With the Space Shuttle Columbia in limited natural light, two astronauts work on the Hubble Space Telescope (HST) during the flight's second of five space walks. A thin slice of reflected sunlight and airglow can be seen at Earth's horizon. Mission specialists Michael J. Massimino (on the platform at the end of the robotic arm) and James H. Newman (out of frame) are making their first extravehicular activity (EVA) of the mission.
