SES-11 / EchoStar 105 Set To Launch Tonight

The SES-11 / EchoStar 105 mission by SpaceX is set to launch this evening. The launch window opens at 6:53 pm and closes at 8:53 pm. SpaceX will launch the SES-11 satellite aboard their Falcon 9 rocket from launch complex 39A at the Kennedy Space Center.  Following the stage separation, SpaceX will attempt to land the Falcon 9 first stage on the autonomous drone ship “Of Course I Still Love You”, which will be positioned in the Atlantic Ocean. The communications satellite will be deployed about 36 minutes after the launch.

A SpaceX Falcon 9 rocket will deliver the EchoStar 105 / SES-11, a commercial communications satellite, into Geostationary Transfer Orbit (GTO). EchoStar 105 is a high powered hybrid Ku and C-band communications satellite, is a dual mission satellite for US-based operator EchoStar and Luxembourg-based operator SES. The communications satellite provides EchoStar with 24 Ku-band transponders of 36 MHz, marketed as EchoStar 105, all while providing SES with a C-band payload of 24 transponders, marketed as SES-11. 

EchoStar 105 was designed to meet the Ku-band capacity needs of EchoStar’s enterprise, media and broadcasting and U.S. government service provider customers, offering coverage for all 50 U.S. states and expanded to reach the Gulf of Mexico and the Caribbean. 

SES-11 was designed to accelerate the development of SES’s U.S. prime video neighborhood and the delivery of HD and UHD channels. SES-11 joins SES-1 and SES-3 at the center of SES’s robust North American orbital arc, which reaches more than a hundred million television subscribers. The satellite will also replace the C-band capacity of AMC-18, which SES offers over North America, including Hawaii, Mexico, and the Carribean, empowering businesses and governments to capture new opportunities and expand their business. 

We will be posting the SpaceX live stream for the launch later today. Meanwhile, you can check out the mission gallery for photos and videos related to this launch.
