission. In 1998, he served as the payload commander on the STS-90 Neurolab mission. In 2002, he was a member of the four-man EVA crew on STS-109. A veteran of four space flights, Linnehan has logged over 59 days in space, including six EVAs (spacewalks) totaling 42 hours and 11 minutes. Linnehan was recently assigned to mission STS-123.

Spaceflight experience

STS-78 LMS (June 20 to July 7, 1996). The Life Sciences and Microgravity Spacelab mission was flown aboard Space Shuttle Columbia. The 17-day flight included studies sponsored by ten nations and five space agencies, and was the first mission to combine both a full microgravity studies agenda and a comprehensive life sciences payload. STS-78 orbited the Earth 271 times, and covered 7,000,000 miles (11,000,000 km) in 405 hours and 48 minutes.

STS-90 Neurolab (April 17 to May 3, 1998) was Linnehan's second Spacelab mission. During the 16-day flight the seven person crew aboard Space Shuttle Columbia served as both experimental subjects and operators for 26 individual life science experiments focusing on the effects of microgravity on the brain and nervous system. STS-90 orbited the Earth 256 times, and covered 6,300,000 miles (10,100,000 km) in 381 hours and 50 minutes. Both missions served as a model for future life sciences studies on board the International Space Station
