Minus-7 minutes and counting. The synchronized sequence has started. Computers are now in control of this automated final phase of the launch countdown to prepare the rocket and ground systems for liftoff. There are three computers running the countdown - one aboard the Ariane 5 and two redundant computers at the launch complex.

The launch time is set for 1930:00 GMT (3:30:00 p.m. EDT; 4:30:00 p.m. French Guiana time). Liftoff actually occurs even seconds later with ignition of the solid rocket boosters.

Minus-5 minutes. All status panel lights remain green, indicating no problems right now that could prevent blastoff.
