If you have ever wondered about space travel, now you have the opportunity to understand it more fully than ever before. Traveling into space and even emigrating to nearby worlds may soon become part of the human experience. Scientists, engineers, and investors are working hard to make space tourism and colonization a reality. As astronauts can attest, extraterrestrial travel is incomparably thrilling. To make the most of the experience requires serious physical and mental adaptations in virtually every aspect of life, from eating to intimacy. Everyone who goes into space sees Earth and life on it from a profoundly different perspective than they had before liftoff. Astronomer and former NASA/ASEE scientist Neil F. Comins has written the go-to book for anyone interested in space exploration. He describes the wonders that travelers will encounter--weightlessness, unparalleled views of Earth and the cosmos, and the opportunity to walk on another world--as well as the dangers: radiation, projectiles, unbreathable atmospheres, and potential equipment failures. He also provides insights into specific trips to destinations including suborbital flights, space stations, the Moon, asteroids, comets, and Mars--the top candidate for colonization. Although many challenges are technical, Comins outlines them in clear language for all readers. He synthesizes key issues and cutting-edge research in astronomy, physics, biology, psychology, and sociology to create a complete manual for the ultimate voyage.

Earthrise tells the remarkable story of the first photographs of Earth from space and the totally unexpected impact of those images. The Apollo “Earthrise” and “Blue Marble” photographs were beamed across the world some forty years ago. They had an astounding effect, Robert Poole explains, and in fact transformed thinking about the Earth and its environment in a way that echoed throughout religion, culture, and science. Gazing upon our whole planet for the first time, we saw ourselves and our place in the universe with new clarity. Poole delves into new areas of research and looks at familiar history from fresh perspectives. With intriguing anecdotes and wonderful pictures, he examines afresh the politics of the Apollo missions, the challenges of whole Earth photography, and the story of the behind-the-scenes struggles to get photographs of the Earth put into mission plans. He traces the history of imagined visions of Earth from space and explores what happened when imagination met reality. The photographs of Earth represented a turning point, Poole contends. In their wake, Earth Day was inaugurated, the environmental movement took off, and the first space age ended. People turned their focus back toward Earth, toward the precious and fragile planet we call home.

Divided by continent, YOU ARE HERE represents one (idealized) orbit of the ISS. This planetary photo tour -- surprising, playful, thought-provoking, and visually delightful -- is also punctuated with fun, fascinating commentary on life in zero gravity. In the spirit of his bestselling An Astronaut's Guide to Life on Earth, YOU ARE HERE opens a singular window on our planet, using remarkable photographs to illuminate the history and consequences of human settlement, the magnificence (and wit) of never-before-noticed landscapes, and the power of the natural forces shaping our world and the future of our species.

Fluid distribution during spaceflight and impact on brain and vision health is an emerging field of high-priority research in the NASA human space program. International Space Station astronauts have developed ocular refraction changes during prolonged spaceflight. Within this book, experts review current data related to fluid shifts during microgravity exposure and the impact of fluid shifts on astronaut health. This work also compares current astronaut health problems with Earth-based health conditions such as elevated intracranial pressure and glaucoma. Chapters include discussion of altered fluid distribution, including intracellular and extracellular fluid shifts, eye morphology and vision disturbances, and intraocular pressure. In addition, chapters will include a discussion of advanced non-invasive technologies to investigate the abovementioned fluid volume and pressure variables. As such, the book aims to bridge health professionals, researchers, and science professionals by a presentation of ophthalmology topics critical to future human space exploration, thus providing new perspectives to solve emerging brain and eye disease on Earth and in Space.

Extending the spatial and temporal boundaries of human space flight is an important goal for the nation and for the National Aeronautics and Space Administration (NASA). However, human space flight remains an endeavor with substantial risks, and these risks must be identified, managed, and mitigated appropriately to achieve the nation's goals in space. The Bioastronautics Roadmap (BR) is the result of extensive, commendable efforts on the part of NASA to prioritize research efforts to meet these challenges. In 2003, NASA asked the Institute of Medicine (IOM), in collaboration with the Division on Engineering and Physical Sciences of the National Academies, to conduct a review of the BR. Specifically, NASA asked the committee to (1) conduct a comprehensive assessment and report of the strengths and weaknesses of the content and processes of the Bioastronautics Roadmap as applied to the missions described in the President's exploration initiative and (2) identify the unique challenges for accomplishing its goals and objectives. In September 2004, the committee released its preliminary report to NASA entitled Preliminary Considerations Regarding NASA's Bioastronautics Critical Path Roadmap. That document presented the committee's preliminary conclusions about the strengths and weaknesses of the April 2004 version of the BR. This report, A Risk Reductions Strategy for Human Exploration of Space, builds on those preliminary conclusions and provides recommendations to NASA about how to address the issues identified by the committee.

