Astronaut John Grunsfeld, STS-125 mission specialist, positioned on a foot restraint on the end of Atlantis' remote manipulator system (RMS), participates in the mission's fifth and final session of extravehicular activity (EVA) as work continues to refurbish and upgrade the Hubble Space Telescope. During the seven-hour and two-minute spacewalk, Grunsfeld and astronaut Andrew Feustel (out of frame), mission specialist, installed a battery group replacement, removed and replaced a Fine Guidance Sensor and three thermal blankets (NOBL) protecting Hubble's electronics. The blackness of space and the thin line of Earth's atmosphere provide the backdrop for this scene.
