Abstract
The article is devoted to the preliminary concept of the Future Planetary Defense System (FPDS) emphasizing astroballistics. This paper is intended to support international efforts to improve the planetary security of Earth. The work covers three areas of knowledge: astronautics, astrodynamics, and astroballistics. The most important part of the presented article is dynamic, contact combat modeling against small, deformable celestial bodies. For these purposes, the original, proprietary hydrocode of the free particle method (HEFPM-G) with gravity was used. The main aim of combat is to redirect potentially hazardous objects (PHOs) to orbits safe for Earth or destroy them. This concept’s first task is to find, prepare, and use dynamic three-dimensional models of the motion of celestial bodies and spacecraft or human-crewed spaceships in the solar system’s relativistic frame. The second task is to prepare the FPDS’ architecture and computer simulation space missions’ initial concepts in the internal part of the solar system. The third and main task covers simulating, using hydrocodes, and selected methods of fighting 100 m diameter rock material asteroids.
Highlights
In this paper, an original proper hydrocode of free particles method (HEFPM-G) with gravitation [1] was applied to simulate the terminal astroballistics problems with three methods of contact deflection of virtual potential hazardous asteroids (PHAs)
Synchronization cannot take place along beams of photons running near large masses, for example, to the Sun or Jupiter, which is a problem related to bending light beams in gravitational fields
We focused on the outer circular ring with a radius of 1.25 AU with the initial number of spacecraft for modeling ranging from 24 methods to 72
Summary
An original proper hydrocode of free particles method (HEFPM-G) with gravitation [1] was applied to simulate the terminal astroballistics problems with three methods of contact deflection of virtual potential hazardous asteroids (PHAs). This paper’s primary goal was to simulate, as realistically as possible, the impulse interactions on small, dangerous space bodies This is the decisive and final phase of the original project of the FPDS Space Mission. From the mission navigator’s point of view, it is necessary to start the navigation in an interesting area of the solar system space, where the beginning of the threat to Earth has been detected This procedure requires the systematic use of the computational methods of astronautics and astrodynamics to model and simulate motion until the spacecraft’s close encounter with the PHO. The third part of the article is devoted to computer hydrocodes (HEFPM-G) and the modeling and simulation of asteroid–asteroid collision, laser radiation effects on an asteroid, and the FPDS spacecraft’s warhead contact interaction with the small celestial body. An abridged version of the description of the FPDS network-centric architecture (FPDS is distributed in the inner part of the solar system) is presented [6]
