Franklin Ramón Chang-Díaz (born April 5, 1950)[1] is a Costa Rican American physicist and former NASA astronaut. He is currently president and CEO of Ad Astra Rocket Company.[2] He is a veteran of seven Space Shuttle missions, making him the record holder as of 2008 for the most spaceflights (a record he shares with Jerry L. Ross). He was the third Latin American to go into space,[3] (first Latin American was Arnaldo Tamayo Méndez[4] from Cuba in 1980, and second was Rodolfo Neri Vela from Mexico in 1985) and is the first naturalizedUS citizen to become an astronaut.[5] He is a member of the NASA Astronaut Hall of Fame.

He graduated from Colegio de La Salle in San José in November 1967, then moved to the United States to finish his high school education at Hartford Public High School in Connecticut, in 1969.[11] He went on to attend the University of Connecticut, where he earned a Bachelor of Science in mechanical engineering and joined the federal TRIO Student Support Services program in 1973.[12] He then attended the Massachusetts Institute of Technology, where he earned a Doctor of Plasma Physics in applied plasma physics in 1977.[12] For his graduate research at MIT, Chang-Díaz worked in the field of fusion technology and plasma-based rocket propulsion.[5]
NASA career
NASA career
Chang-Díaz was selected as an astronaut candidate by NASA in 1980 and first flew aboard STS-61-C in 1986. Subsequent missions included STS-34 (1989), STS-46 (1992), STS-60 (1994), STS-75 (1996), STS-91 (1998), and STS-111 (2002). During STS-111, he performed three EVAs with Philippe Perrin as part of the construction of the International Space Station. He was also director of the Advanced Space Propulsion Laboratory at the Johnson Space Center from 1993 to 2005. Chang-Díaz retired from NASA in 2005.[5]
Post-NASA career
Post-NASA career
After leaving NASA, Chang-Díaz set up the Ad Astra Rocket Company, which became dedicated to the development of advanced plasma rocket propulsion technology. Years of research and development have produced the Variable Specific Impulse Magnetoplasma Rocket (VASIMR), an electrical propulsion device for use in space.[13] With a flexible mode of operation, the rocket can achieve very high exhaust speeds, and even has the theoretical capability to take a manned rocket to Mars in 39 days.[14]
Chang-Díaz also is active in environmental protection and raising awareness about climate change, notably in his role in Odyssey 2050 The Movie in which he encourages young people to get motivated about environmental issues.[15]
