STS-109 MS Newman and Massimino during EVA 4

Dark view of two of Columbia's four spacewalkers--astronauts James H. Newman and Michael J. Massimino--participating in the first science instrument upgrade of the fourth Hubble Space Telescope HST servicing mission during the flight's fourth day of extravehicular activity EVA. The two, with Newman on Columbia's remote manipulator system RMS robotic arm, remove the Faint Object Camera to make room for the new Advanced Camera for Surveys ACS.
