A Herculean liftoff Nine Hercules Aerospace solid rocket motors help lift a 12 1/2-story Delta II rocket from Cape Canaveral in Florida Friday night that will launch a $40 million communications satellite into a 22,220-mile orbit. This was the third successful Delta II launch; the current Hercules contract involves 16 flights and 144 motors. The new graphite epoxy motors are 6 feet longer and add 15 percent more lift capability.
