STS109-E-5668 (6 March 2002) --- The two space walking teams of STS-109 crew members, who today surpassed the halfway point in their extravehicular activity (EVA) duty, pose for a snapshot on the mid deck of the Space Shuttle Columbia. From the left are astronauts Richard M. Linnehan, James H. Newman, John M. Grunsfeld and Michael J. Massimino. Following the second spacewalk by the Grunsfeld-Linnehan duo earlier today, marking the third overall for the STS-109 mission, each team has one space walk remaining. The image was recorded with a digital still camera.
