The launch of XM-2/Rock placed a commercial digital radio broadcast satellite into Geosynchronous Transfer Orbit. The weight of the spacecraft, fully fueled at the time of launch, was 10,287 lbs (4,666 kg). Launching from its equatorial launch site at 154 degrees West Longitude at 2:33:30 pm PST, Sea Launch inserted the spacecraft directly into Geosynchronous Transfer Orbit.
All systems onboard the three-stage expendable launch vehicle performed nominally. The Block DM upper stage separated from the spacecraft some 1,600 miles over the Indian Ocean, one hour and five minutes into the mission. Operators at a ground station in Perth, Australia, acquired a signal from the satellite at approximately 3:43 p.m. PST. XM-2 is now operating in its final position in Geostationary Orbit at 115 degrees West Longitude.
