Catherine Coleman

Catherine Grace "Cady" Coleman (born December 14, 1960) is an American chemist, engineer, former United States Air Force colonel, and retired NASA astronaut. She is a veteran of two Space Shuttle missions, and departed the International Space Station on May 23, 2011, as a crew member of Expedition 27 after logging 159 days in space.

Coleman graduated from Wilbert Tucker Woodson High School, Fairfax, Virginia, in 1978. In 1978–1979, she was an exchange student at Røyken Upper Secondary School in Norway with the AFS Intercultural Programs. She received a B.S. degree in chemistry from the Massachusetts Institute of Technology (MIT) in 1983 and was commissioned as graduate of the Air Force Reserve Officer Training Corps (Air Force ROTC)., then received a Ph.D. degree in polymer science and engineering from the University of Massachusetts Amherst in 1991. She was advised by Professor Thomas J. McCarthy on her doctorate. As an undergraduate, she was a member of the intercollegiate rowing crew and was a resident of Baker House.

Coleman continued to pursue her PhD at the University of Massachusetts Amherst as a second lieutenant. In 1988, she entered active duty at Wright-Patterson Air Force Base as a research chemist. During her work, she participated as a surface analysis consultant on the NASA Long Duration Exposure Facility experiment. In 1991, she received her doctorate in polymer science and engineering. She retired from the Air Force in November 2009 as a colonel.

Coleman was selected by NASA in 1992 to join the NASA Astronaut Corps. In 1995, she was a member of the STS-73 crew on the scientific mission USML-2 with experiments including biotechnology, combustion science, and the physics of fluids. STS-93 was Coleman's second space flight in 1999. She was mission specialist in charge of deploying the Chandra X-ray Observatory and its Inertial Upper Stage out of the shuttle's cargo bay.

Coleman served as Chief of Robotics for the Astronaut Office, to include robotic arm operations and training for all Space Shuttle and International Space Station missions. In October 2004, Coleman served as an aquanaut during the NEEMO 7 mission aboard the Aquarius underwater laboratory, living and working underwater for eleven days.

Coleman was assigned as a backup U.S. crew member for Expeditions 19, 20 and 21 and served as a backup crew member for Expeditions 24 and 25 as part of her training for Expedition 26.

Coleman launched on December 15, 2010 (December 16, 2010 Baikonur time), aboard Soyuz TMA-20 to join the Expedition 26 mission aboard the International Space Station. She retired from NASA on December 1, 2016.

STS-73 on Space Shuttle Columbia (October 20 to November 5, 1995) was the second United States Microgravity Laboratory (USML-2) mission. The mission focused on materials science, biotechnology, combustion science, the physics of fluids, and numerous scientific experiments housed in the pressurized Spacelab module. In completing her first space flight, Coleman orbited the Earth 256 times, traveled over 6 million miles, and logged a total of 15 days, 21 hours, 52 minutes and 21 seconds in space.
