Available in PDF, EPUB and Kindle. Book excerpt: This testimony discusses management challenges and program risks that the National Aeronautics and Space Administration (NASA) faces in maintaining a skilled workforce, controlling costs, and providing effective oversight for important projects. NASA is taking on a major transformation aimed at eliminating stovepipes; becoming more integrated and results oriented; and reducing risks while working more economically, efficiently, and effectively. Successfully addressing each of four challenges will be critical for NASA in making sure that it is equipped to achieve its vision for the future. The first--strengthening human capital--will require a concerted and sustained effort by NASA's leadership to commit to change; ensure an appropriate mix of employees to meet future business needs; implement effective approaches for acquiring, developing, and retaining talent; develop and retain talent; and create a results-oriented culture. The remaining challenges facing NASA--controlling International Space Station costs; implementing a faster, better, cheaper approach to space exploration; and correcting weaknesses in contract management--are equally important. Without better oversight and management over its most important programs and acquisitions, NASA's transformation stands to lose credibility and support among its partners in industry, the international community, and academia as well as the support of Congress.

Download or read book Science Advice to NASA written by Joseph K. Alexander and published by National Aeronautics and Space Administration Office of Communications NASA History Division. This book was released on 2017 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book documents highlights of NASA's interactions with outside scientific advisors over the agency's full lifetime and draws lessons from that history for research managers, decision makers, and scientists.The book is divided into three parts--the first two being focused on history and the third on synthesis and analysis. Part 1 briefly examines early forerunner activities at NACA and in the decade leading up to NASA's formation, and it then considers NASA's use of outside advice during its first three decades. Part 2 picks up the story in 1988 and follows it up to 2016. Part 3 examines a sampling of case studies, discusses recurring characteristics of notably successful advisory activities, and provides a glimpse at what past experience might imply for the future of scientific advice at NASA. The last two chapters provide big-picture summaries of themes that have emerged from earlier discussions.

This book was released on 2016-11-06 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space-based observations have transformed our understanding of Earth, its environment, the solar system and the universe at large. During past decades, driven by increasingly advanced science questions, space observatories have become more sophisticated and more complex, with costs often growing to billions of dollars. Although these kinds of ever-more-sophisticated missions will continue into the future, small satellites, ranging in mass between 500 kg to 0.1 kg, are gaining momentum as an additional means to address targeted science questions in a rapid, and possibly more affordable, manner. Within the category of small satellites, CubeSats have emerged as a space-platform defined in terms of (10 cm x 10 cm x 10 cm)- sized cubic units of approximately 1.3 kg each called "U's." Historically, CubeSats were developed as training projects to expose students to the challenges of real-world engineering practices and system design. Yet, their use has rapidly spread within academia, industry, and government agencies both nationally and internationally. In particular, CubeSats have caught the attention of parts of the U.S. space science community, which sees this platform, despite its inherent constraints, as a way to affordably access space and perform unique measurements of scientific value. The first science results from such CubeSats have only recently become available; however, questions remain regarding the scientific potential and technological promise of CubeSats in the future. Achieving Science with CubeSats reviews the current state of the scientific potential and technological promise of CubeSats. This report focuses on the platform's promise to obtain high- priority science data, as defined in recent decadal surveys in astronomy and astrophysics, Earth science and applications from space, planetary science, and solar and space physics (heliophysics); the science priorities identified in the 2014 NASA Science Plan; and the potential for CubeSats to advance biology and microgravity research. It provides a list of sample science goals for CubeSats, many of which address targeted science, often in coordination with other spacecraft, or use "sacrificial," or high-risk, orbits that lead to the demise of the satellite after critical data have been collected. Other goals relate to the use of CubeSats as constellations or swarms deploying tens to hundreds of CubeSats that function as one distributed array of measurements.

This book was released on 2000-05-12 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote observations of Earth from space serve an extraordinarily broad range of purposes, resulting in extraordinary demands on those at the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and elsewhere who must decide how to execute them. In research, Earth observations promise large volumes of data to a variety of disciplines with differing needs for measurement type, simultaneity, continuity, and long-term instrument stability. Operational needs, such as weather forecasting, add a distinct set of requirements for continual and highly reliable monitoring of global conditions. The Role of Small Satellites in NASA and NOAA Earth Observation Programs confronts these diverse requirements and assesses how they might be met by small satellites. In the past, the preferred architecture for most NASA and NOAA missions was a single large spacecraft platform containing a sophisticated suite of instruments. But the recognition in other areas of space research that cost-effectiveness, flexibility, and robustness may be enhanced by using small spacecraft has raised questions about this philosophy of Earth observation. For example, NASA has already abandoned its original plan for a follow-on series of major platforms in its Earth Observing System. This study finds that small spacecraft can play an important role in Earth observation programs, providing to this field some of the expected benefits that are normally associated with such programs, such as rapid development and lower individual mission cost. It also identifies some of the programmatic and technical challenges associated with a mission composed of small spacecraft, as well as reasons why more traditional, larger platforms might still be preferred. The reasonable conclusion is that a systems-level examination is required to determine the optimum architecture for a given scientific and/or operational objective. The implied new challenge is for NASA and NOAA to find intra- and interagency planning mechanisms that can achieve the most appropriate and cost-effective balance among their various requirements.

