STS109-E-5557 (8 March 2002) --- Astronauts John M. Grunsfeld (left), payload commander, and Richard M. Linnehan, mission specialist, anchored to a restraint on Columbia's robotic arm, participate in the final of five
STS-109 space walks. The two went on to install an experimental cooling system for the Hubble Space Telescope�s infrared Camera and Multi-Object Spectrometer (NICMOS). This image was recorded with a digital still camera by a crewmate inside the shuttle's crew cabin. The NICMOS has been dormant since January 1999 when its original coolant ran out.
