The STS-117 and Expedition 15 crews are moving through a busy day aboard
the International Space Station and Space Shuttle Atlantis. They have
been retracting solar arrays and preparing for STS-117’s third spacewalk.
The STS-117 crew resumed retraction of the starboard P6 solar array at
12:25 p.m. today. The crew and flight controllers decided to conclude
the efforts just before 2000 UTC. with about half of the 31½ array bays
retracted. The crew will resume retraction activities Friday with the
help of the spacewalkers if needed.
The schedule for STS-117 Mission Specialists Jim Reilly and Danny Olivas
includes a review of procedures and the practice of techniques they will
