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.

Choice Highly Recommended Title, January 2020 This special edition of Apollo in Perspective marks the 50th anniversary of the Apollo 11 Moon landing in 1969. Updated and revised throughout, it takes a retrospective look at the Apollo space program and the technology that was used to land a man on the Moon. In addition, there is a new chapter looking forward to the future of contemporary spaceflight in returning to the Moon (project Artemis) and going on to Mars. Using simple illustrations and school-level mathematics, it explains the basic physics and technology of spaceflight, from how rockets work to the dynamics of orbits and how to simulate gravity in a rotating spacecraft. A mathematical appendix shows how some of the formulas can be derived. This is an excellent introduction to astronautics for anyone interested in space and spaceflight. Features: Accessible, written in a friendly and informal style Contains real-world examples Updated throughout, with new chapters on the Apollo missions and the immediate future of human spaceflight From the Foreword "I am sure there is a woman or a man alive today who will land on the Moon and on Mars. This book will certainly help them be ready for such a journey. Most importantly, it explains not only what happened 50 years ago, but how the Apollo missions happened, and the science that is required to do it again, or to go further, to Mars. If the reader is younger, still in school and perhaps considering the sciences, this book will introduce ideas that will help you choose the subjects to study which can help you to make your space travel a reality. For others, the book will be an exciting and thought provoking read that gives a vision of the near future in space, which all of us on planet Earth will be able to enjoy as the adventure unfolds."- Michael Foale, CBE, former-NASA astronaut

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.

Electrostatic Dust Mitigation and Manipulation Techniques for Planetary Dust explains how to control and remove dust in space due to the presence of a vacuum, abrasiveness of dust particles and electrostatic charge on particles. The book introduces innovative technologies that use electrostatic and di-electrophoretic forces to remove and transport small particles away from surfaces. In addition, it discusses how to resolve thermal control problems and reduce lung inhalation and eye irritation problems. The book includes two abrasive wear test devices that were designed to study the rate of volume wear for di?erent materials when subjected to lunar dust simulant of di?erent size ranges. This will be an ideal resource for space system engineers, space exploration researchers, and advanced students and professionals in space engineering.

Book & CD-ROM. pace weather refers to variations in the space environment between the sun and Earth (and throughout the solar system) that can affect technologies in space and on Earth. Space weather can disrupt the technology that forms the backbone of this country's economic vitality and national security, including satellite and airline operations, communications networks, navigation systems, and the electric power grid. As the Nation becomes ever more dependent on these technologies, space weather poses an increasing risk to infrastructure and the economy. Further, the Strategic National Risk Assessment has identified space weather as a hazard that poses significant risk to the security of the Nation. Clearly, reducing vulnerability to space weather needs to be a national priority. The National Space Weather Strategy (Strategy) and the accompanying National Space Weather Action Plan (Action Plan) together seek to enhance the integration of existing national efforts and to add important capabilities to help meet growing demands for space-weather information. The Strategy and Action Plan build on recent efforts to reduce risks associated with natural hazards and improve resilience of essential facilities and systems, aiming to foster a collaborative environment in which government, industry, and the American people can better understand and prepare for the effects of space weather. The Nation must continue to leverage existing public and private networks of expertise and capabilities and pursue targeted enhancements to improve the ability to manage risks associated with space weather. This book outlines objectives for enhancing the Nation's space-weather readiness in three key areas: national preparedness, forecasting, and understanding. It also describes the study process, the study requirements and their relevance and importance, an assessment and accounting of current and planned space weather observing systems used or to be used for operations, an analysis of gaps between the observing systems' capabilities and their ability to meet documented requirements, and a summary of key findings.

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.

Featuring over seventy images from the heroic age of space exploration, Through Astronaut Eyes presents the story of how human daring along with technological ingenuity allowed people to see the Earth and stars as they never had before. Photographs from the Mercury, Gemini, and Apollo programs tell powerful and compelling stories that continue to have cultural resonance to this day, not just for what they revealed about the spaceflight experience, but also as products of a larger visual rhetoric of exploration. The photographs tell us as much about space and the astronauts who took them as their reception within an American culture undergoing radical change throughout the turbulent 1960s. This book explores the origins and impact of astronaut still photography from 1962 to 1972, the period when human spaceflight first captured the imagination of people around the world. Photographs taken during those three historic programs are much admired and reprinted, but rarely seriously studied. This book suggests astronaut photography is particularly relevant to American culture based on how easily the images were shared through reproduction and circulation in a very visually oriented society. Space photography's impact at the crossroads of cultural studies, the history of exploration and technology, and public memory illuminates its continuing importance to American identity.

The mounting problem of space debris in low earth orbit and its threat to the operation of application satellites has been increasingly recognized as space activities increase. The efforts of the Inter Agency Space Debris Coordinating Committee (IADC) and UN COPUS have now led to international guidelines to mitigate the creation of new debris. This book discusses the technical studies being developed for active removal processes and otherwise mitigating problems of space debris, particularly in low earth orbit. This book also considers threats to space systems and the Earth that comes from natural causes such as asteroids, coronal mass ejections, and radiation. After more than half a century of space applications and explorations, the time has come to consider ways to provide sustainability for long-term space activities.

The desire to travel into space is as old as mankind itself. But it was not until the beginning of the 20th century that the idea became anything more than fiction. Although hot air balloons large enough to carry a person lifted off the ground in the late 1700s, it was the invention of powered flight-the airplane-that gave man hope of controlling his ascent into the skies and beyond. Once man was headed up, he could never again be satisfied being tied down to the earth's surface. The space age gave man hopes and dreams of a future in the exploration of the universe. These dreams were translated into souvenirs, toys, games, entertainment, and every-day items with the space theme. They are the artifacts of the space age. Collecting the Space Race explores these artifacts, beginning with the start of the 20th century. Included are first man on the moon items, the original Mercury astronaut items, Sputniks and satellites, fantasy items (Buck Rogers, Captain Video, Flash Gordon, Star Trek, etc.), UFOs, Ray Guns, space-theme postage stamps, mission patches, autographs, and space toys and robots. This book will inspire and answer some of the questions about the items that have been saved or collected as it exposes a broad field of things to collect.

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.

Progress in space safety lies in the acceptance of safety design and engineering as an integral part of the design and implementation process for new space systems. Safety must be seen as the principle design driver of utmost importance from the outset of the design process, which is only achieved through a culture change that moves all stakeholders toward front-end loaded safety concepts. This approach entails a common understanding and mastering of basic principles of safety design for space systems at all levels of the program organisation.

With the ongoing miniaturisation of components, the utility of smaller satellites is increasing. Many believe in the near future that small satellites will be able to perform all functions that larger satellites currently perform today. It has been suggested that these satellites will be less expensive, thus offer a lower risk to the consumer in case they fail before their mission design life. This book looks at the ability to build and operate smaller satellites with current technology to perform covert Space Control and Space Situational Awareness missions near geostationary orbit. The investigation determined if space qualified Commercial Off The Shelf (COTS) components and current technology could be used to build covert smaller satellites. The largest satellite was sized to be undetectable from earth based sensors. Subsequent CubeSat sizes were selected to determine how small a satellite could be built with COTS components and current technology to perform the assigned missions. A comparative analysis was then performed to determine how these satellites could be cost effectively launched to orbit. A cost estimate was performed to determine the entire life cycle cost for each satellite size excluding launch and integration segments. Using that information, the best satellite size was determined.
