The distribution of chlorine was considered as a possible marker of processes that played a significant role at different stages of the evolution of the Martian climate. It was found that the vicinity and base of the Mount Sharp sedimentary mountain with river and lake deposits, as well as higher and younger areas that correspond to the transition to hydrated sulfate deposits, can have a uniform distribution of chlorine by depth (up to 50 cm). At the same time, areas located between these two groups, where hematite and clay deposits were found, show a sharp heterogeneity in the distribution of chlorine, with higher chlorine concentrations at the surface itself. This may indicate that in the first case, one source of chlorine transfer, possibly related to water activity, was dominant, while in the second case, there may have been several such sources.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145941551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With this approach, specialized models of individual dynamic, physical, and chemical processes in the water oceans of these cosmic objects can be integrated into a single whole, i.e., this approach takes into account their complexity and mutual influence, inducing significant mutual changes. A heterogeneous continuum model has been developed for multilayer nonperfect media with the methods of multivelocity mechanics and nonequilibrium thermodynamics, accounting for the asymmetry of the pressure tensor of phase media, equilibrium chemical reactions, phase transitions, and heat- and mass-transfer processes. The generalized Stefan–Maxwell relations for multiphase mixtures, which are a system of equations of motion of individual phases with genuine inertial forces, have been first derived in terms of thermodynamics. We propose a thermodynamic technique that allows obtaining a number of algebraic relationships for transport coefficients associated with diffusion–thermal processes in a multiphase medium. The developed approach is primarily intended for mathematical modeling of the water ocean and ice crust of Saturn’s moon Enceladus, beneath the surface of which one could possibly search for extraterrestrial life in the Solar System.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145941552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A vast majority of these bodies are near-Earth asteroids (NEAs). Based on the analysis of statistical characteristics of the NEA population, it has been shown that, on a practically significant time scale (~1000 years), the main danger is posed by NEAs of size 10–50 m, since they collide with the Earth more often than larger bodies. Consequently, the main practically significant task of counteracting the ACH is to detect such decameter-sized NEAs. They can can only be detected in close proximity, at distances of less than 0.05 AU from the Earth. The detection timescale is short, measured in hours (up to one day). This problem is still far from being solved. Larger bodies can be detected with more success. They can be detected at greater distances and, accordingly, the detection timescale is much longer. A rational approach to detecting NEAs has been proposed, the essence of which is that it is necessary to accelerate the development of instruments and methods to detect NEAs in the near zone. This is the most immediate challenge. At the same time, it is also necessary to continue work on searching for larger bodies in the far zone. These detection strategies require different technical means.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"59 7","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145729995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Schomberger A crater is located in the south polar region. This crater is the smallest of the three under consideration (its diameter is 31 km) and the youngest (it dates back to the Copernican period). There is almost no regolith on its floor and inner slopes. In the study areas on its floor, small craters exhibit no lobate rims, which is evidently caused by almost complete absence of regolith there. The Rozhdestvenskiy K crater is located in the north polar region. It is medium in size among the three considered (its diameter is 42 km) and medium in age (it dates back to the Eratosthenian period). On the floor of this crater, the regolith is rather thick; and there are small craters with lobate rims there, which is considered a sign of a rather high amount of water ice in the target material. However, the measurements with the Lunar Exploration Neutron Detector (LEND) did not detect any increased content of hydrogen associated with this crater. The Lovelace crater is also located in the north polar region. It is the largest of the three under consideration (its diameter is 54 km) and the oldest (it dates back to the Late Imbrian period). On the floor of this crater, the regolith is quite thick; and craters with lobate rims are observed there, which is considered an indication of a rather high amount of water ice in the target material.

Key chaos indicators were calculated, including Lyapunov exponents, Poincaré sections, and fractal dimensions, to quantify the system’s dynamic behavior. For the Sun–Earth system, the estimated Lyapunov exponent is on the order of 10–6 per year, while the Earth–Moon system exhibits stronger chaotic characteristics with a Lyapunov exponent of approximately 10–4 per year, corresponding to an orbital divergence time scale shorter than million years. Poincaré section analysis and the box-counting method reveal that the fractal dimension of the Earth–Moon subsystem is 1.768, indicating the existence of a mixed phase space where KAM tori and chaotic resonance layers coexist. Comparison with an idealized two-body model validates the numerical accuracy and highlights the destabilizing effect of solar perturbations. Furthermore, the influence of other planets is quantitatively proven to be negligible. Long-term stability analysis (over 104 years) shows that variations in eccentricity and the Earth–Moon distance remain within limited ranges, with tidal dissipation acting as a stabilizing mechanism. The drift in energy and angular momentum is minimal, verifying the reliability of the numerical results. Multi-scale entropy analysis further supports the conclusion of weak chaos, showing low overall complexity but dynamic structures that vary over time.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"59 7","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145510648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
