the Astronaut Office Payload Safety Representative. He has also worked on EVA, including the
development of a high-pressure spacesuit for use on the Space Station. Dr. Hoffman is a member of the

Dr. Hoffman made his first space flight as a mission specialist on STS 51-D, April 12-19, 1985, on the
Shuttle Discovery. On this mission, he made the first STS contingency space walk, in an attempted rescue
of a malfunctioning satellite.
Dr. Hoffman made his second space flight as a mission specialist on STS-35, December 2-10, 1990, on the
Shuttle Columbia. This Spacelab mission featured the ASTRO-1 ultraviolet astronomy laboratory, a project
on which Dr. Hoffman had worked since 1982.
Dr. Hoffman made his third space flight as payload commander and mission specialist on STS-46, July 31-
August 8, 1992, on the Shuttle Atlantis. On this mission, the crew deployed the European Retrievable
Carrier (EURECA), an ESA- sponsored free-flying science platform, and carried out the first test flight of
the Tethered Satellite System (TSS), a joint project between NASA and the Italian Space Agency. Dr.
Hoffman had worked on the Tethered Satellite project since 1987.
Dr. Hoffman made his fourth flight as an EVA crew member on STS-61, December 2-13, 1993, on the
Shuttle Endeavour. During this flight, the Hubble Space Telescope (HST) was captured, serviced, and
restored to full capacity through a record five space walks by four astronauts.
With the completion of his fourth space flight, Dr. Hoffman has logged more than 834 hours and 15
million miles in space.
