Available in PDF, EPUB and Kindle. Book excerpt: This “smart analysis of the New Space sector” goes inside the rapid rise and dramatic rivalry of private space companies SpaceX and Blue Origin (The New York Times Book Review). For the outsize personalities staking their fortunes on spaceships, the new race to explore space could be a dead end, a lucrative opportunity—or the key to humanity’s survival. Rocket Billionaires shines a light on Elon Musk and Jeff Bezos as they attempt to make history, reinvent the space economy, and feed their own egos. Beyond these two towering figures, Tim Fernholz introduces a supporting cast of equally fascinating entrepreneurs, from the irrepressible British mogul Richard Branson to the satellite internet visionary Greg Wyler. Fernholz’s fly‑on‑the‑wall reporting captures an industry in the midst of disruption. While NASA seeks to preserve its ambitious space program, traditional aerospace firms like Boeing and Lockheed Martin scramble to adapt to new competitors, lobbyists tussle over public funds, and lawmakers try to prevent this new space race from sparking global conflict. It’s a high‑stakes marathon that Fernholz recounts with expert analysis and revealing detail. Featured on NPR and PBS’s SciTech Now, and in Fast Company, Forbes, and the Wall Street Journal

Available in PDF, EPUB and Kindle. Book excerpt: The historic quest to rekindle the human exploration and colonization of space led by two rivals and their vast fortunes, egos, and visions of space as the next entrepreneurial frontier The Space Barons is the story of a group of billionaire entrepreneurs who are pouring their fortunes into the epic resurrection of the American space program. Nearly a half-century after Neil Armstrong walked on the moon, these Space Barons-most notably Elon Musk and Jeff Bezos, along with Richard Branson and Paul Allen-are using Silicon Valley-style innovation to dramatically lower the cost of space travel, and send humans even further than NASA has gone. These entrepreneurs have founded some of the biggest brands in the world-Amazon, Microsoft, Virgin, Tesla, PayPal-and upended industry after industry. Now they are pursuing the biggest disruption of all: space. Based on years of reporting and exclusive interviews with all four billionaires, this authoritative account is a dramatic tale of risk and high adventure, the birth of a new Space Age, fueled by some of the world's richest men as they struggle to end governments' monopoly on the cosmos. The Space Barons is also a story of rivalry-hard-charging startups warring with established contractors, and the personal clashes of the leaders of this new space movement, particularly Musk and Bezos, as they aim for the moon and Mars and beyond.

Book excerpt: How do you get to the Red Planet? Not via a benighted government program trapped in red tape and bound by budget constrictions, thats for sure. No, what it will take is a helping of adventure, science, corporate powerplays, a generous dollop of seduction¾both in and out of the boardroom¾and money, money, money! Art Thrasher knows this. He is a man with a driving vision: send humans to Mars. The government has utterly failed, but Thrasher has got the plan to accomplish such a feat: form a _clubÓ or billionaires to chip in one billion a year until the dream is accomplished. But these are men and women who are tough cookies, addicted to a profitable bottom-line, and disdainful of pie-in-the-sky dreamers who want to use their cash to make somebody elses dreams come true. But Thrasher is different from the other dreamers in an important regarhes a billionaire himself, and the president of a successful company. But its going to take all his wiles as a captain of industry and master manipulator of business and capital to overcome setbacks and sabotage¾and get a rocket full of scientist, engineers, visionaries, and dreamers on their way to the Red Planet. The man for the job has arrived. Art Thrasher is prepared to do whatever it takes to humans on Mars¾or die trying!

Book excerpt: Thinking about climate change can create a paralysing sense of hopelessness. But what about the idea of a planetary exodus? Are high-tech solutions like colonizing other planets just another distraction from taking real action? This radical book unsettles how we think about taking responsibility for environmental catastrophe. Going beyond both hopelessness and false hope in his development of a ‘sociology of the very worst’, David W. Hill debunks the idea of a society that centres around human beings and calls for us to take responsibility for sustaining a coexistence of animals, plants and minerals bound by one planet. We would then find the centre of our moral gravity here together on earth.

