From across the turn basin can be seen Space Shuttle Atlantis approaching the Vehicle Assembly Building (at left). Atlantis is rolling back to the VAB from Launch Pad 39A. In the VAB workers will conduct inspections, make continuity checks and conduct X-ray analysis on the 36 solid rocket booster cables located inside each booster’s external system tunnel. An extensive evaluation of NASA’s SRB cable inventory revealed conductor damage in four (of about 200) cables on the shelf. Shuttle managers decided to prove the integrity of the system tunnel cables already on Atlantis before launching. The launch has been rescheduled no earlier than Feb. 6.
