During the 1993 STS-61 mission, Jeffrey A. Hoffman participated in the landmark endeavor to repair the Hubble Space Telescope. By completing a record-breaking series of spacewalks, he helped correct the observatory's flawed optical system, an achievement that restored its capacity to capture data from the universe. This mission marked one of five space flights for the career astronaut.
Early Life and Academic Foundation
Born in Brooklyn in 1944 and raised in Scarsdale, New York, Hoffman established an extensive academic background. He graduated from Scarsdale High School in 1962 before earning a Bachelor of Arts in astronomy from Amherst College in 1966. He subsequently completed a Doctor of Philosophy in astrophysics at Harvard University in 1971 and added a Master of Science in materials science from Rice University in 1988.

Before joining NASA, Hoffman focused on high-energy astrophysics. During a post-doctoral tenure at the University of Leicester between 1972 and 1975, he contributed to x-ray astronomy rocket payloads and the EXOSAT satellite project. At the Massachusetts Institute of Technology, he served as a project scientist for the HEAO-1 A4 experiment, studying cosmic x-ray bursts through data analysis and instrumentation design.
Spaceflight and EVA Operations
Selected by NASA in 1978 and becoming an astronaut in 1979, Hoffman logged over 1,211 hours and 21.5 million miles across five shuttle missions. His flights included STS 51-D, where he performed the first contingency spacewalk, and STS-35, which utilized the Astro-1 observatory. He served as payload commander for STS-46 and participated in the orbital repair of the Hubble Space Telescope during STS-61.
Academic Tenure and NASA Representation
After leaving the astronaut program in 1997, Hoffman served as NASA’s European Representative in Paris until 2001. He later transitioned to the Massachusetts Institute of Technology, where he serves as a professor of the Practice in the Department of Aeronautics and Astronautics. His current academic work addresses human space flight operations, systems design, and human-machine interaction.
