New Horizons was designed by NASA to study Pluto and the fringes of our solar system, farther away than any spacecraft has ever explored. Join science writer Elaine Scott as she tells the story of this mission. For Stephen Hawking, New Horizons signifies that "We explore because we are human and we want to know." This remarkable ship, no bigger than a piano, and using no more energy than a lightbulb, has already traveled three billion miles out to Pluto, and is continuing on to the Kuiper Belt, the farthest reaches of our solar system. The book will feature the beautiful, amazingly sharp photographs it is sending back from its journey, which are letting scientists fill in the blanks in our knowledge of Pluto--and delivering a few surprises along the way. Elaine Scott tells the exciting story of everyone's favorite planet, from Pluto's discovery through the frustrating attempts to study such a distant object, the creation of the New Horizons project, scientists' hopes and expectations for the mission, and what is being discovered. Her clear, engaging prose does more than narrate the events. By showing how scientists operate, their hypotheses, hopes, and disappointments, and how they make use of them, she gives readers an inspiring portrait of the scientific method itself.

In the ten years preceding publication, the known solar system more than doubled in size. For the first time in almost two centuries an entirely new population of planetary objects was found. This 'Kuiper Belt' of minor planets beyond Neptune revolutionised our understanding of the solar system's formation and finally explained the origin of the enigmatic outer planet Pluto. This is the fascinating story of how theoretical physicists decided that there must be a population of unknown bodies beyond Neptune and how a small band of astronomers set out to find them. What they discovered was a family of ancient planetesimals whose orbits and physical properties were far more complicated than anyone expected. We follow the story of this discovery, and see how astronomers, theoretical physicists and one incredibly dedicated amateur observer came together to explore the frozen boundary of the solar system.

Called "spellbinding" (Scientific American) and "thrilling...a future classic of popular science" (PW), the up close, inside story of the greatest space exploration project of our time, New Horizons’ mission to Pluto, as shared with David Grinspoon by mission leader Alan Stern and other key players. On July 14, 2015, something amazing happened. More than 3 billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long mysterious icy worlds of the Pluto system, and then, just as quickly, continued on its journey out into the beyond. Nothing like this has occurred in a generation—a raw exploration of new worlds unparalleled since NASA’s Voyager missions to Uranus and Neptune—and nothing quite like it is planned to happen ever again. The photos that New Horizons sent back to Earth graced the front pages of newspapers on all 7 continents, and NASA’s website for the mission received more than 2 billion hits in the days surrounding the flyby. At a time when so many think that our most historic achievements are in the past, the most distant planetary exploration ever attempted not only succeeded in 2015 but made history and captured the world’s imagination. How did this happen? Chasing New Horizons is the story of the men and women behind this amazing mission: of their decades-long commitment and persistence; of the political fights within and outside of NASA; of the sheer human ingenuity it took to design, build, and fly the mission; and of the plans for New Horizons’ next encounter, 1 billion miles past Pluto in 2019. Told from the insider’s perspective of mission leader Dr. Alan Stern and others on New Horizons, and including two stunning 16-page full-color inserts of images, Chasing New Horizons is a riveting account of scientific discovery, and of how much we humans can achieve when people focused on a dream work together toward their incredible goal.

Once perceived as distant, cold, dark, and seemingly unknowable, Pluto had long been marked as the farthest and most unreachable frontier for solar system exploration. The Pluto System After New Horizons is the benchmark research compendium for synthesizing our understanding of the Pluto system. This volume reviews the work of researchers who have spent the last five years assimilating the data returned from New Horizons and the first full scientific synthesis of this fascinating system.

Discovering Pluto is an authoritative account of the exploration of Pluto and its moons, from the first inklings of tentative knowledge through the exciting discoveries made during the flyby of the NASA New Horizons research spacecraft in July 2015. Co-author Dale P. Cruikshank was a co-investigator on the New Horizons mission, while co-author William Sheehan is a noted historian of the Solar System. Telling the tale of Pluto’s discovery, the authors recount the grand story of our unfolding knowledge of the outer Solar System, from William Herschel’s serendipitous discovery of Uranus in 1781, to the mathematical prediction of Neptune’s existence, to Percival Lowell’s studies of the wayward motions of those giant planets leading to his prediction of another world farther out. Lowell’s efforts led to Clyde Tombaugh’s heroic search and discovery of Pluto—then a mere speck in the telescope—at Lowell Observatory in 1930. Pluto was finally recognized as the premier body in the Kuiper Belt, the so-called third zone of our Solar System. The first zone contains the terrestrial planets (Mercury through Mars) and the asteroid belt; the second, the gas-giant planets Jupiter through Neptune. The third zone, holding Pluto and the rest of the Kuiper Belt, is the largest and most populous region of the solar system. Now well beyond Pluto, New Horizons will continue to wend its lonely way through the galaxy, but it is still transmitting data, even today. Its ultimate legacy may be to inspire future generations to uncover more secrets of Pluto, the Solar System, and the Universe.

This is a book about living with Alzheimer’s, not dying with it. It is a book about hope, faith, and humor—a prescription far more powerful than the conventional medication available today to fight this disease. Alzheimer’s is the sixth leading cause of death in the US—and the only one of these diseases on the rise. More than 5 million Americans have been diagnosed with Alzheimer’s or a related dementia; about 35 million people worldwide. Greg O’Brien, an award-winning investigative reporter, has been diagnosed with early-onset Alzheimer's and is one of those faceless numbers. Acting on long-term memory and skill coupled with well-developed journalistic grit, O’Brien decided to tackle the disease and his imminent decline by writing frankly about the journey. O’Brien is a master storyteller. His story is naked, wrenching, and soul searching for a generation and their loved ones about to cross the threshold of this death in slow motion. On Pluto: Inside the Mind of Alzheimer’s is a trail-blazing roadmap for a generation—both a “how to” for fighting a disease, and a “how not” to give up!

Space and planets are topics of endless fascination to kids and part of every grade-school curriculum. Yet because of the history-making reassignment of Pluto from "planet” to "dwarf planet” on August 24, 2006, all books on the solar system are now out of date. Enter When is a Planet Not a Planet? The Story of Pluto by Elaine Scott, an esteemed writer of non-fiction for children. Scott is the first to put the answer to the title question into terms simple enough for a very young audience to understand, based upon the new definitions determined by the International Astronomical Union. Well-researched and accompanied by large, awe-inspiring photographs and paintings, this exciting new book makes clear what astronomers have argued about for decades.
