As the spacecraft approaches, early images show Pluto and Charon coming into focus as little spheres. We can see the first hints of surface features. Four tiny moons, apart from Charon, have emerged from the planet's glare. As the craft gets even closer, will we discover previously unknown moons? I'd guess yes, but it might take a while to know: Though the New Horizons flyby will be over in an instant, the spacecraft speeding on toward interstellar space, the images will dribble back over many months.
