Headline: Blurred Vision: Gallery Of Hubble Service Missions Honours 25 Years Since Telescope's 'Eyesight' Was First Fixed

Caption: PICTURE SHOWS: (4 March 2002) Astronaut Richard M. Linnehan, STS-109 mission specialist, anchored on the end of the Space Shuttle Columbia’s Remote Manipulator System (RMS) robotic arm, unfolds a solar array during the mission’s first scheduled session of extravehicular activity (EVA). Astronaut John M. Grunsfeld (out of frame), payload commander, works in tandem with Linnehan during the space walk to replace one of the two Hubble Space Telescope’s (HST) second-generation solar arrays, which is also known as SA2, and a Diode Box Assembly. The solar array was replaced with a new, third-generation solar array, which is called SA3. The space walkers also did some prep work for STS-109’s other sessions of extravehicular activity (EVA).
