Suspended in a unique position on the end of the Space Station Remote Manipulator System, or Canadarm2, NASA astronaut Mike Fossum takes a picture during a July 12 spacewalk.
Fossum and NASA astronaut Ron Garan spent just a little more than six and a half hours on their various tasks.
Fossum, Expedition 28 flight engineer, is shown in one of a series of pictures that documented the July 12 spacewalk.
STS-135 Mission Specialist Sandy Magnus navigates in the weightlessness of space, surrounded by supplies and equipment in the Raffaello multipurpose logistics module.
This view captures a reunion among six NASA astronauts, three Russian cosmonauts and a Japanese astronaut in the International Space Station's U.S. Node 2 known as Harmony.
This is one of a series of images showing various parts of space shuttle Atlantis in Earth orbit as the shuttle performed a backflip for the rendezvous pitch maneuver.
Atlantis is seen over the Bahamas prior to a perfect docking with the ISS. Part of a Russian Progress spacecraft that is docked to the station is in the foreground.
Spacewalker Mike Fossum rides on the ISS robotic arm as he carries the Robotic Refueling Mission experiment on the final scheduled spacewalk during a shuttle mission.
