SpaceX launched a new era for its company.
Part of the reason we've gone so long without seeing a SpaceX landing is that the company has been trying to get rid of its excess Block 4 rockets by refusing to land them back on Earth.
Just like with Block 5's first-ever spaceflight, the first stage will be making an ocean landing after delivering its satellite payload and is set to touch down on a SpaceX "Of Course I Still Love You" drone ship.
What's important about the newly configured Block 5 version is that it designed for multiple re-uses, probably up to around 10 launches per rocket, and without major refurbishment.
This time around, it will be Canada's Telstar 19V satellite that makes the trip to high, geostationary orbit atop a "Block 5" Falcon 9 rocket.
Telesat is positioning Telesat-19 Vantage at 63 degrees West, the same orbital slot as its seven-year-old Ku-band Telstar-14R satellite.
The Block 5 Falcon 9 lifted off from Cape Canaveral Air Force Base in Florida at 1:50 a.m. Eastern Time from the Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. It is the first of two satellites built by California-based company SSL.
"Telstar 19 Vantage will also be able to provide Internet connectivity to those in rural and remote areas, and even coverage over the North Atlantic Ocean, which is super-important when it comes to providing Internet access for commercial airlines and cruise ships".
The almost 15,600-pound (7,075-kilogram) spacecraft is the heaviest commercial communications satellite ever launched.
Also published video of the launch. It will launch the Merah Putih and the Telstar 18 Vantage or 18V communications satellites in August.
