A unique, wide-ranging examination of asteroid exploration and our future in space Human travel into space is an enormously expensive and unforgiving endeavor. So why go? In this accessible and authoritative book, astrophysicist Martin Elvis argues that the answer is asteroid exploration, for the strong motives of love, fear, and greed. Elvis's personal motivation is one of scientific love-asteroid investigations may teach us about the composition of the solar system and the origins of life. A more compelling reason may be fear-of a dinosaur killer-sized asteroid hitting our planet. Finally, Elvis maintains, we should consider greed: asteroids likely hold vast riches, such as large platinum deposits, and mining them could provide both a new industry and a funding source for bolder space exploration. Elvis explains how each motive can be satisfied, and how they help one another. From the origins of life to "space billiards" and space sports, Elvis looks at how asteroids may be used in the not-so-distant future.

The two most fascinating questions about extraterrestrial life are where it is found and what it is like. In particular, from our Earth-based vantage point, we are keen to know where the closest life to us is, and how similar it might be to life on our home planet. This book deals with both of these key issues. It considers possible homes for life, with a focus on Earth-like exoplanets. And it examines the possibility that life elsewhere might be similar to life here, due to the existence of parallel environments, which may result in Darwinian selection producing parallel trees of life between one planet and another. Understanding Life in the Universe provides an engaging and myth-busting overview for any reader interested in the existence and nature of extraterrestrial life, and the realistic possibility of discovering credible evidence for it in the near future.

An all-encompassing look at the history and enduring impact of the Apollo space program In Apollo's Legacy, space historian Roger D. Launius explores the many-faceted stories told about the meaning of the Apollo program and how it forever altered American society. The Apollo missions marked the first time human beings left Earth's orbit and visited another world, and thus they loom large in our collective memory. Many have detailed the exciting events of the Apollo program, but Launius offers unique insight into its legacy as seen through multiple perspectives. He surveys a wide range of viewpoints and narratives, both positive and negative, surrounding the program. These include the argument that Apollo epitomizes American technological--and political--progress; technological and scientific advances garnered from the program; critiques from both sides of the political spectrum about the program's expenses; and even conspiracy theories and denials of the program's very existence. Throughout the book, Launius weaves in stories from important moments in Apollo's history to draw readers into his analysis. Apollo's Legacy is a must-read for space buffs interested in new angles on a beloved cultural moment and those seeking a historic perspective on the Apollo program.

Scientists classify comets and asteroids that pass within 28 million miles of Earth's orbit as near-Earth objects (NEOs). Asteroids that collide and break into smaller fragments are the source of most NEOs, and the resulting fragments bombard the Earth at the rate of over 100 tons a day. Although the vast majority of NEOs that enter Earth's atmosphere disintegrate before reaching the surface, those larger than 100 meters (328 feet) may survive the descent and cause destruction in and around their impact sites. Furthermore, even smaller objects that disintegrate before reaching Earth's surface can cause significant damage. This book examines NASA's NEO Program and assesses the Agency's progress toward meeting statutory and other Program goals. Specifically, it reviews NASA's allocation and use of resources and plans for the future of the Program.

This book examines the recent shift in US space policy and the forces that continually draw the US back into a space-technology security dilemma. The dual-use nature of the vast majority of space technology, meaning of value to both civilian and military communities and being unable to differentiate offensive from defensive intent of military hardware, makes space an area particularly ripe for a security dilemma. In contrast to previous administrations, the Obama Administration has pursued a less militaristic space policy, instead employing a strategic restraint approach that stressed multilateral diplomacy to space challenges. The latter required international solutions and the United States, subsequently, even voiced support for an International Code of Conduct for Space. That policy held until the Chinese anti-satellite (ASAT) test in 2013, which demonstrated expanded Chinese capabilities. This volume explores the issues arising from evolving space capabilities across the world and the security challenges this poses. It subsequently discusses the complexity of the space environment and argues that all tools of national power must be used, with some degree of balance, toward addressing space challenges and achieving space goals. This book will be of much interest to students of space policy, defence studies, foreign policy, security studies and IR.