Since its inception, the U.S. human spaceflight program has grown from launching a single man into orbit to an ongoing space presence involving numerous crewmembers. As the U.S. space program evolves, propelled in part by increasing international and commercial collaborations, long duration or exploration spaceflights - such as extended stays on the International Space Station or missions to Mars - become more realistic. These types of missions will likely expose crews to levels of known risk that are beyond those allowed by current health standards, as well as to a range of risks that are poorly characterized, uncertain, and perhaps unforeseeable. As the National Aeronautics and Space Administration (NASA) and Congress discuss the next generation of NASA's missions and the U.S. role in international space efforts, it is important to understand the ethical factors that drive decision making about health standards and mission design for NASA activities. NASA asked the Institute of Medicine to outline the ethics principles and practices that should guide the agency's decision making for future long duration or exploration missions that fail to meet existing health standards. Health Standards for Long Duration and Exploration Spaceflight identifies an ethics framework, which builds on the work of NASA and others, and presents a set of recommendations for ethically assessing and responding to the challenges associated with health standards for long duration and exploration spaceflight.As technologies improve and longer and more distant spaceflight becomes feasible, NASA and its international and commercial partners will continue to face complex decisions about risk acceptability. This report provides a roadmap for ethically assessing and responding to the challenges associated with NASA's health standards for long duration and exploration missions. Establishing and maintaining a firmly grounded ethics framework for this inherently risky activity is essential to guide NASA's decisions today and to create a strong foundation for decisions about future challenges and opportunities.

Voyager 1 left the solar system in 2012; its sister craft, Voyager 2, will do so in 2015. The fantastic journey began in 1977, before the first episode of Cosmos aired. The mission was planned as a grand tour beyond the moon; beyond Mars, Jupiter, and Saturn; and maybe even into interstellar space. The fact that it actually happened makes this humanity's greatest space mission. In The Interstellar Age, award-winning planetary scientist Jim Bell reveals what drove and continues to drive the members of this extraordinary team.

Where would you look for alien life? An astronomer and science popularizer explains the basics of astrobiology to outline five plausible scenarios for finding extraterrestrials Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy.   Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks readers to imagine--and choose among--five scenarios for finding life. He encourages us to wonder whether life might exist within Mars's subsoil ice. He reveals the vital possibilities on the water-ice moons Europa and Enceladus. He views Saturn's moon Titan through the lens of our own planet's ancient past. And, he even looks beyond our solar system, investigating the top candidates for a "second Earth" in a myriad of exoplanets and imagining the case of a radio signal arriving from deep space. Covering the most up-to-date research, this accessibly written book provides readers with the basic knowledge necessary to decide where they would look for alien life.

Astronomers are on the verge of answering one of our most profound questions: are we alone in the universe? The ability to detect life in remote solar systems is at last within sight, and its discovery--even if only in microbial form--would revolutionize our self-image. Planet Hunters is the rollicking tale of the search for extraterrestrial life and the history of an academic discipline. Astronomer Lucas Ellerbroek takes readers on a fantastic voyage through space, time, history, and even to the future as he describes the field of exoplanet research, from the early ideas of sixteenth-century heretic Giordano Bruno to the discovery of the first exoplanet in 1995 to the invention of the Kepler Space Telescope. We join him on his travels as he meets with leading scientists in the field, including Michel Mayor, who discovered the first exoplanet, and Bill Borucki, principal investigator for NASA's Kepler mission. Taken together, the experiences, passion, and perseverance of the scientists featured here make the book an exciting and compelling read. Presenting cutting-edge research in a dynamic and accessible way, Planet Hunters is a refreshing look into a field where new discoveries come every week and paradigms shift every year.  

The universe is big. Really big. And it gets bigger every day. In Cosmological Enigmas, Mark Kidger weaves together history, science, and science fiction to consider questions about the bigness of space and the strange objects that lie trembling at the edge of infinity. What are quasars, blazars, and gamma-ray bursters? Could we ever travel to the stars? Can we really expect aliens to contact us? From the profound (what evidence do we have to support the big bang theory?) to the bizarre (can there be more than one universe and, if so, how many dimensions does it possess?) to the everyday-yet-profound (why is the sky dark at night?), Kidger explains not only what we know but how we came to know it. Reflecting on how stars shine and what may lie beyond the edge of the universe, Kidger takes us on the ultimate cosmic journey.

