Book Description
Ever since the completion of the Apollo program, there has been a lack of consensus about the future of human spaceflight. The Columbia tragedy in February 2003 rekindled public debate about this question. In November 2003, the Space Studies Board and the Aeronautics and Space Engineering Board organized a workshop to explore aspects of the question, what should be the principal purpose, goals, and priorities of the U.S. civil space program? This report presents a factual summary of that workshop, which identified past lessons learned and guiding principles for the future of the civil space program. Seven broad themes emerged from the workshop, and these themes are highlighted in the report. The report also presents discussions of strategies for the human spaceflight program and guiding principles of and boundary conditions for a 21st century space policy.

Rocket Dreams
Author: Marina Benjamin
Publisher: Simon and Schuster
ISBN: 0743254171
Category : Social Science
Languages : en
Pages : 257
Book Description
In 1958, mankind's centuries-long flirtation with space flight became a torrid love affair. For a decade, tens of millions of people were enraptured -- first, by the U.S.-Soviet race to the moon, and finally, as America outstripped its rival, by Project Apollo alone. It is now more than three decades since the last man walked on the moon...more time than between the first moonwalk and the beginning of World War II. Apollo did not, as had been promised by a generation of visionaries, herald the beginning of the Space Age, but its end. Or did it? Project Apollo, like a cannonball, reached its apogee and returned to earth, but the trajectory of that return was complex. America's atmosphere -- its economic, scientific, and cultural atmosphere -- made for a very complicated reentry that produced many solutions to the trajectory problem. Rocket Dreams is about those solutions...about the places where the space program landed. In Rocket Dreams, an extraordinarily talented young writer named Marina Benjamin will take you on a journey to those landing sites. A visit with retired astronauts at a celebrity autograph show is a starting point down the divergent paths taken by the pioneers, including Edgar Mitchell, founder of the "church" of Noëtic Sciences. Roswell, New Mexico is a landing site of a different order, the "magnetic north" of UFO belief in the United States -- a belief that began its most dramatic growth precisely at the time that the path of the space program began its descent. In the vernacular, the third law of motion states that what goes up, must come down. Thus the tremendous motive force that energized the space program didn't just vanish; it was conserved and transformed, making bestsellers out of fantasy literature, spawning Gaia, and giving symbolism to the environmental movement. Everything from the pop cultural boom in ufology to the worldwide Search for Extra-Terrestrial Intelligence (SETI) feeds on the energy given off by America's leap toward space. Rocket Dreams is an eloquent tour of this Apollo-scarred landscape. It is also an introduction to some of the most fascinating characters imaginable: Some long dead, like the crackpot visionary Alfred Lawson, who saw in space flight a new stage of human evolution ("Alti-Man"), or Robert Goddard, the father of rocketry, whose workshop in Roswell stands only half a mile from shops selling posters of alien visitors. Others are very much alive -- like Stewart Brand, creator of the Whole Earth Catalog and partner with Gerard O'Neill in the drive to build free-floating space colonies, and SETI astronomer Seth Shostak, who has spent decades listening to the skies, hoping for the first contact with another intelligent species. Perceptive, original, and wonderfully written, informed by history, science, and an acute knowledge of popular culture, Rocket Dreams is a brilliant book by a remarkable talent.

Recapturing a Future for Space Exploration

Languages : en
Pages : 464
Book Description
More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.

Dark Skies
Author: Daniel Deudney
Publisher: Oxford University Press
ISBN: 019090335X
Category : Political Science
Languages : en
Pages : 465
Book Description
Space is again in the headlines. E-billionaires Jeff Bezos and Elon Musk are planning to colonize Mars. President Trump wants a "Space Force" to achieve "space dominance" with expensive high-tech weapons. The space and nuclear arms control regimes are threadbare and disintegrating. Would-be asteroid collision diverters, space solar energy collectors, asteroid miners, and space geo-engineers insistently promote their Earth-changing mega-projects. Given our many looming planetary catastrophes (from extreme climate change to runaway artificial superintelligence), looking beyond the earth for solutions might seem like a sound strategy for humanity. And indeed, bolstered by a global network of fervent space advocates-and seemingly rendered plausible, even inevitable, by oceans of science fiction and the wizardly of modern cinema-space beckons as a fully hopeful path for human survival and flourishing, a positive future in increasingly dark times. But despite even basic questions of feasibility, will these many space ventures really have desirable effects, as their advocates insist? In the first book to critically assess the major consequences of space activities from their origins in the 1940s to the present and beyond, Daniel Deudney argues in Dark Skies that the major result of the "Space Age" has been to increase the likelihood of global nuclear war, a fact conveniently obscured by the failure of recognize that nuclear-armed ballistic missiles are inherently space weapons. The most important practical finding of Space Age science, also rarely emphasized, is the discovery that we live on Oasis Earth, tiny and fragile, and teeming with astounding life, but surrounded by an utterly desolate and inhospitable wilderness stretching at least many trillions of miles in all directions. As he stresses, our focus must be on Earth and nowhere else. Looking to the future, Deudney provides compelling reasons why space colonization will produce new threats to human survival and not alleviate the existing ones. That is why, he argues, we should fully relinquish the quest. Mind-bending and profound, Dark Skies challenges virtually all received wisdom about the final frontier.

