The Intelsat 39 geosynchronous communications satellite has safely arrived at the Arianespace launch base in Kourou, French Guiana, after completing final delivery checkouts at Maxar’s Palo Alto, California manufacturing facility. Intelsat 39 is the 52ndsatellite built by Maxar for our long-term customer, Intelsat. The Intelsat, Arianespace and Maxar teams in Kourou will now prepare the satellite for launch on an Ariane 5 rocket, which is currently scheduled for July 24.  

Once it reaches its final destination at 62 degrees East, the satellite will provide broadband and video distribution services across Africa, Europe, the Middle East and Asia. The satellite will also enhance mobile connectivity for aero, maritime and government users operating in the Indian Ocean region.  

Intelsat 39 will replace the Intelsat 902 satellite, which was also built by Maxar and launched in 2001. By the time of its replacement by Intelsat 39, Intelsat 902 will have exceeded its expected 13-year design life by six years, or 45%. 

Intelsat 39 is based on Maxar’s decades-proven 1300-class platform, which offers high power, reliability and flexibility to support a broad range of applications and technology advances. 

The satellite has both C-band and Ku-band transponders, and will use hybrid electric and chemical propulsion to reach its desired orbit, where it is designed to provide service for a minimum of 15 years. Once on-orbit, the satellite will maintain its position using all-electric propulsion, which provides efficiency for satellite operators by reducing launch mass while increasing spacecraft flexibility and performance. 

A video of the launch will be livestreamed at, and Maxar will be posting frequent updates on Twitter, LinkedIn and Facebook as the satellite progresses through launch and into operations.