Book excerpt: An optimistic--but realistic and feasible--action plan for fighting climate change while creating new jobs and a healthier environment: electrify everything. Climate change is a planetary emergency. We have to do something now—but what? Saul Griffith has a plan. In Electrify, Griffith lays out a detailed blueprint—optimistic but feasible—for fighting climate change while creating millions of new jobs and a healthier environment. Griffith’s plan can be summed up simply: electrify everything. He explains exactly what it would take to transform our infrastructure, update our grid, and adapt our households to make this possible. Billionaires may contemplate escaping our worn-out planet on a private rocket ship to Mars, but the rest of us, Griffith says, will stay and fight for the future. Griffith, an engineer and inventor, calls for grid neutrality, ensuring that households, businesses, and utilities operate as equals; we will have to rewrite regulations that were created for a fossil-fueled world, mobilize industry as we did in World War II, and offer low-interest “climate loans.” Griffith’s plan doesn’t rely on big, not-yet-invented innovations, but on thousands of little inventions and cost reductions. We can still have our cars and our houses—but the cars will be electric and solar panels will cover our roofs. For a world trying to bounce back from a pandemic and economic crisis, there is no other project that would create as many jobs—up to twenty-five million, according to one economic analysis. Is this politically possible? We can change politics along with everything else.

Book excerpt: Elon Musk, visionary behind SpaceX and CEO of both the electric car company Tesla and the social media platform Twitter, is constantly generating headlines. But how did he get there? This riveting and beautifully designed YA biography shows how a once-bullied school boy became a figure the New York Times described as "arguably the most important and successful entrepreneur in the world." Online banking, reusable rockets, electric sports cars, improved solar power, colonizing Mars—Elon Musk is full of unique, daring, and highly-publicized ideas that he believes will help save the world. But behind his legendary drive and the mind-blowing headlines seen on CNN, Forbes, or The Wall Street Journal is the story of a bullied and beaten school boy who, through creativity and determination, decided to rewrite his narrative and find groundbreaking ways to make the world a better place. With the sense of fun and style that he has become so well-known for, of course. From hosting raves to pay for college to rewriting the rules on space travel, Elon Musk has always gone his own way, to either the dismay or admiration of the general public. And now, award-winning investigative journalist Anna Crowley Redding takes readers on a well-researched trip through Elon's life and accomplishments.

Book excerpt: A San Francisco Chronicle Bestseller The New York Times’s Global Economics Correspondent masterfully reveals how billionaires’ systematic plunder of the world—brazenly accelerated during the pandemic—has transformed 21st-century life and dangerously destabilized democracy. “Davos Man will be read a hundred years from now as a warning.” —Evan Osnos “Excellent. A powerful, fiery book, and it could well be an essential one.” —NPR.org The history of the last half century in America, Europe, and other major economies is in large part the story of wealth flowing upward. The most affluent people emerged from capitalism’s triumph in the Cold War to loot the peace, depriving governments of the resources needed to serve their people, and leaving them tragically unprepared for the worst pandemic in a century. Drawing on decades of experience covering the global economy, award-winning journalist Peter S. Goodman profiles five representative “Davos Men”—members of the billionaire class—chronicling how their shocking exploitation of the global pandemic has hastened a fifty-year trend of wealth centralization. Alongside this reporting, Goodman delivers textured portraits of those caught in Davos Man’s wake, including a former steelworker in the American Midwest, a Bangladeshi migrant in Qatar, a Seattle doctor on the front lines of the fight against COVID, blue-collar workers in the tenements of Buenos Aires, an African immigrant in Sweden, a textile manufacturer in Italy, an Amazon warehouse employee in New York City, and more. Goodman’s revelatory exposé of the global billionaire class reveals their hidden impact on nearly every aspect of modern society: widening wealth inequality, the rise of anti-democratic nationalism, the shrinking opportunity to earn a livable wage, the vulnerabilities of our health-care systems, access to affordable housing, unequal taxation, and even the quality of the shirt on your back. Meticulously reported yet compulsively readable, Davos Man is an essential read for anyone concerned about economic justice, the capacity of societies to grapple with their greatest challenges, and the sanctity of representative government.

