Hubble Space Telescope (HST)

A STS-125 crew member aboard the Space Shuttle Atlantis captured this still image of the Hubble Space Telescope as the two spacecraft continued their relative separation on May 19, 2009, after being linked together for the better part of a week. During the week, five spacewalks were performed to complete the final servicing mission for the orbital observatory.
