[edit] Science career
Grunsfeld’s academic positions include that of Visiting Scientist, University of Tokyo/Institute of Space and Astronautical Science (1980-81); Graduate Research Assistant, University of Chicago (1981-85); NASA Graduate Student Fellow, University of Chicago (1985-87); W.D. Grainger Postdoctoral Fellow in Experimental Physics, University of Chicago (1988-89); and Senior Research Fellow, California Institute of Technology (1989-92). Grunsfeld’s research has covered x-ray and gamma-ray astronomy, high-energy cosmic ray studies, and development of new detectors and instrumentation. Grunsfeld studied binary pulsars and energetic x-ray and gamma ray sources using the NASA Compton Gamma Ray Observatory, x-ray astronomy satellites, radio telescopes, and optical telescopes including the NASA Hubble Space Telescope.
[edit] NASA career
Grunsfeld was selected by NASA in March 1992 as an astronaut candidate and reported to the Johnson Space Center in August 1992. He completed one year of training and qualified for flight selection as a mission specialist. Grunsfeld was initially detailed to the Astronaut Office Mission Development Branch and was assigned as the lead for portable computers for use in space. Following his first flight, he led a team of engineers and computer programmers tasked with defining and producing the crew displays for command and control of the International Space Station (ISS). As part of this activity he directed an effort combining the resources of the Mission Control Center (MCC) Display Team and the Space Station Training Facility. The result was the creation of the Common Display Development Facility (CDDF), responsible for the onboard and MCC displays for the International Space Station, using object-oriented programming techniques. Following his second flight, he was assigned as Chief of the Computer Support Branch in the Astronaut Office supporting Space Shuttle and International Space Station Programs and advanced technology development. Following STS-103, he served as Chief of the Extravehicular Activity Branch in the Astronaut Office. Following STS-109, Grunsfeld served as an instructor in the Extravehicular Activity Branch, and worked on the Orbital Space Plane, exploration concepts, and technologies for use beyond low earth orbit in the Advanced Programs Branch. He is currently the NASA Chief Scientist and assigned to NASA Headquarters.
[edit] Spaceflight experience
STS-67/Astro-2 Endeavour (March 2-18,1995) was launched from Kennedy Space Center, Florida, and returned to land at Edwards Air Force Base, California. It was the second flight of the Astro observatory, a unique complement of three ultra-violet telescopes. During this record-setting 16-day mission, the crew conducted observations around the clock to study the far ultraviolet spectra of faint astronomical objects and the polarization of ultraviolet light coming from hot stars and distant galaxies. Mission duration was 399 hours and 9 minutes.
STS-81 Atlantis (January 12-22, 1997) was a 10-day mission, the fifth to dock with Russia’s Mir space station, and the second to exchange U.S. astronauts. The mission also carried the Spacehab double module providing additional middeck locker space for secondary experiments. In five days of docked operations more than three tons of food, water, experiment equipment and samples were moved back and forth between the two spacecraft. Grunsfeld served as the flight engineer on this flight. Following 160 orbits of the Earth the STS-81 mission concluded with a landing on Kennedy Space Center’s Runway 33 ending a 3.9 million mile journey. Mission duration was 244 hours, 56 minutes. During this flight, Grunsfeld placed a phonecall to NPR's auto-repair radio show, Car Talk.
STS-103 Discovery (December 19-27, 1999) was an eight-day mission during which the crew successfully installed new gyroscopes and scientific instruments and upgraded systems on the Hubble Space Telescope (HST). Enhancing HST scientific capabilities required three space walks (EVA). Grunsfeld performed two space walks totaling 16 hours and 23 minutes. The STS-103 mission was accomplished in 120 Earth orbits, traveling 3.2 million miles in 191 hours and 11 minutes.
STS-109 Columbia (March 1-12, 2002) was the fourth Hubble Space Telescope (HST) servicing mission. The crew of STS-109 successfully upgraded the Hubble Space Telescope installing a new digital camera, a cooling system for the infrared camera, new solar arrays and a new power system. HST servicing and upgrades were accomplished by four crewmembers during a total of five EVAs in five consecutive days. Grunsfeld served as the Payload Commander on STS-109 in charge of the space walking activities and the Hubble payload. He also performed three space walks totaling 21 hours and 9 minutes, including the installation of the new Power Control Unit. STS-109 orbited the Earth 165 times, and covered 3.9 million miles in over 262 hours.
He is scheduled to fly on STS-125, the final Hubble servicing mission by the Space Shuttle.
