Tethered to the end of the remote manipulator system arm, which was controlled from inside Atlantis' crew cabin, STS-125 astronaut Andrew Feustel navigates near the Hubble Space Telescope, duing the mission's third spacewalk on May 16, 2009. Astronaut John Grunsfeld signals to his crewmate from just a few feet away. Astronauts Feustel and Grunsfeld were continuing servicing work on the giant observatory, which was locked down in the cargo bay of shuttle Atlantis.
