In March 2002, a team of seven astronauts launched from the KennedyCenter aboard Space Shuttle Columbia in route to the Hubble SpaceTelescope. The Hubble Space Telescope was designed to be servicedperiodically to upgrade its instruments and fix broken equipment. TheSTS-109 mission, the fourth Hubble servicing mission, was the mostambitious 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 cameraback to life. Details of the mission will be presented, as well assome of the first exciting pictures from the new camera.John Mace Grunsfeld received a B.S. degree in physics fromM.I.T. ; an M.S. degree and Ph.D. in physics from the University ofChicago. Dr. Grunsfeld studies binary pulsars and energetic x-ray andgamma ray sources using the NASA Compton Gamma Ray Observatory, x-rayastronomy satellites, radio telescopes, and optical telescopesincluding the NASA Hubble Space Telescope. He became an astronaut in1992 and led a team of scientists tasked with defining and producingthe crew displays for command and control of the International SpaceCenter (ISS). He has logged over 45 days in space, including 5 spacewalks. He participated in the second flight of the astro observatoryin 1995. He served as flight engineer of a 10 day mission to dockwith Russia's Space Station Mir in 1997. He has participated in twoservicing missions of the Hubble Telescope in 1999 and 2002.
