Book Description
For over half a century, an increasing number of satellites have fragmented in orbit, creating a large amount of hazardous orbital debris which threaten the safety of useful functioning satellites and space missions. This book discusses the theory behind these fragmentations followed by studies of actual cases.The book begins with a survey of satellite fragmentations in orbit and the consequent formation of orbital debris in chronological order. Next, the fundamental physical processes underlying satellite fragmentations are outlined and the methods of analyzing satellite fragmentations presented. The rest of the book presents analyses of the major satellite fragmentation events including accidental and intentional breakups, those due to explosions and collisions, as well as those belonging to the unknown category.

Book Description
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.

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 first edition of the History of On-orbit Satellite Fragmentations was published by Teledyne Brown Engineering in August 1984 under the sponsorship of the NASA Johnson Space Center and with the cooperation of the U.S. Air Force Space Command and the U.S. Army Ballistic Missile Command. The objective was to bring together information about the 75 satellites, which had, at that time, experienced noticeable breakups. This update encompasses all known satellite fragmentations and was first published by the NASA Johnson Space Center's Orbital Debris Program Office (ODPO). AI summary: The document provides a comprehensive overview of various space debris events and their characteristics, serving as a useful resource for those interested in the topic. It covers events from 1991 to 2022, involving satellites and rocket bodies from different countries, including Transit 5B-2, Elektron 1, OPS 4412 (Transit 9), Cosmos 44 R/B, OPS 4988 (GREB 6), OPS 4682 (Snapshot), and OPS 8480 (Transit 5B-6). The document includes information on the type of satellite or rocket body involved in each event, including details on its size, shape, and major appendages, as well as information on the attitude control of each object. The document provides a history of satellite aerodynamic events, including launch dates, breakup dates, reentry dates, and additional information for various satellites. The information is presented in a table format, with each row representing a different satellite or debris object. The table includes details such as the satellite name, international designator, launch date, breakup date, reentry date, debris cataloged, apogee, perigee, inclination, and additional information. The document also discusses the RORSAT program, which involved Soviet satellites with nuclear reactors that were ejected into a higher storage orbit, resulting in the venting of sodium-potassium coolant. The document provides a list of coolant objects cataloged as of May 2022. The document also discusses spurious associations with fragmentation events and the importance of conducting analyses with complete satellite element set data. Overall, the document provides a comprehensive overview of various space debris events and their impact on space exploration and satellite operations. It serves as a reminder of the need for continued research and development to address the challenges posed by space debris and other anomalies. This book is annotated by Nimble AI and includes a Foreword by Cincinnatus [AI] a variety of pithy, opinionated abstracts including scientific style, tldr, tldr one word, Explain It to Me Like I'm Five Years Old, and Action Items; tools for viewpoint diversity such as Dissents, Red Team Critiques, and MAGA Perspectives; and a recursive summary with synopsis.

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

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
Orbital motion is a vital subject which has engaged the greatest minds in mathematics and physics from Kepler to Einstein. It has gained in importance in the space age and touches every scientist in any field of space science. Still, there is almost a total dearth of books in this important field at the elementary and intermediate levels — at best a chapter in an undergraduate or graduate mechanics course.This book addresses that need, beginning with Kepler's laws of planetary motion followed by Newton's law of gravitation. Average and extremum values of dynamical variables are treated and the central force problem is formally discussed. The planetary problem in Cartesian and complex coordinates is tackled and examples of Keplerian motion in the solar system are also considered. The final part of the book is devoted to the motion of artificial Earth satellites and the modifications of their orbits by perturbing forces of various kinds.
