SpaceX continues to record, launching large satellites

After 8 minutes and 29 seconds after start, the first stage will include three engines to brake the fall into the ocean - the satellites will sit on a platform in the Atlantic.

This morning, July 22 at 08:50 Kiev time, SpaceX will open a four-hour window to launch a Falcon 9 booster rocket with Canadian satellites on board. If weather and equipment permit, take-off will take place right at the moment

The launch of the thirteen Ilona Mask space companies in 2018 will be the record: the mass of Telstar 19 Vantage - 7080 kg. This is the heaviest satellite Falcon 9 ever brought into geostationary orbit.

The takeoff will take place from the SLC-40 US Air Force base site at Cape Canaveral. After the new parade of B1047 is built, it will be gently planted on unmanned offshore platform "Of course I still love you". This is only the second flight of Falcon 9 in the last version of Block 5 - whereby the first enhanced stage can be used not twice,as before, but up to 100 times; The first launch of a "new" missile was successfully carried out on May 11th.

Interestingly, the next Falcon 9 launch will take place in three days.

45 seconds before the "T-0" time, the launch director will give the command "on take-off" - the entire operation is controlled by the computer from the moment. When the countdown reaches the "three" starting ignition for all nine Merlin-1D engines, the word "start" forces them enough for take-off. About 72 seconds of missile flights will take the maximum aerodynamic load (where speed and air resistance cause the largest mechanical stress bearing structures) - the so-called Max-Q dots.

After 150 seconds of flight, flight stage will die and after three more seconds will be disconnected (MECO point).

Another second will pass - the second stage engine will start. 56 seconds later, the dynamite bolt from the cone of the nose will explode - and the two doors will fall into the sea with a parachute; they will come out of the water. In the next mission, to be held in California, the fairing will be caught in a net on board a ship. Steven in the Pacific.

The first start of the second stage of the machine will last 5 minutes 38 seconds - until the "parking" orbit (reference), after which it will move with inertia for 18 minutes and 20 seconds. Then the machine will turn on for a second time (for 50 seconds) to send the object a push to exit into geostationary orbit. After 5 minutes 1 sec after turning off the engine (SECO point), the satellites will be placed at the planned orbital point. This will happen in 32 minutes 40 seconds from the start of the launch.

Telstar 19V will be located in Brazil: a signal from it will provide services to users in South America, the Caribbean islands, northeastern Canada and the North Atlantic. The expected time of his job is at least 15 years.

Note that SracheX rockets are collected in a "lying" position in the hangar near the launch pad, after which they are transported and placed vertically with the help of a strong lever:
