Book Details

Called "spellbinding" (Scientific American) and "thrilling...a future classic of popular science" (Publishers Weekly), 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 humankind’s most historic achievements are in the past, the most distant planetary exploration ever attempted not only succeeded 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 planning for New Horizons’ second act, the amazing January 1, 2019 flyby of Ultima Thule, another billion miles beyond Pluto. Told from the insider’s perspective of mission leader Dr. Alan Stern and others on New Horizons, 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.

In The News

“Stern and Grinspoon’s record of this epic project is thoroughly captivating… Suffused with serpentine theatrics and scientific wonder, this is a consistently compelling, top-notch documentation of intrepid planetary exploration.”

“Riveting… a fascinating David versus Goliath story… Even though we know the final outcome, the story continues to be a nail-biter… The two authors, with their insider’s perspective, capture the arduous process with great narrative verve.”
—Marcia Bartusiak, The Wall Street Journal

“A remarkable new book… told in exhilarating prose that moves this incredible narrative briskly without getting mired in the tall weeds of technical jargon…. Stern and Grinspoon take you on an uplifting, exhilarating, fascinating journey, all without leaving the comfort and oxygen of our planet.”
—Scott Stantis, Chicago Tribune

“An exhilarating trek into the ‘wild black yonder’.”
—Barbara Kiser, Nature

“A space and science book that reads more like a thriller.”

“Terrific new book about a terrific spacecraft flying a terrific mission! Kudos to Alan Stern, the man who gave us back Pluto.”
—Jeffrey Kluger (on Twitter, April 25, 2018)

“The two writers know their stuff: Stern is the principal investigator who led the New Horizon’s team to Pluto, and he is considered a veritable force of nature within the planetary science community. Grinspoon may well be the most talented science writer this side of his friend and mentor, the late Carl Sagan…. With an exciting narrative, loads of planetary astronomy, a heaping helping of exploration and discovery, and a happy ending, the book seems destined to be a classic.”
—Steven Andrew, Daily Kos

Chasing New Horizons, using a thriller-writer’s you-are-there narrative style, takes readers on the adventure of Alan Stern’s and his remarkable team’s lifetimes… Chasing New Horizons would be a ‘great read’ if it were fiction. But as a true story, it is impossible to resist. From the Preface to the ‘Final Discovery’ of the Coda and through the Top-Ten Science Discoveries list in the Appendix, this is a book for science readers to savor.”
—Fred Bortz, The Science Shelf

“A truly prodigious book by Alan Stern & David Grinspoon humankind's first voyage to Pluto. Strongly, even urgently recommended.”
—Homer Hickam, author of October Sky (on Twitter April 30, 2018)

—Jeff Foust, The Space Review

“I have read the book twice… It’s a thought-provoking and well-written story of the behind-the-scenes action that brought the spacecraft to life…. Chasing New Horizons presents a lot of insight into what it’s like to be on a spacecraft mission. Those revelations delighted me to no end…. The book belongs on your bookshelf. Read it often. Appreciate what it is our fellow citizens have done to bring Pluto and the Kuiper Belt into our view.”
—C.C. Petersen,

“A page-turner.”
—Randy Showstack,

“[Chasing New Horizons] delivers an in-depth view of how to design a space mission, shepherd it through the hurdles of approval and design, and send it toward the unknown when you have just one shot to get it right.”
—Sarah Lewin,

—Astronomy Magazine Podcast

“Even if you followed the [Pluto] flyby closely and think you know this story, the book divulges details that will surprise you. Come for the sweeping tale of wonder and exploration; stay for the gaggle of planetary scientists celebrating on Bourbon Street once their mission finally got the green light.”
