New Horizons may have to dodge debris at Pluto

New Horizons may face hazardous debris ball at Pluto: "NASA's New Horizons mission may encounter tumultuous clouds of ice and rock when it flies by Pluto in 2015, and engineers are prepared move the spacecraft on an alternate course by the dwarf planet to spare the probe from fatal debris strikes, officials said Tuesday.

"This is our first time to the Kuiper Belt, the very frontier of our planetary system," said Alan Stern, the New Horizon principal investigator from the Southwest Research Institute in Boulder, Colo."
