Astronaut Robert L. Behnken, STS-123 mission specialist, participates in the mission’s third scheduled spacewalk. During the 6-hour, 53-minute spacewalk, Behnken and Rick Linnehan installed a spare-parts platform and tool-handling assembly for Dextre, also known as the Special Purpose Dextrous Manipulator. Among other tasks, they also checked out 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. The blackness of space and Earth’s horizon provide the backdrop for the scene.Image Credit: NASA
