Space X, Falcon 9

SpaceX has postponed the launch of the sixth mission which was scheduled for telecommunications giants SES to add some extra work on the second stage. The launch will now be on June 4th, 2018 from Florida’s Cape Canaveral Air Force Station and it will be using a flight-proven Falcon 9 rocket which will help in deploying the SES-12 satellite into the geostationary transfer orbit.

The launch of SES-12 will be SpaceX’s eleventh mission of the year, and it will continue to be in partnership with Luxembourg-based SES. SES was the first customer to launch a communication satellite with the help of the Falcon 9 rocket in the year 2013. SES-12 will be reusing the Falcon 9, whose first stage was previously part of the rocket that was deployed by one of the US Air Force X-37B Spaceplanes during last September.

The SES-12 payload weighs about 5,400 Kg communication satellites which carry about 76 ka and Ku band transponders. , and it is built around the Eurostar E3000e platform which is also a variant of Airbus Eurostar 3000 product line. This relies solely on electric propulsion for orbiting the raising manoeuvre.

When the Falcon deploys the satellites in orbit, SES-12 will be using its SPT-140D thrusters, and it was manufactured by Russia’s OKB Fakel which raises itself to geostationary orbit. This process was expected to about six months, and the satellite will be operating for at least 15 years.

SES-12 satellite will replace the 15-year-old NSS-6 satellite, and it will be stationed in geostationary orbit at a longitude of about 95 degrees East, and from there it will provide direct-to-home broadcasting and high-throughout satellite services to Asia, Australia, and the Middle East, and it will also be the parts of Eastern Europe, East Africa, and the Mediterranean.

SpaceX has planned to recover the rocket’s fairing, and the first stage will not be recovered. The fairing is the nose cone of the Falcon 9 which protect the satellite when the rocket goes towards space, and it cost about 6 million dollars per launch. The company has failed to catch fairing in the recent launch, but it is determined that this time it can catch the fairing with the help of the giant net which was mounted on a boat named Mr.Steven.
