Future of U.S. Human Spaceflight by Derek A. Warren,Bridget D. Conway Pdf
Space operations are among the most demanding and unforgiving pursuits ever undertaken by humans and will become all the more difficult when means do not match aspirations. Will we leave the close proximity of low-Earth orbit, where astronauts have circled since 1972, and explore the solar system, charting a path for the eventual expansion of human civilisation into space? If so, how will we ensure that our exploration delivers the greatest benefit to the nation? Can we explore with reasonable assurances of human safety? Can the nation marshal the resources to embark on the mission? This book explores the nations important decisions on the future of human spaceflight.

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.
The History of Human Space Flight by Ted Spitzmiller Pdf
Military Writers Society of America Awards, Gold Medal for History Highlighting men and women across the globe who have dedicated themselves to pushing the limits of space exploration, this book surveys the programs, technological advancements, medical equipment, and automated systems that have made space travel possible. Beginning with the invention of balloons that lifted early explorers into the stratosphere, Ted Spitzmiller describes how humans first came to employ lifting gasses such as hydrogen and helium. He traces the influence of science fiction writers on the development of rocket science, looks at the role of rocket societies in the early twentieth century, and discusses the use of rockets in World War II warfare. Spitzmiller considers the engineering and space medicine advances that finally enabled humans to fly beyond the earth's atmosphere during the space race between the United States and the Soviet Union. He recreates the excitement felt around the world as Yuri Gagarin and John Glenn completed their first orbital flights. He recounts triumphs and tragedies, such as Neil Armstrong's "one small step" and the Challenger and Columbia disasters. The story continues with the development of the International Space Station, NASA's interest in asteroids and Mars, and the emergence of China as a major player in the space arena. Spitzmiller shows the impact of space flight on human history and speculates on the future of exploration beyond our current understandings of physics and the known boundaries of time and space.

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.

Seeking a Human Spaceflight Program by Human Spaceflight Human Spaceflight Plans Committee Pdf
The U.S. human spaceflight program appears to be on an unsustainable trajectory. It is perpetuating the perilous practice of pursuing goals that do not match allocated resources. Space operations are among the most demanding and unforgiving pursuits ever undertaken by humans. It really is rocket science. Space operations become all the more difficult when means do not match aspirations. Such is the case today. The nation is facing important decisions on the future of human spaceflight. Will we leave the close proximity of low- Earth orbit, where astronauts have circled since 1972, and explore the solar system, charting a path for the eventual expansion of human civilization into space? If so, how will we ensure that our exploration delivers the greatest benefit to the nation? Can we explore with reasonable assurances of human safety? Can the nation marshal the resources to embark on the mission? Whatever space program is ultimately selected, it must be matched with the resources needed for its execution. How can we marshal the necessary resources? There are actually more options available today than in 1961, when President Kennedy challenged the nation to "commit itself to the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." First, space exploration has become a global enterprise. Many nations have aspirations in space, and the combined annual budgets of their space programs are comparable to NASA's. If the United States is willing to lead a global program of exploration, sharing both the burden and benefit of space exploration in a meaningful way, significant accomplishments could follow. Actively engaging international partners in a manner adapted to today's multi-polar world could strengthen geopolitical relationships, leverage global financial and technical resources, and enhance the exploration enterprise. Second, there is now a burgeoning commercial space industry. If we craft a space architecture to provide opportunities to this industry, there is the potential-not without risk-that the costs to the government would be reduced. Finally, we are also more experienced than in 1961, and able to build on that experience as we design an exploration program. If, after designing cleverly, building alliances with partners, and engaging commercial providers, the nation cannot afford to fund the effort to pursue the goals it would like to embrace, it should accept the disappointment of setting lesser goals. Can we explore with reasonable assurances of human safety? Human space travel has many benefits, but it is an inherently dangerous endeavor. Human safety can never be absolutely assured, but throughout this report, safety is treated as a sine qua non. It is not discussed in extensive detail because any concepts falling short in human safety have simply been eliminated from consideration. How will we explore to deliver the greatest benefit to the nation? Planning for a human spaceflight program should begin with a choice about its goals-rather than a choice of possible destinations. Destinations should derive from goals, and alternative architectures may be weighed against those goals. There is now a strong consensus in the United States that the next step in human spaceflight is to travel beyond low-Earth orbit. This should carry important benefits to society, including: driving technological innovation; developing commercial industries and important national capabilities; and contributing to our expertise in further exploration. Human exploration can contribute appropriately to the expansion of scientific knowledge, particularly in areas such as field geology, and it is in the interest of both science and human spaceflight that a credible and well-rationalized strategy of coordination between them be developed. Crucially, human spaceflight objectives should broadly align with key national objectives.
Space technology has an important role to play in shaping a sustainable future, employing both human and robotic spaceflight capabilities. But the U.S. civil space program focuses the majority of its resources on the traditional paradigm of sending humans to increasingly distant targets (the Moon, Mars, and beyond). Rather than picking the destinations first and figuring out the goals later, the book suggests that NASA’s spaceflight programs should primarily target the creation of advanced capabilities, especially space infrastructure in the Earth-Moon system, and facilitate a greater role for the commercial sector in this endeavor. This will bring direct benefits to Earth more quickly and at the same time enable steady progress in the exploration and development of the solar system. The narrative begins by examining space in the context of today’s globalized world. Globalization has been a good news/bad news story, and space technology has been an important factor in this process. New wealth and international collaboration have been generated, but so have new problems and old problems have accelerated and spread. If we make the right choices, space development can do more to provide solutions in the decades ahead. The work of noted space futurists of the Cold War era is reviewed, with particular attention to the question: Why have things turned out differently from what most experts predicted and most advocates expected? The NASA exploration program finds itself locked into the “Von Braun paradigm” of the 1950s, which focuses on human spaceflight to the Moon and Mars without adequately explaining the reasons for doing it. This situation is not well suited to the political, economic, and societal environment of the 21st century. At a time when long-term strategic thinking is needed to address enduring global issues, many forces drive us to short-term thinking. The most significant of these forces for the nation’s top decision-makers come from the election cycle, the budget cycle, and the news cycle. Their effects on the presidency, the Congress, and the bureaucracy are examined using examples from recent history and current practices. The emphasis is on the need to change the incentive structure to promote long-term thinking since big technology projects have multi-decade life cycles and are aimed at problems that are national and global in scope. This shift in thinking leads to a revised rationale for spaceflight for the coming decades that is more directly tied to societal needs and ambitions. Space development will require more resources than NASA—or even all of the world’s civilian space agencies combined—can devote to the effort. Partnership with the commercial sector will be essential. Will space commerce be the stimulus for moving out into the solar system? If so, will it contribute to improvement of life back on Earth at the same time? Space commerce is growing fast, but is still small compared to other major global industries. Possibilities and pitfalls are discussed, along with examples of the checkered history of public and private sector attempts to promote space commerce. Making wise choices that have implications lasting decades is a daunting challenge, even when there’s broad agreement on a course of action. The book includes a chapter that warns: be careful what you wish for. Real-world examples (including the space shuttle and space station) demonstrate the difficulties of long-term strategic planning, and two futuristic thought experiments provide further illustration. The chapter concludes by demonstrating the long-term repercussions of poor choices, citing a current problem that has proven hard to fix despite widespread recognition that it needs fixing: export control for space technologies. If 21st century reality is driving us toward a course of action different from that of the Apollo/Cold War era, what should it look like, and what rationale should drive it?