NASA is undertaking a trio of closely-related programs to continue human space exploration beyond low-Earth orbit: the SLS vehicle; the Orion capsule, which will launch atop the SLS and carry astronauts; and the supporting ground systems. As a whole, the efforts represent NASA's largest exploration investment over the next decade, potentially as much as $22 billion, to demonstrate initial capabilities. Beyond 2021, NASA plans to incrementally develop progressively more-capable SLS launch vehicles complemented by Orion capsules and ground systems. This book examines the scope of NASA's preliminary cost estimates for the three programs. It examines the SLS program's progress toward and risks for its first test flight in 2017; and the extent to which the SLS program has plans in place to achieve its long-term goals and promote affordability.

From Galileo's telescope to the International Space Station - a photo-filled tour through the milestones of space exploration This eclectic pop history of space exploration, by scientist-educator Sten Odenwald at NASA, examines 100 objects - all stunningly photographed - and their effect on what we know and how we think about space. Whimsical and uniquely clarifying, Space Exploration - A History in 100 Objects covers the iconic, from Sputnik to Skylab, as well as the lesser-known but utterly important: The ancient Greek Antikythera mechanism, the first known analog computer, which predicted astronomical movement. Luna 3, the first satellite to glimpse the far side of the moon. The O-ring; the humble, rubber part that doomed the Space Shuttle Challenger. Syncom 2, the first geosynchronous satellite, which made international TV possible. The V-2 rocket, the first artificial object to cross the threshold of space - and many more!

As featured in THE EDGE OF ALL WE KNOW - the new Netflix documentary about Black Holes For readers of Stephen Hawking, a fascinating account of the universe from the perspective of world-leading astrophysicist Heino Falcke, who took the first ever picture of a black hole. 10th April 2019: a global sensation. Heino Falcke, a man "working at the boundaries of his discipline and therefore at the limits of the universe" had used a network of telescopes spanning the entire planet to take the first picture of a black hole. Light in the Darkness examines how mankind has always looked to the skies, mapping the journey from millennia ago when we turned our gaze to the heavens, to modern astrophysics. Heino Falcke and Jorg Romer entertainingly and compellingly chart the breakthrough research of Falcke's team, an unprecedented global community of international colleagues developing a telescope complex enough to look directly into a black hole - a hole where light vanishes, and time stops. What does this development mean? Is this the beginning of a new physics? What can we learn from this about God, the world, and ourselves? For Falcke, astrophysics and metaphysics, science and faith, do not exclude one another. Black Hole is both a plea for curiosity and humility; it's interested in both what we know, and the mysteries that remain unsolved.

The goal of sending humans to Mars is becoming increasingly technologically feasible, but the prospect of space colonization raises important questions about civilizational ethics and collective morality. History shows how destructive colonialism has been, resulting in centuries-long struggles to achieve liberation from the violent competition for land and resources by colonial powers. Space settlement poses the same temptation on a cosmic scale, with commercial actors and government space agencies doing the work previously carried out by European empires. The question is whether humans will take a different approach in this new frontier.In Sovereign Mars, astrobiologist Jacob Haqq-Misra argues that settling Mars offers humankind a transformative opportunity to avoid the mistakes of the past by "liberating Mars" as a sovereign planet from the start. Rather than see space as a way to escape human problems on Earth, Mars presents humanity with a challenge to address these problems by thinking carefully about the theory and practice of civilization. Drawing on past examples of cooperative sovereignty, such as the Outer Space Treaty of 1967, the United Nations Law of the Sea Conventions, and the Antarctic Treaty System, Haqq-Misra begins a conversation about governance in space well in advance of the first arrival of humans on Mars and makes the case for an analogous approach to space that will preserve the space environment and benefit future generations. Haqq-Misra examines the emergence of sovereignty in space through the lens of historical precedent on Earth and develops models of shared governance that could maximize the transformative potential of Mars settlement. Sovereign Mars proposes the planet would serve humankind best as an independent planetary state, a juridical peer to Earth, to enable new experiments in human civilization and develop a pragmatic model for shared governance on Mars.

