SpaceX launches world's heaviest communications satellite
Elon Musk-led space startup SpaceX on Sunday launched the Telstar 19 Vantage satellite, the world's heaviest commercial communications satellite weighing over 7,000 kg, through its Falcon 9 rocket. Its upgraded first stage booster flew itself back and landed on an off-shore droneship. This was the second successful launch of the new version of SpaceX's Block 5 rocket.
