In January 2006, NASA’s New Horizons spacecraft sped far from Earth as the fastest spacecraft actually released. Earlier this yr, New Horizons handed the halfway stage to its far-flung main target, the Pluto system. In March 2011, the craft will pass the orbit of Uranus and start the final long leg of its cruise – the almost billion-mile journey across the area involving Uranus and Neptune.

New Horizons will reach the Pluto system – more than three billion miles from household – on July 14, 2015, fifty decades to the day soon after NASA’s Mariner four mission inaugurated the close-up imaging with the planets with its Mars flyby. And inside the months and weeks adjoining the Pluto close method, New Horizons will reconnoiter the dwarf planet and its retinue of 3 recognized moons in greater detail than any previous first flyby of the planet by any spacecraft.
Soon after completing its duties at Pluto, New Horizons will fire its engines and change program to create the very first of what will ideally be two flybys of tiny (25- to 30-mile-wide) but historical Kuiper Belt objects (KBOs).

The exploration from the terra incognita from the Kuiper Belt and its most well-known planet will give crucial insights into the formation historical past of the large planets, the architecture of our solar method, the nature of comets, and even the manner by which Earth and Mars may have acquired h2o along with other unstable compounds. Moreover, New Horizons will reveal the nature of a brand new and populous class of planets – the ice dwarfs, which have never been explored in spite of fifty years of robotic surveys with the terrestrial and big planets. From the time New Horizons completes its mission in 2019 or 2020, it’ll have opened up our system’s third and most distant region to spacecraft exploration and, we hope, rewritten textbooks.
