September 18, 1954, marks the birth of Takao Doi in Tokyo, Japan. An aerospace engineer and career astronaut, he became the first individual from his nation to perform a spacewalk. His professional trajectory spans multiple decades of involvement in Japanese and international space programs, bridging academic research with practical applications in orbital environments.
Academic Foundation and Early Research
Doi earned his initial doctorate in aerospace engineering from the University of Tokyo in 1983. His early technical focus included propulsion systems and microgravity technology. He conducted research at the Institute of Space and Astronautical Science and served at NASA's Lewis Research Center, alongside studies at the University of Colorado. Later, he obtained a second Ph.D. in Astronomy from Rice University in 2004.

Selected as an astronaut candidate by the National Space Development Agency in 1985, Doi participated in two NASA Space Shuttle missions. In 1997, he flew as a mission specialist aboard STS-87, where he executed the inaugural Japanese spacewalk. He returned to orbit in March 2008 on the STS-123 mission to the International Space Station. During this flight, he assisted in the delivery of the first Kibō module and the Dextre robotic system. He also demonstrated the use of a specially designed boomerang in microgravity.
Astronomy and Post-Flight Career
Beyond his duties as an astronaut, Doi maintains an active profile in observational astronomy, credited with the discovery of supernovae SN 2002gw and SN 2007aa. Following his retirement from active astronaut status in September 2009, he transitioned to the United Nations Office for Outer Space Affairs, heading the Space Applications Section. He later shifted toward academia, joining Kyoto University as a professor in the Unit of Synergetic Studies for Space in 2016, and subsequently the Graduate School of Advanced Integrated Studies in Human Survivability in 2020.
