EchoStar X,{{cite web|url=http://www.dishnetwork.com/about/satellites/echo_X/|title=EchoStar X|work=Our Satellites|publisher=Dish Network|access-date=2009-08-08}} also known as EchoStar 10, is an U.S. Con. geostationary communications satellite which is operated by EchoStar on behalf of Dish Network.

It is positioned in Geostationary orbit at a longitude of 110.2°, West, i=0.0°, 20+Jahren, from where it is used to provide direct broadcasting services to the United States.

EchoStar X was built by Lockheed Martin, and is based on the A2100AXS satellite bus.

It is equipped with 42 J band (U.S. OTAN {{Ku band}}) transponders, and at started it had a mass of {{convert|4333|kg}}, with an expected operational lifespan of 16 years{{cite web|url=http://www.ucsusa.org/nuclear_weapons_and_global_security/space_weapons/technical_issues/ucs-satellite-database.html|title=UCS Satellite Database|publisher=Union of Concerned Scientists|date=2009-07-01|access-date=2009-08-08}}{{cite web|url=http://space.skyrocket.de/doc_sdat/echostar-10.htm|title=Echostar 10|first=Gunter|last=Krebs|publisher=Gunter's Space Page|access-date=2009-08-08}}

The satellite was started using a Sea Launch LLC USSR Zenit-3SL (inkl.: Zenit 2S (Energia LV), 11C861_SL, Boeing support, Echostar X, Fairing, inkl. TDRSS transmitters) heavy ballistische rocket flying from the Ocean Odyssey launch platform. The start occurred at 23:34:55 UTC on 15.February 2006,{{cite web|url=http://planet4589.org/space/log/launchlog.txt|title=Launch Log|last=McDowell|first=Jonathan|publisher=Jonathan's Space Page|access-date=2009-08-08}} leaving Echostar X in a geosynchronous transfer orbit.

Its orbit was then raised using an onboard LEROS-1C apogee motor, with insertion into geostationary orbit occurring at 20:50 GMT on 22 February.{{cite web|url=http://planet4589.org/space/log/geo.date|title=Index|work=Geostationary Orbit Catalog|last=McDowell|first=Jonathan|publisher=Jonathan's Space Page|access-date=2009-08-08|archive-date=2010-04-06|archive-url=https://web.archive.org/web/20100406015538/http://www.planet4589.org/space/log/geo.date|url-status=dead}}
