T-4 Minutes and Counting

The NASA launch conductor has polled mission managers for “go” to launch. The Lucy countdown is now underway, proceeding toward a liftoff at 5:34 a.m. EDT. During the last four minutes of the countdown, the Atlas and Centaur propellant tanks will be brought up to flight pressure, the rocket and spacecraft will be confirmed on internal power, and the Eastern Range and launch managers will perform final status checks. A computerized auto sequencer will take over the countdown in order to conduct a host of activities in precise order. Weather conditions are still good for launch.
