In July of 2015, a robotic spacecraft reached Pluto after a nine-and-a-half-year journey. Explore with New Horizons in this new-to-paperback book about the first mission to Pluto, which revealed the ice dwarf and its five moons as they had never been seen before. Images from the mission show a reddish surface covered in mountains of frozen water, moving glaciers, hints of possible ice volcanoes, and an underground ocean. Pluto is geologically alive and changing! This addition to the Scientists in the Field series goes where no person or spacecraft has ever gone before. Journey with the team of scientists as they build New Horizons, fly it across the solar system, and make new discoveries about a world three billion miles away.
