ECHOSTAR 21, formerly known as TerreStar 2, is a communications satellite under commercial operation by the EchoStar Corporation, hosting an S-Band payload operating in the previously unavailable 2 GHz band to deliver mobile connectivity throughout Europe. Built by Space Systems/Loral in Palo Alto, California, the ECHOSTAR 21 satellite weighed around 15,200 pounds (6.9 metric tons) at liftoff, making it one of the most massive commercial communications craft ever launched, and the heaviest commercial payload ever flown on a Proton rocket. ECHOSTAR 21 will enter service in geostationary orbit at 10.25 degrees east longitude.
