New Eyes for Space Exploration: Upgrading the Hubble Space Telescope
Dr. John Grunsfeld, NASA Astronaut
In March 2002, a team of seven astronauts launched from the Kennedy
Center aboard Space Shuttle Columbia in route to the Hubble Space
Telescope. The Hubble Space Telescope was designed to be serviced
periodically to upgrade its instruments and fix broken equipment. The
STS-109 mission, the fourth Hubble servicing mission, was the most
ambitious repair mission to date. Over a series of five space walks,
astronauts in space suits replaced the solar arrays and power system,
installed a new sensitive camera, and brought an infra-red camera
back to life. Details of the mission will be presented, as well as
some of the first exciting pictures from the new camera.
||John Mace Grunsfeld received a B.S. degree in physics from
M.I.T. ; an M.S. degree and Ph.D. in physics from the University of
Chicago. Dr. Grunsfeld studies 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. He became an astronaut in
1992 and led a team of scientists tasked with defining and producing
the crew displays for command and control of the International Space
Center (ISS). He has logged over 45 days in space, including 5 space
walks. He participated in the second flight of the astro observatory
in 1995. He served as flight engineer of a 10 day mission to dock
with Russia's Space Station Mir in 1997. He has participated in two
servicing missions of the Hubble Telescope in 1999 and 2002.
