July 17, 2009 (Flight Day 3, ISS Docking)

This view of the underside of the crew cabin of the Space Shuttle Endeavour was provided by an Expedition 20 crewmember during a survey of the approaching vehicle prior to docking with the International Space Station. As part of the survey and part of every mission's activities, the STS 127 Endeavour crew performed a back-flip for the rendezvous pitch maneuver (RPM). The image was photographed with a digital still camera, using a 400mm lens at a distance of about 600 feet (180 meters).
