NASA Official Biography

NAME: Donald A. Thomas (Ph.D.)
NASA Astronaut

PERSONAL DATA:
Born May 6, 1955, in Cleveland, Ohio. Married to the former Simone Lehmann of G�ppingen, Germany. They have one son. He enjoys swimming, biking, camping, flying. His mother, Mrs. Irene M. Thomas, resides in Bloomington, Indiana. Her parents, Margrit and Gerhard Lehmann, reside in G�ppingen, Germany.

EDUCATION:
Graduated from Cleveland Heights High School, Cleveland Heights, Ohio, in 1973; received a bachelor of science degree in Physics from Case Western Reserve University in 1977, and a master of science degree and a doctorate in Materials Science from Cornell University in 1980 and 1982, respectively. His dissertation involved evaluating the effect of crystalline defects and sample purity on the superconducting properties of niobium.

ORGANIZATIONS:
Member, American Institute of Aeronautics and Astronautics (AIAA), Tau Beta Pi, and Association of Space Explorers (ASE).

SPECIAL HONORS:
Graduated with Honors from Case Western Reserve University in 1977. Recipient of NASA Sustained Superior Performance Award, 1989. Recipient of NASA Group Achievement Awards in 1990, 1992, and 1994 for his work on the Microgravity Disturbances Experiment, the Shuttle System Safety Review Panel, and development of the Microgravity Measurement Device.

EXPERIENCE:
Following graduation from Cornell University in 1982, Dr. Thomas joined AT&T Bell Laboratories in Princeton, New Jersey, working as a Senior Member of the Technical Staff. His responsibilities there included the development of advanced materials and processes for high density interconnections of semiconductor devices. He was also an adjunct professor in the Physics Department at Trenton State College in New Jersey. He holds two patents and has authored several technical papers. He left AT&T in 1987 to work for Lockheed Engineering and Sciences Company in Houston, Texas, where his responsibilities involved reviewing materials used in Space Shuttle payloads. In 1988 he joined NASA's Lyndon B. Johnson Space Center as a Materials Engineer. His work involved lifetime projections of advanced composite materials for use on Space Station Freedom. He was also a Principal Investigator for the Microgravity Disturbances Experiment, a middeck crystal growth experiment which flew on STS-32 in January 1990. This experiment investigated the effects of Orbiter and crew-induced disturbances on the growth of crystals in space.

He is a private pilot with over 250 hours in single engine land aircraft and gliders, and over 600 hours flying as mission specialist in NASA T-38 jet aircraft.

Selected by NASA in January 1990, Dr. Thomas became an astronaut in July 1991. He has worked in the Safety and Operations Development Branches of the Astronaut Office working on issues relating to Shuttle Orbiter systems, and was also a spacecraft communicator (CAPCOM) for Shuttle missions STS-47, 52 and 53. A veteran of three space flights, he has logged 663 hours and 27 minutes in space. He was a mission specialist on STS-65 (July 8-23, 1994), STS-70 (July 13-22, 1995) and STS-83 (April 4-8, 1997). He is scheduled to fly aboard Columbia on STS-94 in the Summer of 1997.

STS-65 flew the second International Microgravity Laboratory (IML-2) Spacelab module. The seven-member crew aboard Space Shuttle Columbia launched from Kennedy Space Center in Florida on July 8, 1994, and returned there on July 23, 1994 setting a new flight duration record for the Space Shuttle program. During the 15-day flight the crew conducted more than 80 experiments focusing on materials and life sciences research in microgravity. The mission was accomplished in 236 orbits of the Earth, traveling 6.1 million miles.

On STS-70, Dr. Thomas was responsible for the deployment of the sixth and final Tracking and Data Relay Satellite from the Space Shuttle. The five-member crew aboard Space Shuttle Discovery launched from the Kennedy Space Center July 13, 1995, and returned there July 22, 1995. During the 8 day 22 hour mission, the crew completed 142 orbits of the Earth, traveling 3.7 million miles.

STS-83, the Microgravity Science Laboratory (MSL-1) Spacelab mission, was cut short because of problems with one of the Shuttle's three fuel cell power generation units. Mission duration was 95 hours and 12 minutes, traveling 1.5 million miles in 63 orbits of the Earth.

CURRENT ASSIGNMENT:
Dr. Thomas will serve as a mission specialist on STS-94. The 16-day re-flight of the Microgravity Science Laboratory (MSL-1) Spacelab mission will focus on materials and combustion science research in microgravity. Launch is scheduled for the Summer of 1997 aboard Space Shuttle Columbia.
