Book Description
When the first sputnik was launched and the space era began, few gave thought to the possible negative impact of putting satellites into orbit. In fact, man's space activity has led to the formation of a new media named "space debris," i.e. man-made objects and their fragments launched into space, currently inactive and no longer serving any useful purpose. Space Debris: Hazard Evaluation and Mitigation will appeal to readers unfamiliar with the issues, as well as experts and designers. It introduces concepts behind the problems of space ecology. The volume features actual data on the space debris environment; new mathematical models for space debris evolution, production and self-production; description of the existing software and concepts for shield design. The author also reviews methods of collision risk assessment, including the attitudes and inclinations of orbits, collision hazard evaluation and suggestions for preventative measures.

Book Description
The future evolution of the debris environment will be forecast on the basis of traffic models and possible hazard mitigation practices. The text shows how large trackable objects will have re-entry pinpointed and predictions made on related risk assessment for possible ground impact. Models will also be described for meteoroids which are also a prevailing risk.

Book Description
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.

Book Description
The hazard to space vehicles from natural space debris was explored. A survey of the available information pertinent to this problem is presented. The conclusion reached is that a definite hazard exists but that it can only be poorly assessed on the basis of present information. The need for direct measurement of this hazard is obvious, and some of the problems involved in making these direct measurements have been explored. (Author).

Book Description
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.

Book Description
An important concern of USSPACECOM has been developing a policy to reduce orbital debris, including ensuring proper spacecraft end-of-life disposal to minimize the number of spacecraft left on mission orbit beyond their useful lifetimes. This paper provides insight to the pertinent issues related to space debris and spacecraft disposal in addition to a detailed analysis of debris hazards for the Global Positioning System (GPS) family of spacecraft as outlined by M.E. Sorge. Results of the analysis show that inactive GPS satellites pose the most significant hazard to the GPS constellation of all space debris of large size, thus reaffirming recent U.S. space policy mandating deorbiting for all GPS satellites deemed non-mission capable. Additional analysis is recommended to explore collision probabilities for medium sized debris, since this category is also capable of disabling GPS satellites.
