A successful launch, sans nuclear meltdown.
link, with video. Don't blink that thing's outta there, well, like a rocket. Maybe I'm just seeing what I want to see, but it seems to me that the speed difference between this launch and a shuttle launch is readily apparant (though I would presume the speed difference between this and other un-manned launches is lesser).
On an overall mission note, NASA's trying to decide whether they want to alter the flight plan slightly to include some observation of the 2 newly discovered moons around Pluto. They'd better hurry, they only have 10 years to decide.
