The 229-foot-tall (70-meter) rocket took off at 12:45 a.m. EDT (0445 GMT) Monday from Cape Canaveral's Complex 40 launch pad, and headed east over the Atlantic Ocean. For example, the company has launched pre-flown Dragon capsules on robotic cargo missions to the International Space Station, and two of the three Falcon 9 first stages that form the core of SpaceX's Falcon Heavy rocket landed successfully during the huge launcher's debut flight in February.
SES was the first company to fly a spacecraft on a used Falcon 9 rocket booster. SpaceX may try to recover the Falcon 9 fairings at sea, which make up the rocket's nose cone, where the payload is encased.
SpaceX won't land the booster again.
This is actually confirmation of something we already more-or-less knew.
The rocket will carry the SES-12 satellite to orbit for the Luxembourg-based telecom company SES. The satellite will be deployed roughly 32 minutes after liftoff. It is created to support SES's direct-to-home broadcasting and data connectivity services in the Middle East and the Asia-Pacific region, including rapidly growing markets such as India and Indonesia, according to SES.
