About Brian O'Leary

Brian Todd O'Leary (January 27, 1940 – July 28, 2011) was an American scientist, author, and former NASA astronaut.

He was part of NASA Astronaut Group 6, a group of scientist-astronauts chosen with the intention of training for the Apollo Applications Program.


O'Leary graduated from Belmont High School in 1957. He received a B.A. in physics from Williams College in 1961, an M.A. in astronomy from Georgetown University in 1964, and a Ph.D. in astronomy from the University of California, Berkeley in 1967.

Academic career

After O'Leary's resignation from NASA, Carl Sagan invited him to lecture at Cornell University in 1968, where he stayed until 1971 as a research associate (1968–1969) and assistant professor (1969–1971) of astronomy. While at Cornell, he studied lunar mascons. During the 1970–1971 academic year, O'Leary was deputy team leader of the Mariner 10 Venus-Mercury TV Science Team as a visiting researcher at the California Institute of Technology. The team received NASA's group achievement award for its participation. He later taught at San Francisco State University (associate professor of astronomy and interdisciplinary sciences; 1971–1972), the UC Berkeley School of Law (visiting associate professor; 1971–1972), Hampshire College (assistant professor of astronomy and science policy assessment; 1972–1975), Princeton University (research staff and lecturer in physics; 1976–1981) and California State University, Long Beach (visiting lecturer in physics; 1986–1987).

At Princeton, he was involved with Gerard K. O'Neill and the L5 Society's orbiting city plans. He suggested that passing asteroids and the moons of Mars would be the easiest to access resources for space colonies.

O'Leary wrote and edited books on astronomy and astronautics.
