The third of five STS-125 spacewalks concluded at 4:11 p.m. ET. It was 6 hours, 36 minutes. During the endeavour outside the Shuttle, Feustel and Grunsfeld removed the Corrective Optics Space Telescope Axial Replacement and installed in its place the new Cosmic Origins Spectrograph. They also completed the Advanced Camera for Surveys electronic card replacement work. The spacewalkers were ahead of schedule and were able to complete part 2 of the ACS repair, installing a new electronics box and cable.

The participants will be Tony Ceccacci, STS-125 lead flight director, Tomas Gonzalez-Torres, STS-125 lead EVA officer, Jon Morse, director, Astrophysics Division, Preston Burch, HST Program manager, and Dave Leckrone, HST Senior Scientist.
