STS109-719-008

July 18, 2011
Astronauts Michael J. Massimino, STS-109 mission specialist, anchored on the end of the Space Shuttle Columbia's remote manipulator system (RMS) robotic arm, works in tandem with astronaut James H. Newman, mission specialist, during this second session of extravehicular activity (EVA). Newman and Massimino replaced the second of the Hubble Space Telescopes (HST) new solar arrays and its Diode Box Assembly and replaced the Reaction Wheel Assembly-1. The HST, illuminated by the sunrise, provides stark contrast to the blackness of space and the thin line of Earths atmosphere in this scene.
