SpaceX successfully launches its first attempt at geosynchronous orbit
Early this evening in Florida, space transport company SpaceX successfully launched its Falcon 9 rocket on a trajectory to place a satellite in geosynchronous orbit. The success comes on the third attempt, with one of the previous tries getting as far as engine ignition before shutting down. If the remaining maneuvers are completed successfully, the launch will place a commercial communications satellite into a geosynchronous orbit that will keep it positioned above Asia—and represent the first… (arstechnica.com) さらに...Sort type: [Top] [Newest]
Great work! I'm impressed to see the Falcon 9 is powerful enough to get a satellite that far out in space. Normal geosync is out around 36,000KM. That's some rocket!!
The transfer orbit where the Falcon 9 dropped the satellite off was somewhere around 275km x 80500km. Orbit mechanics figured out that flying above GSO and having the spacecraft raise its perigee from there is actually more efficient than a straight Hohmann transfer to GSO altitude.

Thanks for the info, I can see that a long ellipse would be more practical and stable.
AWESOME!! Cant believe I missed the launch
Are rocket launches exempt from EPA?
Why are they putting an Orbital Sciences TV satellite over SE Asia? Who there would pay even $10 a month for TV service? Cable and Satellite TV in the US is $100 a month and subscribers are dropping like flies. Internet streaming of video on demand is the path to the future.
