Astronaut Mike Fossum, STS-124 mission specialist, participates in the mission's first scheduled session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. Visible in the reflections of his helmet visor are various components of the station, Earth's horizon and astronaut Ron Garan, mission specialist. During the six-hour, 48-minute spacewalk, Fossum and Garan loosened restraints holding the Orbiter Boom Sensor System in its temporary stowage location on the space station's starboard truss, prepared the Kibo Japanese Pressurized Module for its installation to the space station, demonstrated cleaning techniques for the Solar Alpha Rotary Joint's (SARJ) race ring, and installed a replacement SARJ Trundle Bearing Assembly.
