    Mission Overview: Why Go to Pluto ? Planetary exploration is a historic endeavor and a major focus of NASA. New Horizons is designed to help us understand worlds at the edge of our solar system by making the first reconnaissance of Pluto and Charon - a "double planet" and the last planet in our solar system to be visited by spacecraft. Then, as part of an extended mission, New Horizons would visit one or more objects in the Kuiper Belt region beyond Neptune.

    Science at the Frontier

    Our solar system contains three zones: the inner, rocky planets; the gas giant planets; and the Kuiper Belt. Pluto is one of the largest bodies of the icy, "third zone" of our solar system. The National Academy of Sciences placed the exploration of the third zone in general - and Pluto-Charon in particular - among its highest priority planetary mission rankings for this decade. New Horizons is NASA's mission to fulfill this objective.

    In those zones, our solar system has three classes of planets: the rocky worlds (Earth, Venus, Mercury and Mars); the gas giants (Jupiter, Saturn, Uranus and Neptune); and the ice dwarfs of the Kuiper Belt. There are far more ice dwarf planets than rocky and gas giant worlds combined - yet, no spacecraft has been sent to a planet in this class. The National Academy of Sciences noted that our knowledge of planetary types is therefore seriously incomplete. As the first mission to investigate this new class of planetary bodies, New Horizons will fill this important gap and round out our knowledge of the planets in our solar system.


    Ancient Relics

    The ice dwarfs are planetary embryos, whose growth stopped at sizes (200 to 2,000 kilometers across) much smaller than the full-grown planets in the inner solar system and the gas giants region. The ice dwarfs are ancient relics that formed over 4 billion years ago. Because they are literally the bodies out of which the larger planets accumulated, the ice dwarfs have a great deal to teach us about planetary formation. New Horizons seeks those answers.


    Binary Planet

    Pluto's largest moon, Charon, is half the size of Pluto. The pair form a binary planet, whose gravitational balance point is between the two bodies. Although binary planets are thought to be common in the galaxy, as are binary stars, no spacecraft has yet explored one. New Horizons will be the first mission to a binary object of any type.


    A Mission with Impact

    The Kuiper Belt is the major source of cometary impactors on Earth, like the impactor that wiped out the dinosaurs. New Horizons will shed new light on the number of such Kuiper Belt impactors as a function of their size by cataloging the various-sized craters on Pluto, its moons, and on Kuiper Belt Objects.

    Pluto and the Kuiper Belt are known to be heavily endowed with organic (carbon-bearing) molecules and water ice — the raw materials out of which life evolves. New Horizons will explore the composition of this material on the surfaces of Pluto, its moons and Kuiper Belt Objects.


    The Great Escape

    Pluto's atmosphere is escaping to space like a comet, but on a planetary scale. Nothing like this exists anywhere else in the solar system. It is thought that the Earth's original hydrogen/helium atmosphere was lost to space this way. By studying Pluto's atmospheric escape, we can learn a great deal about the evolution of Earth's atmosphere. New Horizons will determine Pluto's atmospheric structure and composition and directly measure its escape rate for the first time.


    The Need to Explore

    As the first voyage to a whole new class of planets in the farthest zone of the solar system, New Horizons is a historic mission of exploration. The United States has made history by being the first nation to reach every planet from Mercury to Neptune with a space probe. The New Horizons mission to Pluto and the Kuiper Belt - the first NASA launch to a "new" planet since Voyager more than 30 years ago - allows the U.S. to complete the reconnaissance of the solar system.

    Pluto 'Up-Close' Coming Soon: Spacecraft's Historic Encounter

    Published on Jan 14, 2014

    NASA's New Horizon spacecraft left Earth in 2006 and is quickly approaching its fly-by of the icy dwarf planet and its moons. Its closest approach will occur on July 14th, 2015.

    NASA's New Horizons Spacecraft: Getting to Pluto

    Published on Apr 14, 2015

    In NASA'a second televised briefings on Tuesday, April 14, plans and upcoming activities about the agency’s mission to Pluto that will make the first-ever close flyby of the dwarf planet on July 14 were briefed.

    Briefers described the mission’s goals and context, scientific objectives and encounter plans – including what images can be expected and when.

    New Horizons already has covered more than 3 billion miles since it launched on Jan. 19, 2006. The spacecraft will pass Pluto at a speed of 31,000 mph taking thousands of images and making a wide range of science observations. At a distance of nearly 4 billion miles from Earth at flyby, it will take approximately 4.5 hours for data to reach Earth.

    Participants for the 2:20-3:30 p.m. discussion were:

    - James Green, director of Planetary Science, NASA Headquarters
    - Glen Fountain, New Horizons Project Manager, Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland
    - Hal Weaver, New Horizons Project Scientist, Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland
    - Alan Stern, New Horizons Principal Investigator, Southwest Research Institute, Boulder, Colorado

    The Year of Pluto - NASA New Horizons

    Published on Jun 10, 2015

    The New Horizons mission will help us understand worlds at the edge of our solar system by making the first reconnaissance of the dwarf planet Pluto and by venturing deeper into the distant, mysterious Kuiper Belt – a relic of solar system formation.

    Pluto is 'Beige-Orange' In New Pixelated New Horizons Images

    Published on Jun 19, 2015

    In new imagery of the dwarf planet taken from May 29th to June 3rd, 2015, its "near-true color" is revealed. Charon, also in view, is grey. The images are presented in a 'barycentric view,' with both Pluto and Charon in motion, and a 'Pluto-centric' view, where the icy dwarf is kept mid-screen.

    6 30 15 Pluto movie annotated NASA JHUAPL SWRI

    Published on Jun 30, 2015

    This movie, from New Horizons’ highest-resolution imager, shows Pluto and Charon as the spacecraft closes in. In the annotated version, Pluto’s prime meridian (the region of the planet that faces Charon) is shown in yellow and the equator is shown in pink.

    Pluto and Charon in first color movie

    Published on Jul 3, 2015

    This is the first movie to reveal color surface features of Pluto and its moon Charon. The images were taken by NASA's New Horizons between June 23 and June 29, 2015, from a distance of 24 million to 18 million kilometers (15 million to 11 million miles). Also, some images of Pluto seen through the ages.
