Echostar 12 (E*12), also known as Cablevision-1 and Rainbow-1, is a commercial communications satellite in geosynchronous Earth orbit. It was launched on 17 July 2003, as Rainbow-1, on the third flight of the Atlas V rocket from Cape Canaveral, Florida. Its original purpose was to transmit digital television streams for the ill-fated Voom high definition direct broadcast satellite network.
