Early life

Chiao was born in Milwaukee, Wisconsin and raised in Danville, California.[2] Chiao graduated from Monte Vista High School in Danville in 1978. In 1983, he received a Bachelor of Science in chemical engineering from the University of California, Berkeley, where he became a member of the Phi Kappa Tau fraternity. He earned a Master of Science and then a Doctor of Philosophy in chemical engineering from the University of California, Santa Barbara in 1985 and 1987, respectively.[2]

Chiao’s father (Tsu Tao Chiao) grew up in Shandong, China; his mother, Dr. Cherry Chiao, was born in Qingdao, Shandong and grew up in Suzhou. After World War II, they both fled to Taiwan, where they met and married. His parents immigrated to the United States in the 1950s. Chiao's call sign is "Shandong".[4]

Pre-NASA career

Upon graduation, Chiao worked at Hexcel Corporation in Dublin, California from 1987 to 1989.[2] He was involved in process, manufacturing and engineering research on advanced aerospace materials, and 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.[2] In January 1989, 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. Chiao also developed and demonstrated a mechanistic cure model for graphite fiber/epoxy composite material (see Graphite-reinforced plastic). An instrument-rated pilot, Chiao has logged over 2500 flight hours in a variety of aircraft.[2]

NASA career

Selected by NASA in January 1990, Chiao became an astronaut in July 1991. He is qualified for flight assignment as a mission specialist. 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; and Extra-vehicular activity (EVA) issues for the EVA Branch. Chiao also served as Chief of the Astronaut Office EVA Branch.[2]

A veteran of four space flights, Chiao flew as a mission specialist on STS-65 in 1994, STS-72 in 1996 and STS-92 in 2000. Chiao had logged over 36 days and 12.5 hours in space, including over 26 EVA hours in four space walks, prior to his mission aboard the International Space Station.[2]

In addition to being fluent in Mandarin, Chiao learned Russian as part of the International Space Station program. On November 2, 2004, Chiao voted in the 2004 United States presidential election from aboard the International Space Station, making him the first American to vote in a presidential election while in space.[5] McDonald’s presented Chiao with a Big Mac and French Fries at their branch in Star City as one of his first meals since returning to Earth after his ISS assignment.[6] Among the souvenirs he brought into space in his previous space flights were a Chinese flag and a quartz-carved rose from Hong Kong.

Chiao was the inadvertent developer of the procedure to use the IRED (Interim Resistive Exercise Device) to excite the solar arrays of the ISS. During an exercise session of squats on the ISS, Chiao sent a vibration through the space station that caused the solar arrays to ripple – a low amplitude frequency response. When Chiao did this, the response from Mission Control was "knock it off." However, several years later during an ISS assembly flight in December 2006 (STS-116), German astronaut Thomas Reiter of the European Space Agency was told to do 30 seconds of robust exercise on the bungee-bar IRED machine to help retract ISS solar arrays, specifically to relieve tension in a wire system that was preventing the array from folding up like an accordion. An eventual unplanned spacewalk during the same shuttle mission managed to finally retract the array.

Chiao left NASA in December 2005 to pursue employment in the private sector.[7]

Spaceflight experience

President George W. Bush welcomed the crew members and families of the International Space Station expeditions 7, 8, 9 and 10 to the Oval Office in May 2005. From left: Lt. Colonel Mike Fincke, ISS 9; Dr. Edward Lu, ISS 7; Dr. Leroy Chiao, ISS 10, and Dr. Michael Foale, ISS 8.

STS-65 Columbia (July 8 – July 23, 1994) launched from and returned to land at the Kennedy Space Center, Florida, 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 seven-member crew conducted more than 80 experiments focusing on materials and life sciences research in microgravity. The STS-65 mission was accomplished in 236 orbits of the Earth, traveling 6.1 million miles in 353 hours and 55 minutes.[2][8]

STS-72 Endeavour (January 11 – January 20, 1996) was a nine-day mission during which the crew retrieved the Space Flyer Unit (launched from Japan ten months earlier), and deployed and retrieved the OAST-Flyer. Chiao performed two spacewalks designed to demonstrate tools and hardware, and evaluate techniques to be used in the assembly of the International Space Station. In completing this mission, Chiao logged a total of 214 hours and 41 seconds in space, including just over thirteen EVA hours, and traveled 3.7 million miles in 142 orbits of the Earth.[2][9]

