Astronaut John Grunsfeld, positioned on a foot restraint on the end of Atlantis' remote manipulator system, participated in the mission's fifth and final spacewalk as work continued to refurbish and upgrade the Hubble Space Telescope. During the seven-hour spacewalk, Grunsfeld and astronaut Andrew Feustel (out of frame) installed a battery group replacement, removed and replaced a fine guidance sensor and three thermal blankets that protect Hubble's electronics.
