Jeffrey Alan Hoffman ( born November 2, 1944 in Brooklyn, New York State, United States) is a former American astronaut.
Training
Hoffman received a BA in astronomy in 1966 from Amherst College in 1971 and a doctorate in astrophysics from Harvard University. In 1988 he received a Masters degree in materials science from Rice University.
From 1972 to 1975 Hoffman worked at the University of Leicester in the UK in the development of various space X-ray telescopes and other experiments for X-rays. He also worked on an X-ray experiment for the satellite EXOSAT ESA.
From 1975 to 1978 he worked as a project scientist at the Space Research Centre at the Massachusetts Institute of Technology (MIT).
Astronauts activity
In January 1978, Hoffman was selected by NASA as an astronaut candidate. During the preparations for the first shuttle flights worked at the Flight Simulation Laboratory in Downey, California. He was a member of the support team for the Space Shuttle mission STS -5 and worked as a speaker connection ( CAPCOM ) for the Missions STS- 8 and STS- 82nd He was representative of the Astronaut Office for payload safety. He worked in the development of a space suit for spacewalks and in the preparations for the construction of the International Space Station ( ISS). He became head of the Payload and Habitability of the Astronaut Office 1996.
STS -41 -F
STS -41 -F was scheduled for August 1984 with the discovery. This would have been the first flight of Discovery, if it had not been canceled due to delays in payload. As the occupying Karol Bobko, Donald Williams, Rhea Seddon, David Griggs and Jeffrey Hoffman were provided. The flight was STS -51 -E.
STS -51- E
This flight of the Challenger was canceled due to problems of the IUS upper stage. It should have been exposed to a TDRS satellite. As the occupying Karol Bobko, Donald Williams, Rhea Seddon, David Griggs, Jeffrey Hoffman, the French payload specialist Patrick Baudry and politicians Jake Garn were provided.
STS -51- D
On April 12, 1985 Hoffman started as a mission specialist aboard the space shuttle Discovery for the first time into space. Payload were the two satellites TELESAT -9 and LEASAT - third In the latter, however, the automatic startup of the antenna and the engine did not work. In a spacewalk Hoffman was with his fellow astronaut David Griggs not fix this defect.
STS -61- E
This mission aboard the space shuttle Columbia had in March 1986, the ASTRO -1 Spacelab mission are to bring into space. After the Challenger disaster the flight was canceled. The team would have consisted of Jon McBride, Richard Richards, David Leestma, Jeffrey Hoffman, Robert Parker, Samuel Durrance and Ronald Parise.
STS -35
On 2 December 1990 Hoffman started as a mission specialist aboard the space shuttle Columbia into space. During this flight, there were start-up delays, so that the first time in history, two space shuttles faced ready on the launch pads. The main objective of the mission were astronomical observations with the instruments of the ASTRO -1 platform in the UV and X-rays. During the mission, there were some technical problems, so functioned as the display for aligning the ASTRO -1 telescopes not. The telescopes therefore had to be controlled from Earth. However, the scientific objectives could still be achieved at around 70 percent.
STS -46
Hoffman launched on the Space Shuttle Atlantis on 31 July 1992 on mission STS - 46th During the eight-day flight, the satellite EURECA was suspended and carried out trials with the Tethered Satellite System (TSS ).
STS -61
Hoffman flew on 2 December 1993 as a mission specialist aboard the space shuttle Endeavour for the fourth time into space. It was the first repair mission of the Hubble Space Telescope (HST ). The primary mirror of the three and a half years previously started observatory was faulty, resulting in blurred images. Hoffman participated in three of the five extravehicular activities ( EVAs ), which were required to install the correction instrument COSTAR and WF / PC - II camera. Furthermore, the solar panels have been replaced for the power supply for the HST.
STS -75
On 22 February 1996 Hoffman started as a mission specialist aboard the space shuttle Columbia on its last mission into space. Main tasks of the mission were the re- launching of a Tethered Satellite System ( TSS) and experiments with the United States Microgravity Payload ( USMP -3). TSS successfully demonstrated the ability to produce electricity with a tensioned cable. The TSS experiment provided valuable results before the crack over 19 km long extended cable.
According to the NASA
In July 1997, Hoffman resigned from the astronaut program and was the European representative of NASA in Paris. There he was responsible for the coordination of space projects in the U.S. and Europe. From August 2001 he joined as a professor of aerospace to the Massachusetts Institute of Technology (MIT). Since 2005 Hoffman senior staff member of the Massachusetts Space Grant Consortium is in the air and space department at MIT.
Private
Jeffrey Hoffman is married and has two children.
