It’s been standard procedure for the space shuttle to make a fly-around and take pictures of the International Space Station just as it’s pulling away for the homeward journey. But the procedure was changed for this month’s very last visit by the space shuttle Atlantis.

After the shuttle backed 600 feet away, pilot Doug Hurley held it in position while the space station rotated 90 degrees to the right. Then Hurley made a half-loop around the station, to give Atlantis’ crew members an opportunity to snap pictures of the station from angles never before photographed during a fly-around.

Here are some of the high-resolution pictures. Scores of additional images focus in on details that NASA engineers wanted to check. “The images will be evaluated by experts on the ground to get additional information on the condition of the station’s exterior,” NASA said.
