The rocket operator released a time-lapse video on Sunday showing the Atlas V rocket moving from the Vehicle Assembly Building to the launchpad at Cape Canaveral in Florida. ULA chief Tory Bruno noted that while the rocket appears to hurtle to its destination, the vehicle carrying it is actually moving at a mere 3 mph.
