STS-117 astronauts and mission specialists Patrick Forrester and Steven Swanson (out of frame), participated in the second Extra Vehicular Activity (EVA) as construction resumed on the International Space Station (ISS). Among other tasks, the two removed all of the launch locks holding the 10 foot wide solar alpha rotary joint in place and began the solar array retraction. The primary mission objective was the installment of the second and third starboard truss segments (S3 and S4).
