SpaceX invented the third attempt to takeoff and landing bold [Updated]

Update: After the engines began firing, only a fraction of a second before the launch, flight computers aboard the Falcon 9 rocket encountered a problem and shut down the launch sequence down. SpaceX had appointed Monday for a launch attempt backup, but now that is awaiting a determination of what went wrong during the countdown Sunday.

Original Post: Twice SpaceX attempt to launch the SES-9 communications satellite into space last week, and twice the rocket company had to scrub. The reason was not time, but rather problems with ensuring that the rocket was fueled with the right amount of liquid oxygen postponed the festivities.

With its new more powerful variant ,, SpaceX Falcon 9 rocket is to have to handle this, dense super-cold propellant with more care, and one of the things you're trying to do is deliver the right amount of fuel just before launch . With near perfect weather conditions expected for release today, you find that this is the main problem to see how SpaceX countdown to the 18:46 ET (23:56 UK) opening of the launch window.

As with other recent releases, SpaceX will try again to fly its reinforcement back to an automated ship in the Atlantic Ocean off the coast of Florida. However, because this is a high orbit (about 35,000 kilometers above the Ecuador) and will require a heavy vehicle with more fuel and more speed, return safely to Earth it is far from assured. In addition, at 5,300kg, this is the heaviest burden SpaceX has tried to deliver a geostationary orbit.

Still, the company says it will make another attempt at a historical first, landing an orbital rocket on a platform based on the sea. "The first stage of the Falcon 9 will try an experimental landing in the 'Of course I still love' droneship," SpaceX said in his press kit. "Given the unique profile of this mission GTO a successful landing is not expected."

The webcast then begin at approximately 18:25 ET (23:25 UK).
