"The world's leading alien hunter" -- New York Times Magazine From acclaimed Harvard astrophysicist and bestselling author of Extraterrestrial comes a mind-expanding new book explaining why becoming an interstellar species is imperative for humanity's survival and detailing a game plan for how we can settle among the stars. In the New York Times bestseller Extraterrestrial, Avi Loeb, the longest serving Chair of Harvard's Astronomy Department, presented a theory that shook the scientific community: our solar system, Loeb claimed, had likely been visited by a piece of advanced alien technology from a distant star. This provocative and persuasive argument opened millions of minds internationally to the vast possibilities of our universe and the existence of intelligent life beyond Earth. But a crucial question remained: now that we are aware of the existence of extraterrestrial life, what do we do next? How do we prepare ourselves for interaction with interstellar extraterrestrial civilization? How can our species become interstellar? Now Loeb tackles these questions in a revelatory, powerful call to arms that reimagines the idea of contact with extraterrestrial civilizations. Dismantling our science-fiction fueled visions of a human and alien life encounter, Interstellar provides a realistic and practical blueprint for how such an interaction might actually occur, resetting our cultural understanding and expectation of what it means to identify an extraterrestrial object. From awe-inspiring searches for extraterrestrial technology, to the heated debate of the existence of Unidentified Aerial Phenomena, Loeb provides a thrilling, front-row view of the monumental progress in science and technology currently preparing us for contact. He also lays out the profound implications of becoming--or not becoming--interstellar; in an urgent, eloquent appeal for more proactive engagement with the world beyond ours, he powerfully contends why we must seek out other life forms, and in the process, choose who and what we are within the universe. Combining cutting edge science, physics, and philosophy, Interstellar revolutionizes the approach to our search for extraterrestrial life and our preparation for its discovery. In this eye-opening, necessary look at our future, Avi Loeb artfully and expertly raises some of the most important questions facing us as humans, and proves, once again, that scientific curiosity is the key to our survival.

The untold story of the historic voyage to the moon that closed out one of our darkest years with a nearly unimaginable triumph In August 1968, NASA made a bold decision: in just sixteen weeks, the United States would launch humankind's first flight to the moon. Only the year before, three astronauts had burned to death in their spacecraft, and since then the Apollo program had suffered one setback after another. Meanwhile, the Russians were winning the space race, the Cold War was getting hotter by the month, and President Kennedy's promise to put a man on the moon by the end of the decade seemed sure to be broken. But when Frank Borman, Jim Lovell and Bill Anders were summoned to a secret meeting and told of the dangerous mission, they instantly signed on. Written with all the color and verve of the best narrative non-fiction, Apollo 8 takes us from Mission Control to the astronaut's homes, from the test labs to the launch pad. The race to prepare an untested rocket for an unprecedented journey paves the way for the hair-raising trip to the moon. Then, on Christmas Eve, a nation that has suffered a horrendous year of assassinations and war is heartened by an inspiring message from the trio of astronauts in lunar orbit. And when the mission is over--after the first view of the far side of the moon, the first earth-rise, and the first re-entry through the earth's atmosphere following a flight to deep space--the impossible dream of walking on the moon suddenly seems within reach. The full story of Apollo 8 has never been told, and only Jeffrey Kluger--Jim Lovell's co-author on their bestselling book about Apollo 13--can do it justice. Here is the tale of a mission that was both a calculated risk and a wild crapshoot, a stirring account of how three American heroes forever changed our view of the home planet.

The Case for Mars makes living in space seem more possible than ever in this updated 25th anniversary edition, featuring the latest information on the planet's exploration and the drive to send humans there. 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 had long been thought impossible to reach, let alone explore and inhabit. But that is changing fast. In February 2021, the American rover Perseverance will touch down on Mars. Equipped with a powerful suite of scientific instruments—including some that will attempt to make oxygen from the Martian atmosphere—the rover also carries a helicopter that will take spectacular panoramic movies from the air. Most exciting of all, a spectrometer onboard may find evidence of fossils left behind by microbes millions of years ago, when the planet was warm and wet, proving at last that life on Earth is not unique, but a general phenomenon in the universe. Meanwhile, in Boca Chica, Texas, Elon Musk’s SpaceX has created a shipyard that is building and testing the vessels that will take humans to Mars before this decade is out. Leading space exploration expert Robert Zubrin crafted the daring blueprint for humanity’s reach to the Red Planet twenty-five years ago, when he first published The Case for Mars . Now, in this updated edition, he looks to the future once more to describe how—in an era when the American space program and private companies like SpaceX are racing to send astronauts to Mars—our first colonies there are imminent. In the grand tradition of successful explorers, Zubrin calls for a travel-light and live-off-the-land approach to Martian settlement. He explains how scientists can use present-day technology to send humans to Mars, produce fuel and oxygen on the planet’s surface with its own natural resources, build bases and communities, and one day, terraform—or alter the atmosphere of the planet in order to pave the way for sustainable life. As a landmark new mission opens the decisive campaign to take humans to the Red Planet, Zubrin lays out a comprehensive plan to build life on a new world.
