Second workhorse left the stable

SpaceX got commissioned by Telesat to send the Telstar 19 Vantage satellite towards its parking orbit. SpaceX will be launching the satellite on top of one of their Falcon 9 rockets. The rocket is currently at Cape Canaveral Air Force Station at the launch pad SLC-40.

SpaceX will be launching the Telstar 19 Vantage satellite to Geostationary Transfer Orbit (GTO) on top of SpaceX’s work-horse rocket. The Falcon 9 will launch from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, in Florida. The booster supporting this mission is on its maiden voyage - B1047-1, and will land 635 km downrange aboard SpaceX’s autonomous spaceport drone ship ‘Of Course I Still Love You.’

The fairings are not going to be recovered, because there are no parachutes mounted on the fairings. They will burn up on reentry some 700 km downrange.

The Payload

Telstar 19 Vantage is a communication satellite in the Telstar series of the Canadian satellite communications company Telesat. T19V will be equipped with C and Ku-band transponders and operate from 63° West.

At 7 076 kilograms (15 600 lb), it is the heaviest communication satellite ever launched, weighing just about 15 kilos more than its sibling Telstar 18V. End of life mass or dry mass after 15 years of station keeping is stated to be 3 031 kilo gives us the information that there is 2 045 kilo of propellant mass in the Telstar 19 VANTAGE satellite.

Telesat signed with SSL in December 2015 for the construction of the satellite. It will be based on the SSL-1300 bus with an electrical output of approximately 14 kW.

The satellite Telstar 19 VANTAGE will operate from 63° West and significantly expand Telesat’s capacity over the American region through a combination of broad regional beams and high throughput spot-beams.

Telesat also announced it has entered into an agreement with APT Satellite Company Limited (APSTAR) under which APSTAR will make use of capacity on Telstar-19 VANTAGE to serve its growing base of customers. This agreement extends the long term relationship between APSTAR and Telesat that has existed for more than a decade.

Equipped with C and Ku-band transponders, Telstar 19 VANTAGE will offer superior performance for broadcasters, telecom service providers and enterprise networks on the ground, in the air and at sea. Its broad C-band coverage will extend across the Asia region to Hawaii enabling direct connectivity between any point in Asia and the Americas. Its Ku-band capacity will expand on Telesat’s coverage of growing satellite service markets in China, Mongolia, Southeast Asia, and the Pacific Ocean.

Prelaunch Previews or Mission Rundowns

This is the first sign of a Tim Dodd’s Prelaunch Preview, which I'm trying to revive by copying those Previews, which went missing during the website's update in January 2021, and I went all the way back in time to 2010 and did it on all Falcon 9 flights/missions.

I had glued my eyes to the screen trying to catch a glimpse of the original Preview, but alas I have sometimes done my own thing with the help of Wikipedia, Google and other sources regarding the launches and development of Falcon 9.

Since February 2021 I have made other changes to these Prelaunch Previews, they are written with 20 x 20 hindsight, so they are POSTLAUNCH Mission Rundowns, and there is recovered information placed in it. What was known then is different from present day knowledge about the launch, and that will show itself.

I’m entering my own observations on technical details by answering questions posted by Paetron supporters and Superchat inputs. They are found under the title:

Now that’s a good question

And I’m trying to figure out just how a SpaceX Falcon 9 works, how it changed and how it’s constructed by checking measurements, volumes, thrust, block changes and a lot of other details. For instance the Merlin 1D has gone through 4 iterations giving it 4 thrust changes expressed in 1D, 1D+, 1D# and 1D#, first the regular design D, then the super chilled design change D+, then it got the throttle down design change D# and lastly there was the change of the turbopump shaft propeller D# giving its current thrust capability.

Being in Corona isolation since the start of this year 2021 gave the time, and I was curious about just how high a Falcon 9 was with a Crew Dragon on top. There are other things not quite accurate in wikipedia, so I have watched all Youtube videos a number of times, and Tim Dodd is one of the more informative sources out there.

I have found more sources during this half year scattered all over these pages. And done now four edits on these pages about Falcon 9 so far.

This fifth edit is about changing my internal links from google docs to my blog, and to have my blog links be dominering over Tim Dods Everyday Astronaut links. They are still available from January 2021 as the booster's previous flights or missions.
