SpaceX's Falcon 9 rocket is expected to take off from Cape Canaveral on Monday, heading east over the Atlantic Ocean to deliver the Telstar 19 VANTAGE telecommunications satellite in orbit around 32 minutes later [19659002The229-high-tall(70-meter)isreadyforlaunchfromPad40attheCapeCanaveralAirStationinFloridaat12:50pmEDT(4:50GMT)Sundayattheopeningofawindowfourhourlaunch

Perched at the top of the rocket is the Telstar 19 VANTAGE satellite communications, a spacecraft manufactured by SSL – formerly known as Space Systems / Loral – and owned by Telesat based in Ottawa

Telstar 19 VANTAGE weighs 15 597 pounds (7,075 kilograms) with its fully loaded propellant tanks. the heaviest commercial communications satellite ever launched.

The Canadian satellite, built by the United States, will carry Ka-band and Ku-band broadband services over the Americas from northern Canada to South America. g Wi-Fi in flight for airliners circulating in the North Atlantic Ocean. Telstar 19 VANTAGE is designed for a 15-year mission, and it's the first of two spacecraft built by SSL and owned by Telesat to be launched on SpaceX Falcon 9 rockets.

After the deployment of the In the upper stage of the Falcon 9 rocket, an elliptical transfer orbit, Telstar 19 VANTAGE will use its onboard hydrazine engine to propel itself into a circular geostationary orbit of more than 36,000 kilometers above sea level. ; equator.

The launch of the Falcon 9 Telstar 19 VANTAGE rocket will fly into the improved "Block 5" configuration. This will be the second launch of Falcon 9 Block 5 after the launch of the new rocket version in May

The timeline below describes the launch sequence of Falcon 9 flight with Telstar 19 VANTAGE.

T + 0: 32: 40: Telstar 19 VANTAGE Separation

The SES 9 spacecraft separates from the Falcon 9 rocket in an orbit with a culminating point of about 39,300 kilometers, a low point of 290 kilometers and an inclination of 28 degrees. Due to the decision to burn the second stage almost to the point of exhaustion, there is a slight uncertainty about the orbital parameters based on the exact performance of the launcher.
