   New Horizons Becomes Closest Spacecraft to Approach Pluto   
       
   Dec 3, 2011:  NASA's New Horizons mission reached a special milestone   
   yesterday, Dec. 2, 2011, on its way to reconnoiter the Pluto system, coming   
   closer to Pluto than any other spacecraft.   
       
   It's taken New Horizons 2,143 days of high-speed flight - covering more than a   
   million kilometers per day for nearly six years-to break the closest-approach   
   mark of 1.58 billion kilometers set by NASA's Voyager 1 in January 1986.

   Click on the image to view the current position of New Horizons as it races   
   toward Pluto.   
   "What a cool milestone!" says New Horizons Principal Investigator Alan Stern,   
   of the Southwest Research Institute. "Although we're still a long way - 1.5   
   billion kilometers from Pluto - we're now in new territory as the closest any   
   spacecraft has ever gotten to Pluto, and getting closer every day by over a   
   million kilometers.   
       
   Now New Horizons, which is healthy, on course and closer to Pluto than Voyager   
   ever came, will continue to set proximity-to-Pluto records every day until its   
   closest approach - about 7,767 miles (12,500 kilometers) from the planet - on   
   July 14, 2015.

   New Horizons' current view of Pluto still resembles this image snapped by the   
   spacecraft's long-range telescopic camera in 2007; that will change   
   exponentially beginning in late 2014, as New Horizons speeds closer to its   
   target planet and its cameras begin to resolve details. "We've come a long way   
   across the solar system," says Glen Fountain, New Horizons project manager at   
   the Johns Hopkins University Applied Physics Laboratory. "When we launched [on   
   Jan. 19, 2006] it seemed like our 10-year journey would take forever, but   
   those years have been passing us quickly. We're almost six years in flight,   
   and it's just about three years until our encounter begins."   
       
   From New Horizons' current distance to Pluto - about as far as Earth is from   
   Saturn - Pluto remains just a faint point of light. But by the time New   
   Horizons sails through the Pluto system in mid-2015, the planet and its moons   
   will be so close that the spacecraft's cameras will spot features as small as   
   a football field.   
       
   "I wonder how long it will be until the next Pluto spacecraft - perhaps a   
   future orbiter or lander - crosses this distance marker?" Stern continues. "It   
   could be decades."   
       
   New Horizons is currently in hibernation, with all but its most essential   
   systems turned off, speeding away from the Sun at more than 55,500 kilometers   
   per hour. Operators at the Applied Physics Lab will "wake" the spacecraft in   
   January for a month of testing and maintenance activities.
