Astronaut Mike Fossum used a digital camera to create this self-portrait during the STS-124 mission's first scheduled spacewalk. During the six-hour, 48-minute spacewalk, Fossum and fellow astronaut Ron Garan prepared the Kibo Japanese Pressurized Module for its installation to the space station. Kibo was officially opened during a ceremony performed by astronaut Akihiko Hoshide and the Expedition 17 and STS-124 crew the following day, Wednesday, June 4, 2008. During the spacewalk, Fossum and Garan also loosened restraints holding the Orbiter Boom Sensor System in its temporary stowage location on the space station's starboard truss, demonstrated cleaning techniques for the Solar Alpha Rotary Joint's (SARJ) race ring and installed a replacement SARJ Trundle Bearing Assembly.
