The human race is at a crossroads. In the coming years, we will make decisions regarding our human spaceflight program that will lead to one of two familiar futures: the open universe of Star Trek, where we allow ourselves the opportunity to spread our wings and attempt to flourish as an interplanetary species - or the closed, dystopian, and ultimately self-destructive world of Soylent Green. If we ever hope to live in the future that is the former scenario, our first stepping stone must be a manned mission to Mars.

Since the beginning of human history Mars has been an alluring dream - the stuff of legends, gods, and mystery. The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit. Now with the advent of a revolutionary new plan, all this has changed. Leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with engaging anecdotes. The Case for Mars is not a vision for the far future or one that will cost us impossible billions.

In the gripping Never Panic Early, Fred Haise, Lunar Module Pilot for Apollo 13, offers a detailed firsthand account of when disaster struck three days into his mission to the moon. An oxygen tank exploded, a crewmate uttered the now iconic words, “Houston, we’ve had a problem here,” and the world anxiously watched as one of history’s most incredible rescue missions unfolded. Haise brings listeners into the heart of his experience on the challenging mission—considered NASA’s finest hour—and reflects on his life and career as an Apollo astronaut.

Based on remarkable new research, acclaimed historian Alexander Rose brings to life the true story of the spy ring that helped America win the Revolutionary War. For the first time, Rose takes us beyond the battlefront and deep into the shadowy underworld of double agents and triple crosses, covert operations and code breaking, and unmasks the courageous, flawed men who inhabited this wilderness of mirrors—including the spymaster at the heart of it all.

Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon.

Colonel Chris Hadfield has spent decades training as an astronaut and has logged nearly 4000 hours in space. During this time he has broken into a Space Station with a Swiss army knife, disposed of a live snake while piloting a plane, and been temporarily blinded while clinging to the exterior of an orbiting spacecraft. The secret to Col. Hadfield's success - and survival - is an unconventional philosophy he learned at NASA: prepare for the worst and enjoy every moment of it.

The number-one best-selling author of The Future of the Mind traverses the frontiers of astrophysics, artificial intelligence, and technology to offer a stunning vision of man's future in space, from settling Mars to traveling to distant galaxies. Formerly the domain of fiction, moving human civilization to the stars is increasingly becoming a scientific possibility - and a necessity. Whether in the near future due to climate change and the depletion of finite resources or in the distant future due to catastrophic cosmological events, humans will one day need to leave Earth.

In what is considered one of Heinlein's most hair-raising, thought-provoking, and outrageous adventures, the master of modern science fiction tells the strange story of an even stranger world. It is 21st-century Luna, a harsh penal colony where a revolt is plotted between a bashful computer and a ragtag collection of maverick humans, a revolt that goes beautifully until the inevitable happens. But that's the problem with the inevitable: it always happens.

That man should have dominion “over all the earth, and over every creeping thing that creepeth upon the earth” is a prophecy that has hardened into fact. So pervasive are human impacts on the planet that it’s said we live in a new geological epoch: the Anthropocene. The question we now face is: Can we change nature, this time in order to save it? Elizabeth Kolbert, the Pulitzer Prize-winning author of The Sixth Extinction, takes a hard look at the new world we are creating.

Imagine a young ER doctor confronting a patient in the Lonely Pines Hospital emergency room in 1981 Ohio, where both of their lives might be turned upside down and spun in a completely different direction. This riveting medical sci-fi story will have you wondering if you’ve ever experienced a similar bizarre incident, and how time, space, and historical events may be more fluid than we ever thought possible. Beware; a strange visitor may already have your number.

Bill Bryson has been an enormously popular author both for his travel books and for his books on the English language. Now, this beloved comic genius turns his attention to science. Although he doesn't know anything about the subject (at first), he is eager to learn, and takes information that he gets from the world's leading experts and explains it to us in a way that makes it exciting and relevant.

Trust was rare and precious in the wide-open towns that sprung up like weeds on America's frontier - with hustlers and hucksters arriving in droves by horse, coach, wagon, and rail, and gunmen working both sides of the law, all too eager to end a man's life with a well-placed bullet. The New York Times best-selling grand master of suspense deftly displays the other side of his genius, with seven classic Western tales of destiny and fatal decision...and trust as essential to survival as it is hard-earned.

You will learn how to develop your own communication system with spirits and Spirit Guides, as well as develop an understanding of what they are trying to communicate with you right now!

There are many forms of spirit communication and it is important for you to find out what particular system works best for you.

