Two of Columbia's four spacewalkers--astronauts James H. Newman and Michael J. Massimino--participate 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, removed the Faint Object Camera to make room for the new Advanced Camera for Surveys (ACS). The HST, illuminated by the sunrise, provides stark contrast to the blackness of space in this scene. Arching between the telescope and one of the solar panels is the thin line of Earth’s atmosphere.
