SpaceX Falcon 9 launched from Cape Canaveral this afternoon, in a picture-perfect liftoff. The vehicle separation occurred as planned, and shortly after that, the second stage ignited as designed. Beautiful!
In its first attempt at launch earlier today, Falcon 9 remained on its launch pad at Cape Canaveral because of an engine abort with about a second before liftoff. After that happened, SpaceX said the spacecraft put itself into "safe mode."
A few minutes later, SpaceX reported, "The pad abort involved an out-of-limit startup parameter." About an hour later, the countdown was resumed, and the powerful two-stage rocket gracefully lifted off the launch pad. At 9 minutes,4 seconds after launch, Falcon 9 achieved Earth orbit.