Nine brilliant scientists travel light-years on a one-way trip to an Earthlike planet. Their mission is to study from orbit the two species of intelligent lifeforms on the surface. The first: an isolated people embarking on civilization and building their world's first city. The second: a brutal race of massive predators, spread thick and still growing across the dominant landmass - destined to breed and eat their way to extinction within a few centuries.

In 1879, Steve Dancy sells his New York shop and ventures west to explore and write a journal about his adventures. Though he's not looking for trouble, Dancy's infatuation with another man's wife soon embroils him in a deadly feud with Sean Washburn, a Nevada silver baron. Infuriated by the outrages of two hired thugs, the shopkeeper kills both men in an impulsive street fight.

Beyond dares to imagine a fantastic future for humans in space - and then reminds us that we're already there. Human exploration has been an unceasing engine of technological progress, from the first homo sapiens to leave our African cradle to a future in which mankind promises to settle another world. Beyond tells the epic story of humanity leaving home - and how humans will soon thrive in the vast universe beyond the Earth.

With his signature wit and thought-provoking insights, Neil deGrasse Tyson - one of our foremost thinkers on all things space - illuminates the past, present, and future of space exploration and brilliantly reminds us why NASA matters now as much as ever. As Tyson reveals, exploring the space frontier can profoundly enrich many aspects of our daily lives, from education systems and the economy to national security and morale.

Since its formation nearly five billion years ago, our planet has been the sole living world in a vast and silent universe. Now, Earth's isolation is coming to an end. Over the past two decades, astronomers have discovered thousands of "exoplanets" orbiting other stars, including some that could be similar to our own world. Studying those distant planets for signs of life will be crucial to understanding life's intricate mysteries right here on Earth. In a firsthand account of this unfolding revolution, Lee Billings draws on interviews with top researchers.

Icy, rocky, sometimes dusty, always mysterious – comets and asteroids are among the Solar System's very oldest inhabitants, formed within a swirling cloud of gas and dust in the area of space that eventually hosted the Sun and its planets. Locked within each of these extra-terrestrial objects is the 4.6-billion-year wisdom of Solar System events, and by studying them at close quarters using spacecraft we can coerce them into revealing their closely-guarded secrets. This offers us the chance to answer some fundamental questions about our planet and its inhabitants.

In The Vanishing Face of Gaia, British scientist James Lovelock predicts global warming will lead to a Hot Epoch. Lovelock is best known for formulating the controversial Gaia theory in the 1970s, with Ruth Margulis of the University of Massachusetts, which states that organisms interact with and regulate Earth's surface and atmosphere. We ignore this interaction at our peril.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

End Times is a compelling work of skilled reportage that peels back the layers of complexity around the unthinkable - and inevitable - end of humankind. From asteroids and artificial intelligence to volcanic supereruption to nuclear war, veteran science reporter and TIME editor Bryan Walsh provides a stunning panoramic view of the most catastrophic threats to the human race.

This engaging memoir reveals the true story of the Search for ExtraterrestrialIntelligence (SETI), and discloses what we may very soon discover. Chronicling the program’s history with insight and humor, SETI senior astronomer Seth Shostak assures us that if there is sentient life in the universe, we are within decades of picking up its signal.

Since its 2009 launch, the Kepler satellite has discovered more than 2,000 exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, remarkable in their variety. Astronomer Michael Summers and physicist James Trefil explore these remarkable recent discoveries: planets revolving around pulsars, planets made of diamond, planets that are mostly water, and numerous rogue planets wandering through the emptiness of space.

While everything appears to be collapsing around us - ecodamage, genetic engineering, virulent diseases, water shortages, global famine, wars - we can still do something about it and create a world that will work for us and for our children's children. The inspiration for Leonardo DiCaprio's feature documentary movie The 11th Hour, The Last Hours of Ancient Sunlight details what is happening to our planet, the reasons for our culture's blind behavior, and how we can fix the problem.

In this provocative and optimistic rebuke to the catastrophists, Robert Bryce shows how innovation and the inexorable human desire to make things Smaller Faster Lighter Denser Cheaper is providing consumers with Cheaper and more abundant energy, Faster computing, Lighter vehicles, and myriad other goods. That same desire is fostering unprecedented prosperity, greater liberty, and yes, better environmental protection.

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

In 1959, the Soviet probe Luna 3 took the first photos of the far side of the Moon. Even in their poor resolution, the images stunned scientists: The far side is an enormous mountainous expanse, not the vast lava plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. When the Earth Had Two Moons is an astonishing exploration of planet formation and the origins of life by one of the world’s most innovative planetary geologists.
