The first color photo of Pluto showed up last week, smudgy from a distance of 71 million miles. Expect a more exciting show when New Horizons arrives on the scene with its cameras, spectrometers and plasma and dust detectors, getting as close as 7,750 miles from Pluto's surface. Some spectacular pictures should show up quickly, but it will take more than a year for New Horizons to transmit everything it records back to Earth. That will allow the spacecraft to devote most of its attention to gathering more data.
