Winner of the John W. Campbell Memorial Award for Best Science Fiction Novel When a giant meteor crashes into the earth and destroys all life, the small group of human survivors manage to leave the barren planet and establish a new home on the moon. From Tycho Base, men and woman are able to observe the devastated planet and wait for a time when return will become possible. Generations pass. Cloned children have had children of their own, and their eyes are raised toward the giant planet in the sky which long ago was the cradle of humanity. Finally, after millennia of waiting, the descendants of the original refugees travel back to a planet they've never known, to try and rebuild a civilization of which they've never been a part. The fate of the earth lies in the success of their return, but after so much time, the question is not whether they can rebuild an old destroyed home, but whether they can learn to inhabit an alien new world--Earth.

Humankind's first contact with an intelligent extraterrestrial species was not friendly. Because their star, a dying red dwarf, would soon fail to provide life-supporting warmth, a distant alien species recognized Earth, a planet similar to their world, perfect for their needs. In preparation for the move to Earth, the highly intelligent entities implemented a cleverly devised nanobot attack in an attempt to eradicate all life on Earth. They planned to follow the attack by sending a detachment to terraform the planet and assure all life on Earth was eliminated by the time they arrived. At least that was their plan. Fortunately, they didn't recognize the resolve of the human species to survive. While enlisting the extraordinary talents of a gifted physicist, the first attack was thwarted, but the aliens were not deterred. They had no choice. It was move or perish. With the immediate threat eliminated, Earth's scientist searched for the origin of the sinister nanobots and learned they came from a planet called Gliese 581-d that was more than twenty light-years away. They began to study the giant, water-covered planet and its weak, red dwarf star. A ten year study via the Hubble Space Telescope showed little change, and then one day, scientist were shocked to see a mammoth flotilla of alien spaceships assemble near the distant planet and set out on a course that would bring them to Earth. But, because Gliese 581-d was so far away, the scientist weren't too concerned. Even if the alien ships could travel at light-speed, it was decided it would be over two decades before they arrived. Because Einstein predicted nothing other than a photon can travel at light-speed, a theory later proven with the discovery of the Higgs Field, the flotilla wasn't expected to arrive in this century unless they could construct a stable wormhole, something no one believed they could. However, as a precaution, the world leaders decided to keep a close eye on the mammoth flotilla, code named Target One, and begin working on countermeasures should Target One arrive. They assumed they will have developed more advanced technology, and would be able to repel any future attacks. Should Target One show up in Earth's space earlier than expected, it would be a battle between the might of the greater numbered humans and their determination, against the superior technology of the lesser numbered aliens, and the outcome could not be determined. That was ten years ago, and in episode two, the surveillance continues . . .

Over 7 billion people depend on plants for healthy, productive, secure lives, but few of us stop to consider the origin of the plant kingdom that turned the world green and made our lives possible. And as the human population continues to escalate, our survival depends on how we treat the plant kingdom and the soils that sustain it. Understanding the evolutionary history of our land floras, the story of how plant life emerged from water and conquered the continents to dominate the planet, is fundamental to our own existence. In Making Eden David Beerling reveals the hidden history of Earth's sun-shot greenery, and considers its future prospects as we farm the planet to feed the world. Describing the early plant pioneers and their close, symbiotic relationship with fungi, he examines the central role plants play in both ecosystems and the regulation of climate. As threats to plant biodiversity mount today, Beerling discusses the resultant implications for food security and climate change, and how these can be avoided. Drawing on the latest exciting scientific findings, including Beerling's own field work in the UK, North America, and New Zealand, and his experimental research programmes over the past decade, this is an exciting new take on how plants greened the continents.

