Flight Day 7 of the STS-109 mission finds astronaut Richard M. Linnehan, mission specialist, back in the shirt-sleeve environment of the Space Shuttle Columbia. Two of his crewmates were about to begin the fourth space walk of the mission to perform special tasks on the Hubble Space Telescope (HST). Linnehan and John M. Grunsfeld will participate in the fifth and final scheduled spacewalk in a little more than 24 hours. It will mark their third space walk for the mission.
