Countdown clocks tick to 7:34 a.m. launch

Countdown clocks have picked up at the Cape Canaveral Air Force Station and launch of the Delta 2 rocket and NASA's Dawn spacecraft remains scheduled for 7:34 a.m.

A stray boat has moved out of the Launch Hazard Area off the coast and the International Space Station now is clear of the flight path that the Delta 2 will be flying through.
