NASA Official Biography

NAME: Leroy Chiao (Ph.D.)
NASA Astronaut

Born August 28, 1960, in Milwaukee, Wisconsin, but considers Danville, California, to be his hometown. Single. He enjoys flying, basketball, racquetball, and skiing. His parents, Mr. & Mrs. Tsu Tao Chiao, reside in Fairfield, California.

Graduated from Monte Vista High School, Danville, California, in 1978; received a bachelor of science degree in chemical engineering from the University of California, Berkeley, in 1983, and a master of science degree and a doctorate in chemical engineering from the University of California, Santa Barbara, in 1985 and 1987, respectively.

Member of the American Institute of Aeronautics and Astronautics (AIAA), the American Society for Testing and Materials (ASTM), and the Society for the Advancement of Material and Process Engineering (SAMPE).

Invited to give technical seminars on honeycomb material and bonded panels, and cure modeling of aerospace composite materials, at the Beijing Institute of Aeronautical Materials, and at the Changsha Institute of Technology, 5th Department, in the Peoples Republic of China. Invited contributor to the International Encyclopedia of Composite Materials. Listed in Who's Who in Science and Engineering. Recipient of Distinguished Alumni Award from University of California, Santa Barbara.

Dr. Chiao graduated in 1987 from the University of California at Santa Barbara, and joined the Hexcel Corporation in Dublin, California. He worked for Hexcel until 1989, during which time he was involved in process, manufacturing, and engineering research on advanced aerospace materials; worked on a joint NASA-JPL/Hexcel project to develop a practical, optically correct, precision segment reflector, made entirely of advanced polymer composite materials, for future space telescopes; as well as working on cure modeling and finite element analysis. In January of 1989 Dr. Chiao joined the Lawrence Livermore National Laboratory in Livermore, California, where he was involved in processing research for fabrication of filament-wound and thick-section aerospace composites. Dr. Chiao also developed and demonstrated a mechanistic cure model for graphite fiber/epoxy composite material. An instrument-rated pilot, Dr. Chiao has logged over 1500 flight hours in a variety of aircraft.

Selected by NASA in January 1990, Dr. Chiao became an astronaut in July 1991. He is qualified for assignment as a mission specialist on future Space Shuttle flight crews. His technical assignments to date include: Space Shuttle flight software verification in the Shuttle Avionics Integration Laboratory (SAIL); crew equipment, Spacelab, Spacehab and payloads issues for the Astronaut Office Mission Development Branch; Training and Flight Data File issues. A veteran of two space flights, he flew as a mission specialist on STS-65 in 1994 and STS-72 in 1996. Dr. Chiao has logged 567 hours, 55 minutes, 41 seconds in space, including two spacewalks totaling just over 13 hours.

On STS-65, his first flight, 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 at that time. The STS-65 mission flew the second International Microgravity Laboratory (IML-2). 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 in 353 hours and 55 minutes.

Most recently, Dr. Chiao flew on STS-72 (January 11-20, 1996). During the 9-day flight the crew aboard Endeavour retrieved the Space Flyer Unit (launched from Japan 10-months earlier), and deployed and retrieved the OAST-Flyer. Dr. Chiao performed two spacewalks designed to demonstrate and evaluate techniques to be used in the assembly of the International Space Station. In completing his second space flight, Dr. Chiao orbited the Earth 142 times, traveled 3.7 million miles, and logged a total of 214 hours and 41 seconds in space, including just over 13 EVA hours.