Are we alone in the universe? If not, where is everybody? An engaging exploration of one of the most important unsolved problems in science. Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity-but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: is there life, intelligent or otherwise, on other planets? This paradox (they're bound to be out there; but where are they?), first formulated by the famed physicist Enrico Fermi, has fueled decades of debate, speculation, and, lately, some actual science. Roush lays out the problem in its historical and modern-day context and summarizes the latest thinking among astronomers and astrobiologists. He describes the long history of speculation about aliens (we've been debating the idea for thousands of years); the emergence of SETI (the Search for Extraterrestrial Intelligence) as a scientific discipline in the 1960s, and scientists' use of radio and optical techniques to scan for signals; and developments in astrobiology (the study of how life might arise in non-Earth like environments) and exoplanet research (the discovery of planets outside our solar system). Finally, he discusses possible solutions to the Fermi Paradox and suggests way to refocus SETI work that might increase the chances of resolving the paradox-and finding extraterrestrials.

Spatial Cognitive Engine Technology discusses the increase in user demand for satellite wireless communication services that has led to the increasing development of spectrum resources and the fixed spectrum allocation mode which makes the utilization rate of spectrum resources lower. As an intelligent spectrum sharing technology, cognitive radio has innovated the traditional spectrum management system and is one of the effective ways to solve the above-mentioned problems. As the core of satellite cognitive radio, the spatial cognitive engine can use artificial intelligence to dynamically configure working parameters according to changes in the communication environment and user needs.

The story of the search for life on Mars-and the moral issues confronting us as we prepare to send humans there Does life exist on Mars? The question has captivated humans for centuries, but today it has taken on new urgency. NASA plans to send astronauts to Mars orbit by the 2030s. SpaceX wants to go by 2024, while Mars One wants to land a permanent settlement there in 2032. As we gear up for missions like these, we have a responsibility to think deeply about what kinds of life may already inhabit the planet--and whether we have the right to invite ourselves in. This book tells the complete story of the quest to answer one of the most tantalizing questions in astronomy. But it is more than a history. Life on Mars explains what we need to know before we go. David Weintraub tells why, of all the celestial bodies in our solar system, Mars has beckoned to us the most. He traces how our ideas about life on Mars have been refined by landers and rovers, terrestrial and Mars-orbiting telescopes, spectroscopy, and even a Martian meteorite. He explores how finding DNA-based life on the Red Planet could offer clues about our distant evolutionary past, and grapples with the profound moral and ethical questions confronting us as we prepare to introduce an unpredictable new life form-ourselves-into the Martian biosphere. Life on Mars is also a book about how science is done-and undone-in the age of mass media. It shows how Mars mania has obscured our vision since we first turned our sights on the planet and encourages a healthy skepticism toward the media hype surrounding Mars as humanity prepares to venture forth.

Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

This book is a comprehensive resource for understanding where the field stands, as well as providing a stepping stone for continued advancement of the field, from developing new techniques, to applying techniques on other planetary bodies.

Introduction by Professor Stephen Hawking. When Edwin Hubble looked into his telescope in the 1920s, he was shocked to find that nearly all of the galaxies he could see through it were flying away from one another. If these galaxies had always been travelling, he reasoned, then they must, at some point, have been on top of one another. This discovery transformed the debate about one of the most fundamental questions of human existence - how did the universe begin? Every society has stories about the origin of the cosmos and its inhabitants, but now, with the power to peer into the early universe and deploy the knowledge gleaned from archaeology, geology, evolutionary biology and cosmology, we are closer than ever to understanding where it all came from. In The Origin of (almost) Everything, New Scientist explores the modern origin stories of everything from the Big Bang, meteorites and dark energy, to dinosaurs, civilisation, timekeeping, belly-button fluff and beyond. From how complex life evolved on Earth, to the first written language, to how humans conquered space, The Origin of (almost) Everything offers a unique history of the past, present and future of our universe.
