Astronaut Space Shuttle Missions

Astronauts John M. Grunsfeld (right) and Richard M. Linnehan, STS-109 payload commander and mission specialist, respectively, are photographed near the Hubble Space Telescope (HST) temporarily parked in the Space Shuttle Columbia’s cargo bay at the close of the fifth and final day of extravehicular activities (EVAs). Their spacewalk centered around the Near-Infrared Camera and Multi-Object Spectrometer (NICMOS), to install a Cryogenic Cooler and its Cooling System Radiator.
