About 154 seconds after launch, the main engine will cut off, followed by separation of the first stage about three seconds later.
The second-stage engine will ignite after another eight seconds. Half a minute into the second-stage burn, the payload fairing will be jettisoned, having done its job of protecting the Jason-3 satellite during the first three minutes of flight. The first cutoff of the second-stage engine will take place nine minutes after liftoff. At this point the Jason-3 spacecraft and Falcon 9 second stage will have entered a 46-minute coast phase.
The second-stage engine will ignite for its second burn about 55 minutes after launch. Once Jason-3 has reached the desired orbit, the rocket will separate from the spacecraft about half a minute later, nearly 56 minutes after liftoff.
