Mathematician Lakshmi Nayak receives a letter from her future self about faster-than-light travel. The equations work, and the letter itself seems to prove the possibility will someday be realized. But her paper on the topic is fiercely criticized, and she’s warned away by a sinister Alliance agent. After defecting to the Union, she gets an unexpected offer: “I can build your ship.” Shipbuilder John Grant learns of a secret project, which unknown to the world has been traveling to the stars for decades: Black Horizon. Biologist Emma Hazeldene works for Black Horizon on an alien world, Apis, whose life has clearly come from Earth, investigating rock formations that are thought to be an alien, crystal-like intelligence. But refugees exiled to a hard life in the wilds of Apis already know more than the scientists have ever suspected. Everything changes when the rocks wake up, with dire results. As secrets emerge and rival powers seize advantage, three worlds are shaken to their foundations—and all involved have to fight for their lives, and their futures. Science fiction legend Ken MacLeod begins a new space opera trilogy by imagining humankind on the precipice of discovery—the invention of faster-than-light travel unlocks a universe of new possibilities, and new dangers.

With the invention of faster-than-light travel there is nowhere that humanity cannot go. New worlds are discovered, but with them come new dangers. At the heart of the discovery is the Fermi, mysterious beings that have survived on alien worlds for longer than humanity has existed. But now the Fermi are awakening, and they do not seem pleased to find humans in their midst. But for Lakshmi Nayak and the crew of the Fighting Chance, danger is a lot closer to home. Their search for answers will take them to places, and worlds, they never expected.

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.

Kaufman details the incredible true story of science's search for the beginnings of life on Earth and the probability that it exists elsewhere in the universe.

In 1988 Todd discovered the secret of time travel from his step brother Jeff. Together they traveled to the Fourth Dimension where they met a species made of energy. The encounter quickly led to war as Todd assembled a team to explore and fight with him and Jeff. After a three year period the journeys into the Fourth Dimension along with war against the energy beings suddenly stopped. Twenty years later Todd becomes obsessed with time travel once again and wants to return to the Fourth Dimension. He assembles a new team after creating a new device to get him there as he begins a new series of explorations, along with his kids.

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.

“Expansive and enlightening. . . . Impey packs his prose with wonderful anecdotes and weird factoids.”—New York Times Book Review 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. A dazzling and propulsive voyage through space and time, Beyond reveals how centuries of space explorers—from the earliest stargazers to today’s cutting-edge researchers—all draw inspiration from an innate human emotion: wanderlust. This urge to explore led us to multiply around the globe, and it can be traced in our DNA. Today, the urge to discover manifests itself in jaw-dropping ways: plans for space elevators poised to replace rockets at a fraction of the cost; experiments in suspending and reanimating life for ultra-long-distance travel; prototypes for solar sails that coast through space on the momentum of microwaves released from the Earth. With these ventures, private companies and entrepreneurs have the potential to outpace NASA as the leaders in a new space race. Combining expert knowledge of astronomy and avant-garde technology, Chris Impey guides us through the heady possibilities for the next century of exploration. In twenty years, a vibrant commercial space industry will be operating. In thirty years, there will be small but viable colonies on the Moon and Mars. In fifty years, mining technology will have advanced enough to harvest resources from asteroids. In a hundred years, a cohort of humans born off-Earth will come of age without ever visiting humanity’s home planet. This is not the stuff of science fiction but rather the logical extension of already available technologies. Beyond shows that space exploration is not just the domain of technocrats, but the birthright of everyone and the destiny of generations to come. To continue exploration is to ensure our survival. Outer space, a limitless unknown, awaits us.