STS-92 Discovery (October 11 – October 24, 2000) was launched from the Kennedy Space Center, Florida and returned to land at Edwards Air Force Base, California. During the 13-day flight, the seven member crew attached the Z1 Truss and Pressurized Mating Adapter 3 to the International Space Station using Discovery’s robotic arm and performed four space walks to configure these elements. This expansion of the ISS opened the door for future assembly missions and prepared the station for its first resident crew. Chiao totaled 13 hours and 16 minutes of EVA time in two space walks. The STS-92 mission was accomplished in 202 orbits, traveling 5.3 million miles in 12 days, 21 hours, 40 minutes and 25 seconds.[2][10]

ISS Expedition 10 (October 9, 2004 – April 24, 2005), Chiao was the Commander of Expedition 10 on the International Space Station.[2][11]

Post-NASA career

After leaving NASA, Chiao has become involved in entrepreneurial business ventures in both the U.S. and China.[12]

In early 2006, he joined the Atlanta firm of SpaceWorks Enterprises, Inc. (SEI) as an affiliate and technical advisor (on a non-exclusive basis). Dr. Chiao assists the firm on space technologies and operating processes for future space exploration concepts and research on the commercialization of space.[13] In July 2006, Chiao accepted a position as the Executive Vice President for Space Operations and a Director of Excalibur Almaz Limited.[12] He was responsible for operational aspects of spaceflight, including training for both the capsule and space station.[12] The company assembled a team from the Isle of Man, the United States, Russia, the Ukraine, and Continental Europe to begin work towards refurbishing and flying a capsule in space based upon the design of the Almaz capsules.

In March 2006, Chiao began an appointment in the Mechanical Engineering Department at the Louisiana State University as the first Raborn Distinguished Chair Max Faget Professor.[14]

Chiao is also currently serving as the Chairman of the National Space Biomedical Research Institute (NSBRI) User Panel, which is attached to the Baylor College of Medicine.[15] The NSBRI, funded by NASA, is a consortium of institutions studying the health risks related to long-duration space flight. The Institute’s User Panel is an advisory board composed of former and current astronauts and flight surgeons that ensures NSBRI’s research program is focused on astronaut health and safety. In preparation for lunar and Mars exploration, Chiao and the User Panel will help align NSBRI’s science and technology projects with the needs of astronauts on long missions.[15]

In July 2007, Chiao joined an expedition to visit Devon Island and conduct 5 days of webcasts and other instructional activities spanning the period of 16–20 July 2007.[16] This activity was sponsored by the Mars Institute and the Challenger Center for Space Science Education with additional assistance from The Explorers Club and SpaceRef Interactive, Inc. He conducted these webcasts from the Haughton-Mars Project Research Station and nearby locations to illustrate how NASA and other space agencies are learning to live on the Moon and Mars here on Earth.[16]

Chiao appeared in an episode of MANswers in 2008 explaining how to neutralize an astronaut in space who has gone berserk. [2]

In May 2009 Chiao wrote a few blog articles on detailing some of his space experiences.

In May 2009 Chiao was named as a member of the Review of United States Human Space Flight Plans Committee an independent review requested by the Office of Science and Technology Policy (OSTP) on May 7, 2009.

In a special to CNN written by Chiao on 1 September 2011, he suggested that China be permitted to join the International Space Station program to remedy the issue relating to the limited options available for space travel, following the conclusion of the United States space shuttle program, and a failure of a Russian Soyuz spacecraft on 24 August 2011.[17]

In December 2011 Chiao joined Epiphan Systems as VP Aerospace. Based on NASA's space technologies, Epiphan Systems produces high resolution video capture, streaming, and recording products for the medical, educational, IT, and industrial markets.[18] Chiao's role at Epiphan Systems is to work with the aerospace industry to define the company's vision and achieve strategic goals in areas such as air traffic control.[19]

In 2012, Chiao was named special advisor – human spaceflight for the Space Foundation.

Personal life

Chiao married Karen Chiao in 2003. He enjoys flying his Grumman Tiger aircraft, as well as downhill skiing. He speaks English, Mandarin Chinese and Russian.[2][20]
