Echostar 12 (E*12), also known asCablevision-1 andRainbow-1, is a commercialcommunications satellite ingeosynchronous Earth orbit. It was launched on 17 July 2003, as Rainbow-1, on the third flight of theAtlas V rocket fromCape Canaveral,Florida. Its original purpose was to transmitdigital television streams for the ill-fatedVoom high definitiondirect broadcast satellite network.

Part of theA2100 series of commercial satellites, Rainbow-1 was constructed by theLockheed Martin corporation at an approximate cost of $100 million USD,[1] although this amount has not been verified. It issolar powered, has an approximatemass of 2,760 kilograms (6,080 lb) (launch vehicle mass 4,328 kilograms [9,542 lb]), and is capable of transmitting on theC- andKu bands.

EchoStar (Dish Network spin off) now owns the satellite. The satellite was renamed Echostar 12 (or E*12) in March 2006.

EchoStar 12 is still in orbit and located at 61.5 degrees West longitude, over the Earth's equator.[2][3] It is currently being used for Dish NetworkHDTV television signals, transmitted usingDVB, on the Ku band transponders. The satellite has lost some capability due to degradation of its solar power system.[4]
