It’s the end of an era: the final spacewalk during the space shuttle era was conducted by astronauts on July 12, 2011 during the final shuttle mission, STS-135. This is the 160th spacewalk supporting assembly and maintenance of the space station and the 249th EVA conducted by U.S. astronauts. The two spacwalkers were actually from the International Space Station crew, Expedition 28’s Mike Fossum and Ron Garan, but were assisted by the shuttle crew. Shuttle Pilot Doug Hurley and Mission Specialist Sandy Magnus operated operate the station’s 58-foot-long Canadarm 2 to maneuver the spacewalkers around during the spacewalk.
Here are more images from the EVA:

No, this isn't a picture of an astronaut carrying a freezer outside the space station. With his feet secured on a restraint on the space station remote manipulator system's robotic arm Canadarm2, Mike Fossum holds the Robotics Refueling Mission payload, an experiment which will test in-flight refueling with the DEXTRE robot. Fossum and Ron Garan installed the experiment during the July 12 EVA. Credit: NASA Suspended in a very unique position on the end of Canadarm2, Mike Fossum takes a picture during a July 12 spacewalk.
