Perched on the end of the Canadian-built Remote Manipulator System, astronaut Andrew Feustel, mission specialist, performs work on the Hubble Space Telescope during the first of five STS-125 spacewalks, kicking off a week's work on the orbiting observatory. Feustel, teamed with astronaut John Grunsfeld (out of frame), joined the veteran spacewalker on two of the four remaining sessions of extravehicular activity later in the mission.
