Really Rocket Science

No rocket on the platform means it lifted off:

A Zenit-3SL rocket lifted off at 2:43am PDT (9:43 GMT) from the Odyssey Launch Platform, positioned at 154 degrees West Longitude, precisely on schedule. An hour later, the Block DM-SL upper stage inserted the 4,642 kg (10,234 lb) Galaxy 18 satellite into geosynchronous transfer orbit, on its way to a final orbital position at 123 degrees West Longitude. Operators at the Hartebeesthoek ground station in South Africa acquired the spacecraft’s first signals from orbit shortly after spacecraft separation. All systems performed nominally throughout the mission.
