Falcon 9 launches timeline with Telstar 19 VANTAGE – Spaceflight Now



The SpaceX Falcon 9 rocket is due to launch from Cape Canaveral on Monday and fly eastward across the Atlantic to bring the Telstar 19 VANTAGE communications satellite into orbit about 32 minutes later

(R) is ready for the launch of Pad 40 at Cape Canaveral Air Force Station in Florida at 12:50 pm EDT (0450 GMT) Sunday at the opening of a four-hour launch window

The Telstar 19 VANTAGE communications satellite, a spacecraft crafted by SSL – formerly known as Space Systems / Loral – and owned by Ottawa-based Telesat.

Telstar 19 VANTAGE weighs 15,597 kilograms (7,075 kilograms) with fully loaded fuel tanks The US-built, Canadian-owned satellite will ship Ka-band and Ku-band broadband services across North and South America from North Canada to South America, with additional coverage (1

9659002) g In-Flight WLAN for aircraft traveling in the North Atlantic. Developed for a 15-year mission, Telstar 19 is the first of two satellites owned by Telesat to launch SpaceX Falcon 9 rockets.

After deploying the Falcon 9 rocket's upper stage into an elliptical transfer orbit, Telstar 19 VANTAGE will use its on-board hydrazine-powered engine to propel itself into a circular geostationary orbit more than 22,000 miles above the equator ,

The Falcon 9 launches Telstar 19 VANTAGE will fly in the updated "Block 5" configuration. It will be the second launch of Falcon 9 Block 5 after the new missile release debuted in May.

The timeline below outlines the launch sequence for the Falcon 9 flight with Telstar 19 VANTAGE.

  The SES 9 satellite separates itself from the Falcon 9 rocket in an orbit with a predicted peak of about 39,300 kilometers (24,400 miles), a nadir of 290 Kilometers (180 miles) and a slope of 28 degrees. Due to the decision to burn the second stage to near exhaustion, there is some uncertainty about the orbital parameters based on the exact performance of the launch vehicle.
