Astronaut Robert L. Behnken used a digital camera to take this self-protrait during a spacewalk. Also visible in the visor's reflections are components of the station, the docked space shuttle Endeavour and a blue and white portion of Earth. During the nearly 7-hour spacewalk, Behnken and astronaut Rick Linnehan, installed a spare-parts platform and tool-handling assembly for the Special Purpose Dextrous Manipulator also known as Dextre. Among other tasks, they also and calibrated Dextre's end effector and attached critical spare parts to an external stowage platform. The new robotic system was activated on a power and data grapple fixture located on the Destiny laboratory on flight day nine. Image Credit: NASA
