STS-109 MS Linnehan in payload bay on third EVA

STS109-E-5379 (6 March 2002) --- Astronaut Richard M. Linnehan, mission specialist, works on the Hubble Space Telescope (HST) in the cargo bay of the Space Shuttle Columbia during the STS-109 mission's third space walk. The primary purpose of the extravehicular activity (EVA) of astronauts Linnehan and John M. Grunsfeld was to replace the Power Control Unit on the giant telescope. The image was recorded with a digital still camera by one of Linnehan's crew mates inside Columbia's crew cabin.
