Since the dawn of the Space Age, small cohorts of humanity have broadcast signals towards other stars, fabricated "space-time capsules" to "speak for Earth" aboard interstellar probes, deposited collections of "space oddities" on other astronomical bodies, and permanently incised the memory of our species across the deep-time legacy of the Sol System. Many of these purposeful "messages" are the consequence of age-old behaviors, traditions, and material practices using modern aerospace technologies. Most attempt to preserve narratives of human experience in social exchange devices for imagined, exotic audiences. Looking back upon this accumulative history of "messaging from Earth", how do we begin to interpret such an eclectic portrait of Earth for ourselves? Surveying and cataloguing the variety of these artifacts through a series of interdisciplinary essays and visual documentation, this volume chronicles our changing relationships, customs, and assumptions made within this material culture for our own eyes. What do these autobiographical accounts tell us about Terrans and our minds, set against the backdrop of our planetary history?

We are at the cusp of a golden age in space science, as increasingly more entrepreneurs—Elon Musk, Richard Branson, Jeff Bezos—are seduced by the commercial potential of human access to space. But Beyond Earth does not offer another wide-eyed technology fantasy: instead, it is grounded not only in the human capacity for invention and the appeal of adventure, but also in the bureaucratic, political, and scientific realities that present obstacles to space travel—realities that have hampered NASA's efforts ever since the Challenger disaster. In Beyond Earth, the authors offer groundbreaking research and argue persuasively that not Mars, but Titan—a moon of Saturn with a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy—offers the most realistic, and thrilling, prospect of life without support from Earth.

Current state of play in astrobiology, including exoplanets and their atmospheres, habitable zones and the likelihood of evolution elsewhere.

As command module pilot for the Apollo 15 mission to the moon in 1971, Al Worden flew on what is widely regarded as the greatest exploration mission that humans have ever attempted. He spent six days orbiting the moon, including three days completely alone, the most isolated human in existence. During the return from the moon to earth he also conducted the first spacewalk in deep space, becoming the first human ever to see both the entire earth and moon simply by turning his head. The Apollo 15 flight capped an already-impressive career as an astronaut, including important work on the pioneering Apollo 9 and Apollo 12 missions, as well as the perilous flight of Apollo 13. Nine months after his return from the moon, Worden received a phone call telling him he was fired and ordering him out of his office by the end of the week. He refused to leave. What happened in those nine months, from being honored with parades and meetings with world leaders to being unceremoniously fired, has been a source of much speculation for four decades. Worden has never before told the full story around the dramatic events that shook NASA and ended his spaceflight career. Readers will learn them here for the first time, along with the exhilarating account of what it is like to journey to the moon and back. It's an unprecedentedly candid account of what it was like to be an Apollo astronaut, with all its glory but also its pitfalls.

Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

The Instant New York Times Bestseller! Was an advanced civilization lost to history in the global cataclysm that ended the last Ice Age? Graham Hancock, the internationally bestselling author, has made it his life's work to find out--and in America Before, he draws on the latest archaeological and DNA evidence to bring his quest to a stunning conclusion. We’ve been taught that North and South America were empty of humans until around 13,000 years ago – amongst the last great landmasses on earth to have been settled by our ancestors. But new discoveries have radically reshaped this long-established picture and we know now that the Americas were first peopled more than 130,000 years ago – many tens of thousands of years before human settlements became established elsewhere. Hancock's research takes us on a series of journeys and encounters with the scientists responsible for the recent extraordinary breakthroughs. In the process, from the Mississippi Valley to the Amazon rainforest, he reveals that ancient "New World" cultures share a legacy of advanced scientific knowledge and sophisticated spiritual beliefs with supposedly unconnected "Old World" cultures. Have archaeologists focused for too long only on the "Old World" in their search for the origins of civilization while failing to consider the revolutionary possibility that those origins might in fact be found in the "New World"? America Before: The Key to Earth's Lost Civilization is the culmination of everything that millions of readers have loved in Hancock's body of work over the past decades, namely a mind-dilating exploration of the mysteries of the past, amazing archaeological discoveries and profound implications for how we lead our lives today.

Seeking to reenergize Americans' passion for the space program, the value of further exploration of the Moon, and the importance of human beings on the final frontier, Claude A. Piantadosi presents a rich history of American space exploration and its major achievements. He emphasizes the importance of reclaiming national command of our manned program and continuing our unmanned space missions, and he stresses the many adventures that still await us in the unfolding universe. Acknowledging space exploration's practical and financial obstacles, Piantadosi challenges us to revitalize American leadership in space exploration in order to reap its scientific bounty. Piantadosi explains why space exploration, a captivating story of ambition, invention, and discovery, is also increasingly difficult and why space experts always seem to disagree. He argues that the future of the space program requires merging the practicalities of exploration with the constraints of human biology. Space science deals with the unknown, and the margin (and budget) for error is small. Lethal near-vacuum conditions, deadly cosmic radiation, microgravity, vast distances, and highly scattered resources remain immense physical problems. To forge ahead, America needs to develop affordable space transportation and flexible exploration strategies based in sound science. Piantadosi closes with suggestions for accomplishing these goals, combining his healthy skepticism as a scientist with an unshakable belief in space's untapped—and wholly worthwhile—potential.

Should we believe in God? In this brisk introduction to modern atheism, one of the world’s greatest science writers tells us why we shouldn’t. Richard Dawkins was fifteen when he stopped believing in God. Deeply impressed by the beauty and complexity of living things, he’d felt certain they must have had a designer. Learning about evolution changed his mind. Now one of the world’s best and bestselling science communicators, Dawkins has given readers, young and old, the same opportunity to rethink the big questions. In twelve fiercely funny, mind-expanding chapters, Dawkins explains how the natural world arose without a designer—the improbability and beauty of the “bottom-up programming” that engineers an embryo or a flock of starlings—and challenges head-on some of the most basic assumptions made by the world’s religions: Do you believe in God? Which one? Is the Bible a “Good Book”? Is adhering to a religion necessary, or even likely, to make people good to one another? Dissecting everything from Abraham’s abuse of Isaac to the construction of a snowflake, Outgrowing God is a concise, provocative guide to thinking for yourself. Praise for Outgrowing God “My son came home from his first day in the sixth grade with arms outstretched plaintively demanding to know: ‘Have you ever heard of Jesus?’ We burst out laughing. Maybe not our finest parenting moment, given that he was genuinely distraught. He felt that he had woken up one day to a world in which his peers were expressing beliefs he found frighteningly unreasonable. He began devouring books like The God Delusion, books that helped him formulate his own arguments and helped him stand his ground. Dawkins’s new book is special in the terrain of atheists’ pleas for humanism and rationalism precisely since it speaks to those most vulnerable to the coercive tactics of religion. As Dawkins himself says in the dedication, this book is for ‘all young people when they’re old enough to decide for themselves.’ It is also, I must add, for their parents.”—Janna Levin, author of Black Hole Blues “When someone is considering atheism I tell them to read the Bible first and then Dawkins. Outgrowing God—second only to the Bible!”—Penn Jillette, author of God, No!
