P1 Truss and JEM Pressurized Module (JPM)

S119-E-007519 (23 March 2009) --- Astronaut Richard Arnold (lower left on port truss), STS-119 mission specialist, participates in the mission's third scheduled session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 27-minute spacewalk, Arnold and Joseph Acaba (out of frame), mission specialist, helped robotic arm operators relocate the Crew Equipment Translation Aid (CETA) cart from the Port 1 to Starboard 1 truss segment, installed a new coupler on the CETA cart, lubricated snares on the "B" end of the space station's robotic arm and performed a few "get ahead" tasks. The Japanese Kibo laboratory is visible at right, and the station’s Canadarm2 is at left. The blackness of space and Earth’s horizon provide the backdrop for the scene.
