EchoStar XXI (formerly known as TerreStar 2^[2]) is a European communications satellite which is operated by Echostar Corporation. It was constructed by Space Systems/Loral, based on the SSL 1300 satellite bus, and carries S band transponders which will be used to provide 2 GHz mobile connectivity throughout Europe.

EchoStar XXI was launched at 03:45 UTC on June 8, 2017^[3] from the Baikonur Cosmodrome in Kazakhstan. This satellite was the heaviest commercial payload flown aboard a Russian booster at the time of its launch.^[4]

Before being launched, the satellite was known as TerreStar-2, a ground spare for TerreStar Networks' satellite-terrestrial telephone network.^[5]
