Investigation of the characteristics of the near-moon system for hitting asteroids

Abstract

The paper presents an analysis of the current state of research into the problems of the control of the asteroid hazard, which has shown the need to create a multilevel system for hitting asteroids. Mathematical models and characteristics of the near-moon system of damage to asteroids are developed and investigated. For a basic system consisting of a single interceptor spacecraft (ISC), estimates of the probabilities of asteroids are given, on the basis of which conclusions are made about the potential effectiveness of this system, and the main directions for further research are indicated. An original dynamic model for planning the application of the near-moon system of hitting asteroids by the ISC group is proposed. Approaches to the solution of problems of modeling and planning the application of this group based on the combined use of the mathematical apparatus of the modern theory of optimal control and operations research are analyzed and substantiated. The analysis also showed that the model-algorithmic support, developed for the present time, can be used not only for the near-moon but also for other levels of the proposed system for protecting the Earth from asteroids.
