Hoffman made five flights as a space shuttle astronaut, including the first mission to repair the Hubble Space Telescope in 1993, when the orbiting telescope's flawed optical system was corrected. Trained as an astrophysicist, he also flew on 1990 Spacelab shuttle mission that featured the ASTRO-1 ultraviolet astronomical observatory in the shuttle's payload bay.
