At Launch Complex 40 on Cape Canaveral Air Station, the Mobile Service Tower is being rolled away from the Titan IVB/Centaur launch vehicle carrying the Cassini spacecraft, completing a major countdown milestone. This is the second launch attempt for the Saturn-bound mission; a first try Oct. 13 was scrubbed primarily due to concerns about upper level wind conditions. Liftoff Oct. 15 is set to occur during a launch window opening at 4:43 a.m. EDT and extending until 7:03 a.m
