Astronaut Mike Fincke successfully released three bolts on a spare arm for Dextre, the Canadian Special Purpose Dexterous Manipulator. He did make use of a specially designed pry rod.
Meanwhile, Greg Chamitoff recharged his oxygen then tightened a loose tether on Dextre.
The spacewalkers then traversed to the ExPRESS Logistics Carrier #3 to take some photos of an experiment on that platform. The Space Test Program-Houston 3 payload, is a complement of four individual experiments that will test concepts in low-Earth orbit for long duration.
They now will clean up work areas and head back to the Quest airlock to conclude the final spacewalk made by space shuttle astronauts.
