Telstar 19V (Telstar 19 Vantage) is a communication satellite in the Telstar series of the Canadian satellite communications company Telesat. It was built by Space Systems Loral (MAXAR) and is based on the SSL-1300 bus. The satellite was designed to provide additional capacity over the North Atlantic region.[2] As of 26 July 2018, Telstar 19V is the heaviest commercial communications satellite ever launched, weighing at 7,076 kg (15,600 lbs)[3] and surpassing the previous record, set by TerreStar-1 (6,910 kg/15230lbs), launched by Ariane 5ECA on 1 July 2009.


Telstar 19V was launched on a SpaceX Falcon 9 Block 5 rocket into geostationary transfer orbit (GTO) from Space Launch Complex 40 (SLC40) at Cape Canaveral Air Force Station, Space Coast, Florida, United States, on 22 July 2018 at 1:50 AM EDT (5:50 UTC).[4] The rocket core landed on the autonomous spaceport drone ship about eight and a half minutes after liftoff.
