EchoStar X was built by Lockheed Martin, and is based on the A2100AXSsatellite bus. It is equipped with 42 J band (IEEE Ku band) transponders, and at launch it had a mass of 4,333 kilograms (9,553 lb), with an expected operational lifespan of 16 years[2][3]
The satellite was launched using a Sea LaunchZenit-3SL carrier rocket flying from the Ocean Odyssey launch platform. The launch occurred at 23:34:55 GMT on 15 February 2006,[4] leaving Echostar X in a geosynchronous transfer orbit. Its orbit was then raised using an onboard LEROS-1Capogee motor, with insertion into geostationary orbit occurring at 20:50 GMT on 22 February.[5]
Launches are separated by dots ( • ), payloads by commas ( , ), multiple names for the same satellite by slashes ( / ). Crewed flights are underlined. Launch failures are marked with the † sign. Payloads deployed from other spacecraft are (enclosed in parentheses).
