Download or read book Orbital Debris written by National Research Council and published by National Academies Press. This book was released on 1995-07-07 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of space flight, the collision hazard in Earth orbit has increased as the number of artificial objects orbiting the Earth has grown. Spacecraft performing communications, navigation, scientific, and other missions now share Earth orbit with spent rocket bodies, nonfunctional spacecraft, fragments from spacecraft breakups, and other debris created as a byproduct of space operations. Orbital Debris examines the methods we can use to characterize orbital debris, estimates the magnitude of the debris population, and assesses the hazard that this population poses to spacecraft. Potential methods to protect spacecraft are explored. The report also takes a close look at the projected future growth in the debris population and evaluates approaches to reducing that growth. Orbital Debris offers clear recommendations for targeted research on the debris population, for methods to improve the protection of spacecraft, on methods to reduce the creation of debris in the future, and much more.

Download or read book Limiting Future Collision Risk to Spacecraft written by National Research Council and published by National Academies Press. This book was released on 2011-12-16 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Derelict satellites, equipment and other debris orbiting Earth (aka space junk) have been accumulating for many decades and could damage or even possibly destroy satellites and human spacecraft if they collide. During the past 50 years, various National Aeronautics and Space Administration (NASA) communities have contributed significantly to maturing meteoroid and orbital debris (MMOD) programs to their current state. Satellites have been redesigned to protect critical components from MMOD damage by moving critical components from exterior surfaces to deep inside a satellite's structure. Orbits are monitored and altered to minimize the risk of collision with tracked orbital debris. MMOD shielding added to the International Space Station (ISS) protects critical components and astronauts from potentially catastrophic damage that might result from smaller, untracked debris and meteoroid impacts. Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Program examines NASA's efforts to understand the meteoroid and orbital debris environment, identifies what NASA is and is not doing to mitigate the risks posed by this threat, and makes recommendations as to how they can improve their programs. While the report identified many positive aspects of NASA's MMOD programs and efforts including responsible use of resources, it recommends that the agency develop a formal strategic plan that provides the basis for prioritizing the allocation of funds and effort over various MMOD program needs. Other necessary steps include improvements in long-term modeling, better measurements, more regular updates of the debris environmental models, and other actions to better characterize the long-term evolution of the debris environment.

Download or read book History of On Orbit Satellite Fragmentations 14th Edition written by Nicholas L. Johnson and published by www.Militarybookshop.CompanyUK. This book was released on 2008-06 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Includes full color illustrations. Since the first serious satellite fragmentation occurred in June 1961 (which instantaneously increased the total Earth satellite population by more than 400%) the issue of space operations within the finite region of space around the Earth has been the subject of increasing interest and concern. The prolific satellite fragmentations of the 1970s and the marked increase in the number of fragmentations in the 1980s served to widen international research into the characteristics and consequences of such events. Continued events in all orbits in later years make definition and historical accounting of those events crucial to future research. Large, manned space stations and the growing number of operational robotic satellites demand a better understanding of the hazards of the dynamic Earth satellite population.

Along the way, you'll hear from the scientists who are working to ensure that outer space remains a safe place to travel and explore. If we don't tackle the space junk problem, it might be impossible to travel into space; it could even trap us on Earth.

Download or read book Dr Space Junk vs The Universe written by Alice Gorman and published by NewSouth. This book was released on 2019-04-01 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Going boldly forth as a pioneer in the fledgling field of space archaeology, Dr Alice Gorman (aka Dr Space Junk) turns the common perception of archaeology as an exploration of the ancient on its head. Her captivating inquiry into the most modern and daring of technologies spanning some 60 years — a mere speck in cosmic terms — takes the reader on a journey which captures the relics of space forays and uncovers the cultural value of detritus all too readily dismissed as junk. In this book, she takes a physical journey through the solar system and beyond, and a conceptual journey into human interactions with space. Her tools are artefacts, historical explorations, the occasional cocktail recipe, and the archaeologist’s eye applied not only to the past, but the present and future as well. Erudite and playful, Dr Space Junk reveals that space is not as empty as we might think. And that by looking up and studying space artefacts, we learn an awful lot about our own culture on earth. She makes us realise that objects from the past — the material culture produced by the Space Age and beyond — are so significant to us now because they remind us of what we might want to hold onto into the future. ‘As charming as it is expert, as gripping as it is surprising, Dr Space Junk vs The Universe deftly threads together the cosmic and the personal, the stupendousness of space with the lived experience of human beings down here.’ — Adam Roberts, author of Gradisil

Download or read book Achieving Science with CubeSats written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. 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.

Download or read book Satellite written by Doug Millard and published by Reaktion Books. This book was released on 2016-11-15 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Right now, above our heads—nearly imperceptible to us but hugely important to how we live—are thousands of man-made objects that we have sent into space. Ubiquitous but mysterious, satellites are the technological infrastructure of our globally connected world, helping us do everything from orient ourselves on a map to watch our favorite television shows. Yet we rarely ever think about them. In this book, Doug Millard pays overdue tribute to the stoic existence of the satellite, tracing its simultaneous pathways through the cold silence of space and the noisy turbulence of the past century. How satellites ever came to be is, in itself, a remarkable story. Telling an astonishing history of engineering experimentation and ingenuity, Millard shows how the Cold War space race made the earliest satellites—ones like Sputnik, Telstar, and Early Bird—household names. He describes how they evolved into cultural signifiers that represented not only our scientific capabilities but our capacity for imagination, our ability to broaden the scope of our vision to the farthest reaches. From there he follows the proliferation of satellites in the second half of the twentieth century, examining their many different forms, how they evolved, all the things they do, what they have enabled, and how they have influenced our popular culture. Ultimately, Millard asks what we can still expect, what sort of space age the satellite has initiated that is yet to be fully realized. Published in association with the Science Museum, London, this beautifully illustrated book will appeal to any fan of space exploration and technology.
