As a NASA astronaut (1978-1997), Jeffrey Hoffman made five space flights, becoming the first astronaut to log 1000 hours of flight time aboard the Space Shuttle. Dr. Hoffman was Payload Commander of STS-46, the first flight of the US-Italian Tethered Satellite System. He has performed four spacewalks, including the first unplanned, contingency spacewalk in NASA’s history (STS-51D; April 1985) and the initial repair/rescue mission for the Hubble Space Telescope (STS-61; December 1993). As the Astronaut Office representative for Extravehicular Activity, he helped develop and carry out tests of advanced high-pressure space suit designs and of new tools and procedures needed for the assembly of the International Space Station. Following his astronaut career, Dr. Hoffman spent four years as NASA’s European Representative, working at the US Embassy in Paris.
In August 2001, Dr. Hoffman joined the MIT faculty, where he teaches courses on space operations and space systems design. His primary research interests are in improving the technology of space suits and designing innovative space systems for human and robotic space exploration. He is Deputy Principal Investigator of an experiment on NASA’s Mars 2020 mission, which will for the first time produce oxygen from extraterrestrial material, a critical step in the future of human space exploration.
