“…However, even in the Earth layer of FPDS, the amount of necessary relativistic corrections for FPDS’ spacecraft clocks can be estimated (e.g., from the global positioning system (GPS) system satellite clocks in orbit around Earth). The next step is modeling the FPDS synchronization events as a coordination of the joint operation of the entire future planetary defense system problem and planetary protection [ 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 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.

“…Technological ones ("technosignatures"), i.e., communicative signals or artifacts in the broad sense (Wright 2021), are sought as proxies for extant or extinct intelligent, technology-capable life. Currently, both the search for microbial life (Profitiliotis 2021a) and the search for intelligent, technology-capable life (Profitiliotis 2021b) suffer from similar policy challenges, particularly related to independent private space activities: problems of jurisdiction and enforceability of corresponding measures.…”

The scientific search for extraterrestrial life mainly consists of looking for evidence of current and past microbial life and intelligent, technology-capable life. The space industry appears to have entered an era of “NewSpace” activities that are no longer conducted exclusively by the traditional state space powers. Instead, emerging space actors, both public and private, have commenced searches for extraterrestrial life. The likelihood of successfully discovering extraterrestrial life only increases when considering an unintentional discovery resulting from the various other space-related activities pursued by NewSpace actors. Unfortunately, the relevant policy landscape is plagued with significant gaps. Anticipatory diplomacy, that is, a model for diplomacy that seeks to act today to address the challenges of the future, might be appropriate for governing those science-related global activities and for encouraging cooperation among varying actors. This policy memo offers the United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS) suggestions on how to practically implement anticipatory diplomacy in the scientific endeavor of the search for extraterrestrial life by means of four proactive policies: harmonization of pre-discovery measures in national space laws, encouragement of international R&D partnerships among public and private actors, a public registry of activities with the potential to detect extraterrestrial life, and an appropriate interdisciplinary UNCOPUOS Working Group. The overall recommendation is to start with establishing the proposed UNCOPUOS Working Group and then to task it with evaluating if and how to implement the other three proactive policies.