Book excerpt: "The National Aeronautics and Space Administration (NASA) is in the midst of many changes and one of the most challenging periods in its history. The space shuttle is slated to retire this year, the International Space Station nears completion but remains underutilized, and a new means of human space flight is under development. Most recently, the administration has proposed a new direction for NASA. Amid all this potential change, GAO was asked to review the key issues facing NASA. This testimony focuses on four areas: 1) retiring the space shuttle; 2) utilizing and sustaining the International Space Station; 3) continuing difficulty developing large-scale systems, including the next generation of human spaceflight systems; and 4) continuing weaknesses in financial management and information technology systems. In preparing this statement, GAO relied on completed work. To address some of these challenges, GAO has recommended that NASA: provide greater information on shuttle retirement costs to Congress, take actions aimed at more effective use of the station research facilities, develop business cases for acquisition programs, and improve financial and IT management. NASA concurred with GAO's International Space Station recommendations, and has improved some budgeting and management practices in response."--Highlights.

Available in PDF, EPUB and Kindle. Book excerpt: This book is in full-color - other editions may be in grayscale (non-color). The hardback version is ISBN 9781680920512 and the paperback version is ISBN 9781680920505. The NASA Space Flight Program and Project Management Handbook (NASA/SP-2014-3705) is the companion document to NPR 7120.5E and represents the accumulation of knowledge NASA gleaned on managing program and projects coming out of NASA's human, robotic, and scientific missions of the last decade. At the end of the historic Shuttle program, the United States entered a new era that includes commercial missions to low-earth orbit as well as new multi-national exploration missions deeper into space. This handbook is a codification of the "corporate knowledge" for existing and future NASA space flight programs and projects. These practices have evolved as a function of NASA's core values on safety, integrity, team work, and excellence, and may also prove a resource for other agencies, the private sector, and academia. The knowledge gained from the victories and defeats of that era, including the checks and balances and initiatives to better control cost and risk, provides a foundation to launch us into an exciting and healthy space program of the future.
Download or read book Spaceflight Associated Neuro Ocular Syndrome written by Andrew G. Lee and published by Academic Press. This book was released on 2022-07-16 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prolonged microgravity exposure during long-duration spaceflight (LDSF) produces unusual physiologic and pathologic neuro-ophthalmic findings in astronauts. These microgravity-associated findings collectively define the Spaceflight Associated Neuro-ocular Syndrome (SANS). In this book, the editors compare and contrast prior published work on SANS by the National Aeronautics and Space Administration’s (NASA) Space Medicine Operations Division with retrospective and prospective studies from other research groups. The book describes the possible mechanisms and potential etiologies for SANS, and provides an update and review on the clinical manifestations of SANS including: unilateral and bilateral optic disc edema, globe flattening, choroidal and retinal folds, hyperopic refractive error shifts, and focal areas of ischemic retina (i.e., cotton wool spots). The ocular imaging findings (e.g., retinal nerve fiber layer, optic disc, and choroidal changes on optical coherence tomography) of SANS is also described, including the intraorbital and intracranial findings on orbital ultrasound and magnetic resonance imaging. The knowledge gaps for in-flight and terrestrial human research including potential countermeasures for future stud is also explored, including reports on the in-flight and terrestrial human and animal research being investigated by NASA and its partners to study SANS both prospectively and longitudinally and in preparation for future long duration manned missions to space including the moon, the asteroid belt, or Mars. We think this is a unique topic and hope that NASA and its research partners continue to study SANS in preparation for future longer duration manned space missions. Written in an easy-to-read manner, the book adopts a translational approach and explores the science and the clinical manifestations of Space flight associated neuro-ocular syndrome. It is also multi-disciplinary and suitable for both clinicians and researchers in ophthalmology, neurology, and aerospace medicine interested in SANS SANS is a unique space flight disorder that has no terrestrial equivalent. The book involves contributions from international experts across multiple disciplines to tackle the problem of SANS Summarizes and reviews the current findings of SANS, including possible mechanisms and potential etiologies, clinical manifestations, current reports on the in-flight and terrestrial human and animal research, and ocular imaging findings
