The launch can be watched starting 20 minutes before launch time, at Arianspace’s Video Corner.

The Ariane-5ECA is 50.5 meters tall and will weigh in at about 780 tons at lift off, requiring over 400 tons of fuel to ramp the beast up to over 2900 pounds of fource to lift-off.

The payload, a Japanese television (JCSAT-10) and French military communications (SYRACUSE 3B) satellites, is expected to be in operation for between 15 and 12 years, respectively.
