STS 125 first space walk EVA #1 - 14 May 2009
Mission specialists John Grunsfeld and Drew Feustel completed STS-125s first spacewalk Thursday at 4:12 p.m. EDT.
During the 7-hour, 20-minute excursion, the pair removed the Wide Field Planetary Camera 2 and replaced it with a new wide-field camera. The new camera will allow the telescope to take large-scale, clear and detailed photos over a wide range of colors.
