The amount of space debris is growing at an alarming rate, raising concern about its collision with operational spacecraft. This book analyzes the probability of such a collision when the orbits of two approaching objects are based on measurements with inherent errors. Many recent papers have dealt with the methodology of computing the collision probability in the encounter region, but they have assumed that the encounter is a flyby and is short-term, with the trajectories of the objects represented by straight lines. By contrast, Spacecraft Collision Probability, the outgrowth of the authors research during the past two decades, deals not only with those cases but also with important long-term cases in which objects spend protracted periods in the vicinity of each other. An extensive chapter is included on the International Space Station (ISS), to demonstrate how one would accurately gauge its probability of collision. The ISS is modeled according to its actual complex shape, component by componentenabling the detailed computation of a more realistic collision probability than one would obtain by the routine practice of modeling it as a sphere. In addition, the author developed Excel macros to obtain the numerical tables and graphical plots appearing in the book. That software is available on the Supporting Materials page of the AIAA Web site.

An increasing number of missions require spacecraft to fly in close proximity. Despite the technological advances that have made these types of missions increasingly possible there remains a limit to how accurately the trajectory of a spacecraft can be predicted. As such, one of the main risks to spacecraft in close proximity is the threat of a collision. Many methods exist for computing the probability of collision between spacecraft. These methods incorporate the uncertainty in predicting the spacecrafts motion when computing an estimate. The accuracy and required computation time of these methods very greatly. A poor estimate of collision risk will not only increase the likelihood of a collision occurring, it can also carry other negative consequences. One possible side effect is additional fuel being spent to reduce the threat of a collision which is estimated to be high but in reality is low. This thesis explores several methods for estimating spacecraft collision probability and addresses wether each can be used effectively in real time while the spacecraft are on-orbit.Each of the methods can be placed into one of three categories. The first category of methods do not directly estimate collision probability. Instead they place an upper limit on what the actual collision probability can be. The second category are methods which are capable of directly estimating collision probability over a time interval. The last category uses a common statistical analysis tool known as Monte Carlo to determine the probability of collision over an interval of time. This category also includes a novel method called Pseudo Monte Carlo. Each of the methods are compared and their accuracy are evaluated for a variety of orbit conditions.Finally, an algorithm is proposed in which the methods are arranged in a hierarchy so that those methods which can be computed quickest are calculated first. As the proposed algorithm progresses the methods become more costly to compute, but yield more accurate estimates of collision probability. The result from each method is compared to a threshold value. If it exceeds the limits determined by mission constraints, the algorithm computes a more accurate estimate by utilizing the next method in the series. If the threshold is not reached, it is assumed there is a tolerable collision risk and the algorithm is terminated. In this way the algorithm is capable of adapting to the level of collision probability, and can be sufficiently accurate without needless calculations being performed. This work shows that collision probability can be systematically estimated.

This volume is designed as an introductory text and reference book for graduate students, researchers and practitioners in the fields of astronomy, astrodynamics, satellite systems, space sciences and astrophysics. The purpose of the book is to emphasize the similarities between celestial mechanics and astrodynamics, and to present recent advances in these two fields so that the reader can understand the inter-relations and mutual influences. The juxtaposition of celestial mechanics and astrodynamics is a unique approach that is expected to be a refreshing attempt to discuss both the mechanics of space flight and the dynamics of celestial objects. “Celestial Mechanics and Astrodynamics: Theory and Practice” also presents the main challenges and future prospects for the two fields in an elaborate, comprehensive and rigorous manner. The book presents homogenous and fluent discussions of the key problems, rendering a portrayal of recent advances in the field together with some basic concepts and essential infrastructure in orbital mechanics. The text contains introductory material followed by a gradual development of ideas interweaved to yield a coherent presentation of advanced topics.

This book presents a comprehensive exploration of space debris from four essential perspectives: detection, early warning, protection, and mitigation. It begins with both ground-based and space-based detection technologies and systems, followed by an in-depth discussion on debris environment modeling, prediction principles, and early warning mechanisms. The book then addresses spacecraft shielding structures and protective materials, along with mission-level protection design. Finally, it covers mission planning strategies and active debris removal techniques for long-term mitigation. Policy frameworks, international regulatory efforts, and global collaboration initiatives are also examined to provide a complete context. This volume is ideal for undergraduate and graduate students, researchers, and engineers engaged in aerospace engineering, space safety, and orbital operations, offering both foundational theories and advanced methodologies.