Human Spaceflight lays out a new model for the future of humans in space, where robotic technologies extend human presence beyond the solar system. Louis Friedman argues for settlement of Mars, serving as a base for humans to explore the rest of the universe with an expanding arsenal of technology.

Recapturing a Future for Space Exploration by National Research Council,Division on Engineering and Physical Sciences,Aeronautics and Space Engineering Board,Space Studies Board,Committee for the Decadal Survey on Biological and Physical Sciences in Space Pdf
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.
Beyond the International Space Station: The Future of Human Spaceflight by Michael J Rycroft Pdf
Y. Fujimori, Symposium Programme Committee Chair, and Faculty Member, International Space University e-mail: fujimori@isu. isunet. edu M. Rycroft, Faculty Member, International Space University e-mail: rycroft@isu. isunet. edu Building on the foundations provided by the International Space Station, now partially constructed and already in use in low Earth orbit, what will be the future directions of human spaceflight? This was the key question discussed from many viewpoints - technical, entrepreneurial, governmental, legal - at the seventh Annual Symposium held in Strasbourg, France, early in June 2002. Many ideas on the "whys" and the "hows" of our future exploration of the final frontier were put forward in a stimulating environment. The unique perspective of the International Space University (ISU) - namely an interdisciplinary, international and intercultural perspective - enhanced both the presentations and the discussions. More than 150 people attended the Symposium, including the current members of the Master of Space Studies class who are attending an 11 month course at ISU. They are young professionals and postgraduate students who develop in-depth some part of the broad Symposium theme in their parallel Team Projects. Their final reports will be completed at the end of July 2002, and will be published independently. 1 Beyond the ISS: The Future of Human Spaceflight Keynote Address: A Summary The Need for a New Vision E.

From its beginnings, NASA was convinced that its real mission was to create the opportunity for a much different and better society on Earth, namely through human space flight. Pursuit of such a goal has led the agency to persist in certain activities even when they conflict with the wishes of Congress and the President. Recent changes in the international environment, changes that began well before September 11, 2001, have brought the military back into the field of human space flight, a situation that holds certain hazards for NASA since the military is more powerful politically. Dramatic changes could be in store, changes that could severely damage NASA's capacity for continuing what it sees as its primary objective. While most analyses see the agency as riddled with incompetence, Handberg argues that NASA's troubles are a product of its internal values. He begins with an historical overview of the major themes in NASA's history, followed by chapters on specific areas of concentration, such as the space station, space transportation, space science, and internal reforms. He also discusses the long-term future of the agency and human space flight in general, both domestically and internationally.
