Storm Possiblity Delays RSS Retract

In anticipation of a storm that is predicted to pass over NASA Kennedy Space Center this evening, technicians at Launch Pad 39A will delay the opening of the rotating service structure (RSS) away from space shuttle Endeavour until approximately 8:30 p.m. EDT. Teams currently have begun support work that normally occurs following the RSS move, which allows the countdown to continue as planned to support Friday's 3:47 p.m. launch.
