{ "item_title" : "How to Kill an Asteroid", "item_author" : [" Robin George Andrews", "Graham Mack", "Graham Mack "], "item_description" : "A gripping account of the city-killer asteroids that could threaten Earth and the race to build a planetary defense system. There are approximately 25,000 city killer asteroids in near-Earth orbit--and most are yet to be found. Small enough to evade detection, they are capable of large-scale destruction, and represent our greatest cosmic threat. But in September 2022, against all odds, NASA's Double Asteroid Redirection Test (DART) mission deliberately crashed a spacecraft into a carefully selected city killer, altering the asteroid's orbit and proving that we stand a chance against them. In How to Kill an Asteroid, award-winning science journalist Robin George Andrews--who was at DART mission control when it happened--reveals the development of the technology that made it possible, from spotting elusive asteroids and comets to figuring out their geologic defenses and orchestrating a deflection campaign. In a propulsive narrative that plays like a sci-fi thriller, Andrews tells the story of the planetary defense movement, and introduces the international team of scientists and engineers now working to protect Earth.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/9/79/822/830/9798228303171_b.jpg", "price_data" : { "retail_price" : "45.95", "online_price" : "45.95", "our_price" : "45.95", "club_price" : "45.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
