CRASHING INTO BOOKSTORES WORLDWIDE

It’s 7pm on September 26th, 2022. Across the campus of a university in Maryland, hundreds of people are glued to their screens—windows into the cold depths of space—counting down to the moment that everything changes. And all over the world, astronomers are standing by their telescopes, all pointed at one tiny speck of light in the night sky. Seven million miles from home, an uncrewed spaceship is heading toward an asteroid at breakneck speeds. Its mission: to crash straight into it, losing its robotic life in the process and change the journey of that asteroid around the sun.

This is it. This single space mission could alter the course of human history.

Forget the planet killers; astronomers have found pretty much all the heftiest asteroids. But tens of thousands of so-called city killers – asteroids the size of football stadiums – lurk out there in the darkness, as yet undiscovered. They are far more likely to impact Earth than those rarer, larger rocky beasts. They have struck Earth plenty of times in the past. More impacts are a certainty. And if we get unlucky, one could careen into a random country with little warning, killing millions of people in an instant.

For most of our species’ existence, we were helpless to stop such a catastrophe. But perhaps no longer: If all goes according to plan, in the not-too-distant future, we will be able to prevent any of those elusive city killer asteroids from ever reaching our planet, making this the only natural disaster we can completely prevent. And it all starts with something as brilliant as it is absurd: build a spacecraft like none other, find an asteroid, slam into it as fast as possible, and deflect it—a trial run for saving a city, a country, or even the world.

Voyaging across the world, from America to Japan, from Botswana to Russia, before journeying millions of miles through space, HOW TO KILL AN ASTEROID tells the propulsive true story of how a maverick team of madcap scientists and eccentric engineers plan to prevent an inevitable future asteroid impact by creating Earth’s planetary defense system—one that ultimately hinges on whether humanity’s very first attempt to dramatically deflect an asteroid succeeds or fails. And it only took a prison break, Oppenheimer, a small city in North Carolina volunteering to be hit by an asteroid, two robots stealing cosmic matter from the dawn of time, blowing up cotton candy with a very big gun, several exploding alien intruders, a planet killer comet striking Jupiter, priceless extraterrestrial material being hidden in a British shopping bag, a spy inside the sun’s vast shadow, a giant hole in the middle of Arizona, a small Italian box in deep space, Star Wars, Star Trek, a wild idea by someone in the U.S. Air Force, and a heck of a lot of people looking up, to get there.

It is a story of triumph and innovation, of creative design and engineering genius, a science-(non)fiction thriller about averting the end of the world as we know it.

“Deeply researched and tenaciously reported, How to Kill an Asteroid is a detailed inside look at some of the most important recent undertakings in the history of space science. In this comprehensive chronicle, Andrews tells nothing less than the story of humanity’s effort to, as one of his sources puts it, ‘rearrange the solar system’ in order to save the world. A scientist turned journalist, Andrews is a spirited, erudite, and humorous guide, delivering prose that is scholarly yet conversational, grounded yet cinematic. For space enthusiasts, this fascinating book will surely be as much a valuable resource as a heaping bowl of mind candy.”

—Ferris Jabr, author of Becoming Earth: How Our Planet Came to Life

“How to Kill an Asteroid is a testament to humanity’s ingenuity in the face of cosmic danger, and you will not find a more enthusiastic and skilled planetary guide than Andrews. With riveting detail and cinematic flair, the book catapults readers into a reality that feels like science fiction. Andrews gives readers a front-row seat to the drama of destruction and self-preservation, and reminds us that even in the face of danger, there's room for wit and humor. As Andrews quips, ‘who says you can’t have fun while trying to to save the world?’”

—Kristy Hamilton, science journalist and award-winning author of Nature's Wild Ideas

“Andrews’ writing style is funny, wry, passionate, and deeply informed. How To Kill An Asteroid is one of the most entertaining pop-science reads of the year.”

—John Keogh, Booklist (Starred Review)

“This vividly written book…reads as much like a thriller as the film plots it is trying to correct… From the first page, Andrews throws us into the action... The language is beautifully chosen, and the future leaps into life through his words. Andrews’s dexterity in explaining complicated concepts, including how to knock asteroids off-orbit, makes this book well worth picking up, but that verbal vivacity is matched by deep reporting. One chapter… is hauntingly written. But there is positivity too, as we realise the brightest minds are working to protect us from doomsday.”

“You will finish the book as informed as you are entertained.”

—Chris Stokel-Walker, New Scientist

“How to Kill an Asteroid by science journalist Robin George Andrews is a deep dive into the extremely badass business of thwarting a destructive asteroid… Andrews does an admirable job of packing in details and context about the field. His thorough research brings readers all over the world and across time… Andrews frames DART’s tale as a gripping disaster thriller: An asteroid is hypothetically hell-bent on destroying Earth, and it’s up to scientist superheroes to save the world. Though full of suspense, the writing is also at times witty and lighthearted.”

—Shi En Kim, Science News

”Acclaimed science journalist Robin George Andrews offers a sometimes scary, often humorous and always erudite account of the people and projects striving to safeguard Earth from space rocks and help humanity avoid the dinosaurs’ dismal fate.”
—Lee Billings, Scientific American

“Andrews serves up a rollicking study of scientific efforts to prevent asteroids from striking Earth… [and] offers a tense firsthand account of what it was like inside Johns Hopkins University’s Applied Physics Laboratory… during the countdown to impact. Andrews’s sharp eye for detail captures the expertise and eccentricity of scientists involved in the DART mission… It’s a surprisingly fun report on averting catastrophe.”

—Publishers Weekly

”Award-winning science journalist Robin Andrews offers a rare personal look at the development of the mission, the team that made it happen, and what it was like to be inside the mission control room when the asteroid got smacked. The book leans into the sci-fi fantasy aspect of the mission, detailing all the cool science while still delivering drama, humor, and a great group of characters.”
—Passant Rabie, Gizmodo
