Gene Cernan, the last man to walk on the moon, departed from the lunar surface on December 14, 1972. The last words he spoke, officially, were, "And, as we leave the Moon at Taurus-Littrow, we leave as we came and, God willing, as we shall return: with peace and hope for all mankind. Godspeed the crew of Apollo 17." Decades later, despite the efforts of two American presidents, human beings have not returned to the moon. Why Earth's nearest neighbor remains untouched by human footsteps after so long remains one of the vexing questions of modern times. Mark R. Whittington, the author of the Children of Apollo trilogy and The Last Moonwalker and Other Stories, attempts to answer this question in his new long essay Why is it so Hard to Go Back to the Moon? The answer involves failures of leadership of multiple American presidents as well as political intrigue and backstabbing that shortened the Apollo program and left two return to the Moon programs stillborn. More important, Whittington seeks to set out a political blue print, learning from mistakes of the past, for setting course back to the Moon. Why is it so Hard to Go Back to the Moon is not a typical future in space book. The author does not delve into technical designs for lunar voyages. Instead he looks at the much harder than rocket science art of politics in relation to returning to the Moon. Why is it so Hard to Go Back to the Moon? is a must read for anyone interested in influencing future space policy or who are just interested in learning about the intersection between space exploration and politics.

"Pop-Up book for kids about the historic Apollo 11 landing, on its 50th anniversary."--

Radiating fire and ice, comets as a phenomenon seem part science, part myth. Two thousand years ago when a comet shot across the night sky, it convinced the Romans that Julius Caesar was a god. In 1066, Halley’s Comet was interpreted as a foreshadowing of the death of Harold the Second in the Battle of Hastings. Even today the arrival of a comet often feels auspicious, confirming our hopes, fears, and sense of wonder in the universe. In Comets, P. Andrew Karam takes the reader on a far-ranging exploration of these most beautiful and dramatic objects in the skies, revealing how comets and humanity have been interwoven throughout history. He delves into the science of comets and how it has changed over time; the way comets have been depicted in art, religion, literature, and popular culture; and how comets have appeared in the heavens through the centuries. Comprehensive in scope and beautifully illustrated throughout, the book will appeal not only to the budding astronomer, but to anyone with an appreciation for these compelling and remarkable celestial bodies.

The New York Times bestselling, “meticulously researched and absorbingly written” (The Washington Post) story of the trailblazers and the ordinary Americans on the front lines of the epic Apollo 11 moon mission. President John F. Kennedy astonished the world on May 25, 1961, when he announced to Congress that the United States should land a man on the Moon by 1970. No group was more surprised than the scientists and engineers at NASA, who suddenly had less than a decade to invent space travel. When Kennedy announced that goal, no one knew how to navigate to the Moon. No one knew how to build a rocket big enough to reach the Moon, or how to build a computer small enough (and powerful enough) to fly a spaceship there. No one knew what the surface of the Moon was like, or what astronauts could eat as they flew there. On the day of Kennedy’s historic speech, America had a total of fifteen minutes of spaceflight experience—with just five of those minutes outside the atmosphere. Russian dogs had more time in space than US astronauts. Over the next decade, more than 400,000 scientists, engineers, and factory workers would send twenty-four astronauts to the Moon. Each hour of space flight would require one million hours of work back on Earth to get America to the Moon on July 20, 1969. “A veteran space reporter with a vibrant touch—nearly every sentence has a fact, an insight, a colorful quote or part of a piquant anecdote” (The Wall Street Journal) and in One Giant Leap, Fishman has written the sweeping, definitive behind-the-scenes account of the furious race to complete one of mankind’s greatest achievements. It’s a story filled with surprises—from the item the astronauts almost forgot to take with them (the American flag), to the extraordinary impact Apollo would have back on Earth, and on the way we live today. From the research labs of MIT, where the eccentric and legendary pioneer Charles Draper created the tools to fly the Apollo spaceships, to the factories where dozens of women sewed spacesuits, parachutes, and even computer hardware by hand, Fishman captures the exceptional feats of these ordinary Americans. “It’s been 50 years since Neil Armstrong took that one small step. Fishman explains in dazzling form just how unbelievable it actually was” (Newsweek).

From the #1 New York Times bestselling author of Anathem, Reamde, and Cryptonomicon comes an exciting and thought-provoking science fiction epic—a grand story of annihilation and survival spanning five thousand years. What would happen if the world were ending? A catastrophic event renders the earth a ticking time bomb. In a feverish race against the inevitable, nations around the globe band together to devise an ambitious plan to ensure the survival of humanity far beyond our atmosphere, in outer space. But the complexities and unpredictability of human nature coupled with unforeseen challenges and dangers threaten the intrepid pioneers, until only a handful of survivors remain . . . Five thousand years later, their progeny—seven distinct races now three billion strong—embark on yet another audacious journey into the unknown . . . to an alien world utterly transformed by cataclysm and time: Earth. A writer of dazzling genius and imaginative vision, Neal Stephenson combines science, philosophy, technology, psychology, and literature in a magnificent work of speculative fiction that offers a portrait of a future that is both extraordinary and eerily recognizable. As he did in Anathem, Cryptonomicon, the Baroque Cycle, and Reamde, Stephenson explores some of our biggest ideas and perplexing challenges in a breathtaking saga that is daring, engrossing, and altogether brilliant.

Former NASA Astronaut Harrison Schmitt advocates a private, investor-based approach to returning humans to the Moon—to extract Helium 3 for energy production, to use the Moon as a platform for science and manufacturing, and to establish permanent human colonies there in a kind of stepping stone community on the way to deeper space. With governments playing a supporting role—just as they have in the development of modern commercial aeronautics and agricultural production—Schmitt believes that a fundamentally private enterprise is the only type of organization capable of sustaining such an effort and, eventually, even making it pay off.