NEW YORK TIMES BESTSELLER • The national bestselling author of The God Equation 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. “Amazing … Kaku is in smooth perfect control of it the entire time.” —The Christian Science Monitor We are entering a new Golden Age of space exploration. With irrepressible enthusiasm and a deep understanding of the cutting-edge research in space travel, world-renowned physicist and futurist Dr. Michio Kaku presents a compelling vision of how humanity may develop a sustainable civilization in outer space. He reveals the developments in robotics, nanotechnology, and biotechnology that may allow us to terraform and build habitable cities on Mars and beyond. He then journeys out of our solar system and discusses how new technologies such as nanoships, laser sails, and fusion rockets may actually make interstellar travel a possibility. We travel beyond our galaxy, and even beyond our universe, as Kaku investigates some of the hottest topics in science today, including warp drive, wormholes, hyperspace, parallel universes, and the multiverse. Ultimately, he shows us how humans may someday achieve a form of immortality and be able to leave our bodies entirely, laser porting to new havens in space.

Terraforming is the process of making other worlds habitable for human life. This book asks how science fiction has imagined how we shape both our world and other planets and how stories of terraforming reflect on science, society and environmentalism. This title was made Open Access by libraries from around the world through Knowledge Unlatched.

Earth population: 1.8 billion. In a world already ravaged by climate change, society has become a dystopia of deep fake algorithms, vertical farms and digital totalitarianism. Among the very few remaining free thinkers, a retired extinction ecologist, a marine molecular biologist and a transgender woman accidentally discover a genetic locus that goes back to the origin of life on the planet. Will their discovery help them understand the biggest extinction event that Earth has ever faced? "This is impressing me like no author I've read since Kim Stanley Robinson. Bravo"

This book offers an exercise in theoretical planetology, presenting five different scenarios to assess the evolution of habitable conditions on Mars to assess planetary terraforming potential and to give insight into the ongoing search for habitable exoplanets. Four of the scenarios involve Martian satellite capture models, in which gravitational capture via tidal deformation and energy dissipation processes are measured to predict a pathway of biological evolution, while the fifth scenario analyzes the possible model that led to the Mars that we have today (i.e. with no life forms). In ten chapters, readers will learn how a Mars-like terrestrial planet can be transformed into a habitable planet, and what conditions must be assessed when searching for exoplanets in a star-centered orbit to support life. The book is intended for planetologists, and general enthusiasts of planetary evolution and our solar system.

TERRAFORMING MARS This book provides a thorough scientific review of how Mars might eventually be colonized, industrialized, and transformed into a world better suited to human habitation. The idea of terraforming Mars has, in recent times, become a topic of intense scientific interest and great public debate. Stimulated in part by the contemporary imperative to begin geoengineering Earth, as a means to combat global climate change, the terraforming of Mars will work to make its presently hostile environment more suitable to life—especially human life. Geoengineering and terraforming, at their core, have the same goal—that is to enhance (or revive) the ability of a specific environment to support human life, society, and industry. The chapters in this text, written by experts in their respective fields, are accordingly in resonance with the important, and ongoing discussions concerning the human stewardship of global climate systems. In this sense, the text is both timely and relevant and will cover issues relating to topics that will only grow in their relevance in future decades. The notion of terraforming Mars is not a new one, as such, and it has long played as the background narrative in many science fiction novels. This book, however, deals exclusively with what is physically possible, and what might conceivably be put into actual practice within the next several human generations. Audience Researchers in planetary science, astronomy, astrobiology, space engineering, architecture, ethics, as well as members of the space industry.

Climate engineering is a dystopian project. But as the human species hurtles ever faster towards its own extinction, geoengineering as a temporary fix, to buy time for carbon removal, is a seductive idea. We are right to fear that geoengineering will be used to maintain the status quo, but is there another possible future after geoengineering? Can these technologies and practices be used to bring carbon levels back down to pre-industrial levels? Are there possibilities for massive intentional intervention in the climate that are democratic, decentralised, or participatory? These questions are provocative, because they go against a binary that has become common sense: geoengineering is assumed to be on the side of industrial agriculture, inequality and ecomodernism, in opposition to degrowth, renewable energy, sustainable agriculture and climate justice. After Geoengineering rejects this binary, to ask: what if the people seized the means of climate production? Both critical and utopian, the book examines the possible futures after geoengineering. Rejecting the idea that geoengineering is some kind of easy work-around, Holly Buck outlines the kind of social transformation that would be necessary to enact a programme of geoengineering in the first place.