Languages : en
Pages : 317
Book Description
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'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'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.

Issues Affecting the Future of the U.S. Space Science and Engineering Workforce
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309102170
Category : Science
Languages : en
Pages : 60
Book Description
In January 2006, the President announced a new civilian space policy focusing on exploration. As part of its preparations to implement that policy, NASA asked the NRC to explore long-range science and technology workforce needs to achieve the space exploration vision, identify obstacles to filling those needs, and put forward solutions to those obstacles. As part of the study, the NRC held a workshop to identify important factors affecting NASA's future workforce and its capacity to implement the exploration vision. This interim report presents a summary of the highlights of that workshop and an initial set of findings. The report provides a review of the workforce implications of NASA's plans, an assessment of science and technology workforce demographics, an analysis of factors affecting the aerospace workforce for both NASA and the relevant aerospace industry, and preliminary findings and recommendations. A final report is scheduled for completion in early 2007.

Ronald Reagan and the Space Frontier
Author: John M. Logsdon
Publisher: Springer
ISBN: 3319989626
Category : History
Languages : en
Pages : 419
Book Description
When Ronald Reagan was elected in 1980, limits on NASA funding and the lack of direction under the Nixon and Carter administrations had left the U.S. space program at a crossroads. In contrast to his predecessors, Reagan saw outer space as humanity’s final frontier and as an opportunity for global leadership. His optimism and belief in American exceptionalism guided a decade of U.S. activities in space, including bringing the space shuttle into operation, dealing with the 1986 Challenger accident and its aftermath, committing to a permanently crewed space station, encouraging private sector space efforts, and fostering international space partnerships with both U.S. allies and with the Soviet Union. Drawing from a trove of declassified primary source materials and oral history interviews, John M. Logsdon provides the first comprehensive account of Reagan’s civilian and commercial space policies during his eight years in the White House. Even as a fiscal conservative who was hesitant to increase NASA’s budget, Reagan’s enthusiasm for the space program made him perhaps the most pro-space president in American history.

Pathways to Exploration
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309305101
Category : Science
Languages : en
Pages : 405
Book Description
The United States has publicly funded its human spaceflight program on a continuous basis for more than a half-century, through three wars and a half-dozen recessions, from the early Mercury and Gemini suborbital and Earth orbital missions, to the lunar landings, and thence to the first reusable winged crewed spaceplane that the United States operated for three decades. Today the United States is the major partner in a massive orbital facility - the International Space Station - that is becoming the focal point for the first tentative steps in commercial cargo and crewed orbital space flights. And yet, the long-term future of human spaceflight beyond this project is unclear. Pronouncements by multiple presidents of bold new ventures by Americans to the Moon, to Mars, and to an asteroid in its native orbit, have not been matched by the same commitment that accompanied President Kennedy\'s now fabled 1961 speech-namely, the substantial increase in NASA funding needed to make it happen. Are we still committed to advancing human spaceflight? What should a long-term goal be, and what does the United States need to do to achieve it? Pathways to Exploration explores the case for advancing this endeavor, drawing on the history of rationales for human spaceflight, examining the attitudes of stakeholders and the public, and carefully assessing the technical and fiscal realities. This report recommends maintaining the long-term focus on Mars as the horizon goal for human space exploration. With this goal in mind, the report considers funding levels necessary to maintain a robust tempo of execution, current research and exploration projects and the time/resources needed to continue them, and international cooperation that could contribute to the achievement of spaceflight to Mars. According to Pathways to Exploration, a successful U.S. program would require sustained national commitment and a budget that increases by more than the rate of inflation. In reviving a U.S. human exploration program capable of answering the enduring questions about humanity's destiny beyond our tiny blue planet, the nation will need to grapple with the attitudinal and fiscal realities of the nation today while staying true to a small but crucial set of fundamental principles for the conduct of exploration of the endless frontier. The recommendations of Pathways to Exploration provide a clear map toward a human spaceflight program that inspires students and citizens by furthering human exploration and discovery, while taking into account the long-term commitment necessary to achieve this goal.
