Free particle modelling of hypervelocity asteroid collisions with the Earth

“…The simulations were performed using updated proper Hydrocode of the Free Particles Method with Gravitation prepared for solving the Shock-Wave Physics problems. This hydrocode has been comprehensively verified, calibrated, and positively validated during the modeling of many cases of deformable celestial body collisions, as shown in publications [1] and [17][18][19][20][21][22][23][24]. As spacecraft warhead operations are most effective at close range, the final part of the Future Planetary Defense System (FPDS) mission will start at the end of precision deep space navigation phase.…”

“…The spacecraft can operate in the four planes with common equinox vector. For the initial orbits calculations, and visualizations we used Asterank Portal prepared by Ian Webster [22]. Four planes deviate from the fundamental ecliptic plane: the first plane by ecliptic latitude is b = 0 0 (Ring of Spacecraft b0), the second plane by ecliptic latitude is b = 45 0 (Ring of Spacecraft b45), the third plane by ecliptic latitude is b = 90 0 (Ring of Spacecraft b90), and the fourth plane by ecliptic latitude is b = -45 0 (Ring of Spacecraft b-45) as seen in Figures 18-21 [22].…”

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 the 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 the Potentially Hazardous Objects (PHOs) to orbits safe for the Earth or destroy them. This concept's first task is to find, prepare and use dynamic three-dimensional models of celestial bodies' motion 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, selected methods of fighting 100 m and 140 m diameter asteroids. The order of the article is as follows. The first part of the article presents an architecture and FPDS' modus operandi. Preliminary design and development of FPDS' space missions, including navigation, mission dynamics simulation, is prepared using an open-source space mission analysis and design tool. E.g., Asterank and Trajectory Browser or GMAT are presented in the second part. 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 FPDS spacecraft's warhead contact interaction on the small celestial body. The authors formulated the Main Planetary Defense Problem (MPDP) in this paper. The proposition of this problem solving has been realized by preparing its concepts, architecture, and modus operandi of the FPDS mission. Finally, a series of realistic simulations were made using hydrocode to deflect or destroy dangerous asteroids. The summary and conclusions can be found in the fourth part of the article.
