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 Lunar Meteoroid Impacts and How to Observe Them written by Brian Cudnik and published by Springer Science & Business Media. This book was released on 2009-12-04 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The face of the Moon we see today has been substantially etched by the effects of meteor impacts. Craters on the Moon are the result of ancient impacts with large meteorites - or small asteroid-like bodies - which produced both primary craters (where the meteorites hit) and secondary craters (where material hurled high above the surface crashed back down). Even some of the vast lunar "seas" - actually basalt plains from ancient volcanic eruptions - may have been the result of impacts that triggered lava outflows. The era of major impacts on the Moon may have passed, but lunar meteorites may well be the cause of what are known as Lunar Transient Phonomena ("LTP" or sometimes "TLP") flashes and puffs of gas or vaporized rock or dust that are observed on the Moon's surface. This book looks at the way the Moon has been shaped by meteorites, proposes lunar meteorites as the most likely cause of most LTPs and describes in practical detail how amateur astronomers can observe impacts on the Moon, past and current.

Download or read book Collision Earth written by Peter Grego and published by Blandford Press. This book was released on 1998 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: What's the likelihood of the impact on earth of debris from outer space? Even near misses can change our climate, while a major impact could be catastrophic, equivalent to that which caused the disappearance of the dinosaurs and the rise of mammalian mastery of the planet. In this fascinating survey of the great collisions and the dangerous close passes of recent and prehistoric times, you'll find detailed chronicles of the effect on our earth of comets, meteors, meteorites, meteor storms, shooting stars, cosmic famous fireballs, UFOs, and other phenomena.

Download or read book Meteor Showers and their Parent Comets written by Peter Jenniskens and published by Cambridge University Press. This book was released on 2006-09-14 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meteor Showers and their Parent Comets is a unique handbook for astronomers interested in observing meteor storms and outbursts. Spectacular displays of 'shooting stars' are created when the Earth's orbit crosses a meteoroid stream, as each meteoroid causes a bright light when it enters our atmosphere at high speed. Jenniskens, an active meteor storm chaser, explains how meteoroid streams originate from the decay of meteoroids, comets and asteroids, and how they cause meteor showers on Earth. He includes the findings of recent space missions to comets and asteroids, the risk of meteor impacts on Earth, and how meteor showers may have seeded the Earth with ingredients that made life possible. All known meteor showers are identified, accompanied by fascinating details on the most important showers and their parent comets. The book predicts when exceptional meteor showers will occur over the next fifty years, making it a valuable resource for both amateur and professional astronomers.

Available in PDF, EPUB and Kindle. Book excerpt: The natural space environment is characterized by many complex and subtle phenomena hostile to spacecraft. The effects of these phenomena impact spacecraft design, development, and operations. Space systems become increasingly susceptible to the space environment as use of composite materials and smaller, faster electronics increases. This trend makes an understanding of the natural space environment essential to accomplish overall mission objectives, especially in the current climate of better/cheaper/faster. Meteoroids are naturally occurring phenomena in the natural space environment. Orbital debris is manmade space litter accumulated in Earth orbit from the exploration of space. Descriptions are presented of orbital debris source, distribution, size, lifetime, and mitigation measures. This primer is one in a series of NASA Reference Publications currently being developed by the Electromagnetics and Aerospace Environments Branch, Systems Analysis and Integration Laboratory, Marshall Space Flight Center, National Aeronautics and Space Administration.

Download or read book Hazards Due to Comets and Asteroids written by Tom Gehrels and published by University of Arizona Press. This book was released on 1994 with total page 1340 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1993, the U.S. Department of Defense declassified information dealing with frequent explosions in the upper atmosphere caused by meteoric impact. It is estimated that impacts have occurred of a magnitude equivalent to the atomic bomb detonated at Hiroshima. Not all such space voyagers meet their end in the atmosphere, however; huge craters attest to the bombardment of earth over millions of years, and a major impact may have resulted in the extinction of dinosaurs. An impact in Siberia near the beginning of this century proves that such events are not confined to geologic time. Hazards Due to Comets and Asteroids marks a significant step in the attempt to come to grips with the threats posed by such phenomena. It brings together more than one hundred scientists from around the world, who draw on observational and theoretical research to focus on the technical problems related to all aspects of dealing with these hazards: searching for and identifying hazardous comets and asteroids; describing their statistics and characteristics; intercepting and altering the orbits of dangerous objects; and applying existent technologies—rocket boosters, rendezvous and soft-landing techniques, instrumentation—to such missions. The book considers defensive options for diverting or disrupting an approaching body, including solar sails, kinetic-energy impacts, nuclear explosives, robotic mass drivers, and various propulsion systems. A cataclysmic impact posing a threat to life on Earth is a possibility that tomorrow's technology is capable of averting. This book examines in depth the reality of the threat and proposes practical measures that can be initiated now should we ever need to deal with it.
