SpaceX launched just its second "block 5" Falcon 9 rocket in the darkness from Florida early Sunday local time, and it was loaded with the heaviest commercial communications satellite ever built. 

The brand new booster blasted off from Cape Canaveral at 1:50 a.m. ET carrying the Telstar 18 Vantage broadband satellite, a 15,600-pound (7,076 kilogram) beast that will offer connectivity to customers in the Americas.
