XM-4 Satellite Sea-Launched


The XM-4 satellite was successfully launched on Monday:

A Zenit-3SL vehicle lifted off at 3:49 pm Pacific Standard Time (23:49 GMT) from the Odyssey Launch Platform, positioned at 154 degrees West Longitude in the equatorial Pacific. All systems performed nominally throughout the flight. The Block DM upper stage inserted the 5,193 kg (11,448 lbs.) spacecraft into geosynchronous transfer orbit, on its way to final orbital position of 115 degrees West Longitude. A ground station at Hartebeesthoek, near Pretoria, South Africa, acquired the first signal from the satellite in orbit.

I think you’ll enjoy the video.
