The crew is at the center for Crew Equipment Interface Test activities, which involves equipment familiarization, a routine part of astronaut training and launch preparations. The mission will deliver the second port truss segment, the P3/P4 Truss, to attach to the first port truss segment, the P1 Truss, as well as deploy solar array set 2A and 4A. Launch on Space Shuttle Atlantis is scheduled for late August. Photo credit: NASA/Kim Shiflett KSC-06pd1188
