NASA's New Horizons is speeding towards the edge of our solar system for a July 14, 2015 flyby of Pluto. At its closest approach the spacecraft will be zipping by at about 7800 miles (12,500 kilometers) above the surface. It's the first mission to Pluto and the Kuiper Belt and it won't be making observations alone. NASA's fleet of observatories will also be busy gathering data before and after to help piece together what we know about Pluto. Sending this spacecraft on an almost 3 billion mile journey will help answer basic questions about the surface properties, atmospheres, and moons of the Pluto system.
