KENNEDY SPACE CENTER, FLA. - The Atlas V rocket with the New Horizons spacecraft on top sits waiting on the launch pad at Complex 41 at Cape Canaveral Air Force Station in Florida. The view is from the top of the Vehicle Assembly Building at NASA Kennedy Space Center. Surrounding the launch vehicle are four lightning masts. The launch on this date was scrubbed due to high surface winds in the area and has been rescheduled for 1:16 p.m. EST Jan. 18. The compact, 1,050-pound piano-sized probe will get a boost from a kick-stage solid propellant motor for its journey to Pluto. New Horizons will be the fastest spacecraft ever launched, reaching lunar orbit distance in just nine hours and passing Jupiter 13 months later. The launch at this time allows New Horizons to fly past Jupiter in early 2007 and use the planet’s gravity as a slingshot toward Pluto. The Jupiter flyby trims the trip to Pluto by as many as five years and provides opportunities to test the spacecraft’s instruments and flyby capabilities on the Jupiter system. New Horizons could reach the Pluto system as early as mid-2015, conducting a five-month-long study possible only from the close-up vantage of a spacecraft. Photo credit: NASA/Kim Shiflett