Book excerpt: The radical history of space exploration from the Russian Cosmists to Elon Musk Many societies have imagined going to live in space. What they want to do once they get up there - whether conquering the unknown, establishing space "colonies," privatising the moon's resources - reveals more than expected. In this fascinating radical history of space exploration, Fred Scharmen shows that often science and fiction have combined in the imagined dreams of life in outer space, but these visions have real implications for life back on earth. For the Russian Cosmists of the 1890s space was a place to pursue human perfection away from the Earth. For others, such as Wernher Von Braun, it was an engineering task that combined, in the Space Race, the Cold War, and during World War II, with destructive geopolitics. Arthur C. Clark in his speculative books offered an alternative vision of wonder that is indifferent to human interaction. Meanwhile NASA planned and managed the space station like an earthbound corporation. Today, the market has arrived into outer space and exploration is the plaything of superrich technology billionaires, who plan to privatise the mineral wealth for themselves. Are other worlds really possible? Bringing these figures and ideas together reveals a completely different story of our relationship with outer space, as well as the dangers of our current direction of extractive capitalism and colonisation.

Available in PDF, EPUB and Kindle. Book excerpt: "Space, to use a worn metaphor, is in the mind of the beholder. When we contemplate the seemingly limitless universe, we tend to project onto space our own hopes and dreams (as well as our fears and anxieties). But like responses to Rorschach inkblots, there are many different hopes, dreams, fears, and anxieties that one can project onto the night's sky. To those who approach it with a thirst for profits, space appears as a resource-rich goldmine, beckoning to anyone with enough wealth and privilege to take advantage of untapped markets. To those who approach it with a yearning for human expansion, space appears as a frontier that is humanity's birthright to conquer, its new manifest destiny. To those who approach it with a passion for knowledge and understanding, space appears as a tantalizing and pristine laboratory for scientific exploration. In these ways, our visions for humanity's future in space--what planets and moons we hope to visit, what we hope to accomplish when we get there--are more products of our perspectives about space (and our underlying worldviews and value systems) than anything else"--

Available in PDF, EPUB and Kindle. Book excerpt: This book explores the privatization of space and its global impact on the future of commerce, peace and conflict. As space becomes more congested, contested, and competitive in the government and the private arenas, the talk around space research moves past NASA’s monopoly on academic and cultural imaginations to discuss how Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin is making space "cool" again. This volume addresses the new rhetoric of space race and weaponization, with a focus on how the costs of potential conflict in space would discourage open conflict and enable global cooperation. It highlights the increasing dependence of the global economy on space research, its democratization, plunging costs of access, and growing economic potential of space-based assets. Thoughtful, nuanced, well-documented, this book is a must read for scholars and researchers of science and technology studies, space studies, political studies, sociology, environmental studies, and political economy. It will also be of much interest to policymakers, bureaucrats, think tanks, as well as the interested general reader looking for fresh perspectives on the future of space.

Available in PDF, EPUB and Kindle. Book excerpt: A navigational aid to the apocalypse. Steve Beard's Six Concepts for the End of the World mixes scientific research with experimental fiction to produce a manual for the apocalypse. The author examines six disciplines—technology, sociology, geography, psychology, theology and narratology—and for each one creates a fictional scenario that both reflects and energizes the research, all under the guiding light of the philosopher Paul Virilio's theories. This approach allows Beard to create one surprising idea after another: Hollywood viewed as a research and development lab for the end times, a first-person account of a UFO abduction, a blog on the disappearance of the Malaysian Airlines flight 370, a voice-over for an imaginary film by a doomsday cult member. Highly original in both form and content, the book surprises and delights in its scope. The approach is multidisciplinary and multidirectional, and Beard's exploration ranges over many areas and themes, always bringing distinctive insights to bear. Six Concepts for the End of the World is an expertly guided tour through the author's imagination, and toward the end of the world.