Safe Passage: Astronaut Care for Exploration Missions sets forth a vision for space medicine as it applies to deep space voyage. As space missions increase in duration from months to years and extend well beyond Earth (TM)s orbit, so will the attendant risks of working in these extreme and isolated environmental conditions. Hazards to astronaut health range from greater radiation exposure and loss of bone and muscle density to intensified psychological stress from living with others in a confined space. Going beyond the body of biomedical research, the report examines existing space medicine clinical and behavioral research and health care data and the policies attendant to them. It describes why not enough is known today about the dangers of prolonged travel to enable humans to venture into deep space in a safe and sane manner. The report makes a number of recommendations concerning NASA (TM)s structure for clinical and behavioral research, on the need for a comprehensive astronaut health care system and on an approach to communicating health and safety risks to astronauts, their families, and the public.

Topics cover the origin and evolution of life on Earth, the geological, physical and chemical conditions in which life might arise and the detection of extraterrestrial life on other planets and moons. The book also covers the history of our ideas on extraterrestrial life and the origin of life, as well as the ethical, philosophical and educational issues raised by astrobiology. Written to be accessible to students from diverse backgrounds, this text will be welcomed by advanced undergraduates and graduates who are taking astrobiology courses.

During the Gemini, Apollo, and Skylab flights, orbiting astronauts collected valuable information by means of observations and photography of Earth. Strengthened by the experience gained on these flights, the Earth Observations and Photography Experiment was carried out as on of the American objectives of the Apollo-Soyuz Test Project in July 1975. The main goal of the experiment was to utilize the special capabilities of trained observers (namely, the American astronauts of the joint mission) in visually studying and photographing specific Earth features and dynamic phenomena. These special capabilities include the sensitivity of the human eye to subtle color variations (e.g., to desert sands or sea water), and the speed with which the eye-brain interaction results in interpretation of the scene and recognition of important features. This latter capability allows instantaneous selection of important sites for photographic documentation at any moment, which in turn, enhances the quality of photographic data from space platforms. Another goal of the experiment was to establish the role of human observers in future space programs, particularly the Space Shuttle.This book contains a detailed account of the experiment objectives, training of astronauts, preparation of aids for their use, and the results of experiment performance. These details serve as a historical-archival record and as a guide for conducting similar projects in the future.The scientific objectives of the experiment included the collection of data in support of ongoing research in the fields of geology (particularly desert studies), oceanography, hydrology, meteorology, and environmental science. A summary of significant results in given; however, detailed scientific analyses are currently being performed by a number of investigators in various fields in the United States and abroad and their results will be published later, as a special publication of the National Aeronautics and Space Administration.

The first book to provide a serious and successful attempt at bringing the technical medical problems of space travel to a general audience.

Published to glowing praise in 1990, Science for All Americans defined the science-literate American--describing the knowledge, skills, and attitudes all students should retain from their learning experience--and offered a series of recommendations for reforming our system of education inscience, mathematics, and technology. Benchmarks for Science Literacy takes this one step further. Created in close consultation with a cross-section of American teachers, administrators, and scientists, Benchmarks elaborates on the recommendations to provide guidelines for what all students shouldknow and be able to do in science, mathematics, and technology by the end of grades 2, 5, 8, and 12. These grade levels offer reasonable checkpoints for student progress toward science literacy, but do not suggest a rigid formula for teaching. Benchmarks is not a proposed curriculum, nor is it aplan for one: it is a tool educators can use as they design curricula that fit their student's needs and meet the goals first outlined in Science for All Americans. Far from pressing for a single educational program, Project 2061 advocates a reform strategy that will lead to more curriculumdiversity than is common today.IBenchmarks emerged from the work of six diverse school-district teams who were asked to rethink the K-12 curriculum and outline alternative ways of achieving science literacy for all students. These teams based their work on published research and the continuing advice of prominent educators, aswell as their own teaching experience. Focusing on the understanding and interconnection of key concepts rather than rote memorization of terms and isolated facts, Benchmarks advocates building a lasting understanding of science and related fields. In a culture increasingly pervaded by science,mathematics, and technology, science literacy require habits of mind that will enable citizens to understand the world around them, make some sense of new technologies as they emerge and grow, and deal sensibly with problems that involve evidence, numbers, patterns, logical arguments, andtechnology--as well as the relationship of these disciplines to the arts, humanities, and vocational sciences--making science literacy relevant to all students, regardless of their career paths.If Americans are to participate in a world shaped by modern science and mathematics, a world where technological know-how will offer the keys to economic and political stability in the twenty-first century, education in these areas must become one of the nation's highest priorities. Together withScience for All Americans, Benchmarks for Science Literacy offers a bold new agenda for the future of science education in this country, one that is certain to prepare our children for life in the twenty-first century.
