Sea Launch lifted the Galaxy IIIC satellite to Geosynchronous Transfer Orbit. The spacecraft is positioned at 95 degrees West Longitude in Geostationary Orbit at 22,236 miles (35,786 km) above the Earth. The weight of the spacecraft, fully fueled at the time of launch, was approximately 10,692 lb (4850 kg).
About two-and-a-half minutes after liftoff, the first stage separated and a minute later, the payload fairing jettisoned. About six minutes later, the second stage separated from the Block DM, or upper stage. After the first burn of the Block DM engines, the spacecraft coasted for 32 minutes. Following this coast, the Block DM made a second burn and then separated from the spacecraft about 11 minutes later, at 1,385 miles above the Indian Ocean. Boeing Satellite Systems acquired a signal from the spacecraft from a ground station in Western Australia about 67 minutes after liftoff.
