It is shown that the temperature increase in the Northern Hemisphere began about 20 000 years ago due to volcanic events that occurred at that time, as well as in connection with the presence of a surplus of solar energy in this area of the planet, caused by the parameters of the Earth’s orbit: the inclination of the rotation axis, eccentricity, and precession angle. The surplus of thermal energy in the Northern Hemisphere has been preserved since then until the present day and will continue for at least 3000 years, after which the next period of glaciation will begin. Similar data are given for the Southern Hemisphere. It is shown that the melting of northern glaciers has been spread over many millennia due to the high heat of ice fusion and a pronounced phase transition. During melting, thermal energy is spent on the destruction of the ice crystal lattice, and the melt temperature does not increase. During freezing, the reverse process occurs: the energy released during ice crystallization prevents the temperature from decreasing. This process also occurs at a constant temperature. The heat-stabilizing properties of ice have manifested themselves in the form of “temperature shelves” on the graphs of the dependence of the average annual temperature on time, constructed based on the results of the analysis of ice cores obtained in the Southern Hemisphere at the Vostok station and in the Northern Hemisphere in central Greenland. At present, ice reserves in the Northern Hemisphere are coming to an end. Accordingly, the ability of glaciers to stabilize temperature is decreasing. As a result, the frequency and power of natural disasters in the world is growing. The problem of preserving the existing climate is becoming urgent. There is less and less time left for preparing and implementing measures to counteract climate change. Decarbonization cannot resist the ongoing process of destruction of the unique mechanism of natural climate stabilization. It is necessary to look for other ways to solve the problem of preserving the current climate. Among them, on the one hand, various methods of increasing albedo can be considered, and on the other hand, methods of reducing the permeability of the atmosphere by spraying special chemicals with short periods of complete decomposition in the upper layers of the atmosphere over certain areas.</p>","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"59 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438709","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 orbital evolution of the Neptune–Triton system due to tidal dissipation can be approximately determined from astrometrically observed positions of Triton over an extended period of time by using an accurate model of the orbital motion. The estimated accuracy of the Triton dynamical model we built and updated fit all the astrometric data. Based on the most complete weighting astrometric observations of Triton, a possible minimum value of the Neptunian tidal dissipation factor <i>Q</i> was estimated to be <i>Q</i> = (10.353 ± 2.517) × 10³ for a conventional value <i>k</i>₂ = 0.127 and a priori constraint of 10 × 10³. When the a priori constraints have a smaller value, the <i>Q</i>-solution also has a smaller value but a weak fit to observations. Therefore, the <i>Q</i> estimated from the existing astrometric data is a plausible minimum value with the current accuracy of astronomical observations. Based on the plausible minimum value of <i>Q</i> and the Love number <i>k</i>₂, it has been analyzed that Triton will reach Neptune’s Roche limit in approximately ~28 Gyr.

The IMP self-propelled chassis is equipped with various attachments that determine the purpose and technological characteristics of the vehicle. Such vehicles can be used both as independent lunar rovers with hybrid control and as links in a multifunctional lunar train designed for special operations, including long-distance expeditions of hundreds of kilometers. Based on the NASA-published Lunar Reconnaissance Orbiter Camera images, a possible expedition route has been mapped from the International Lunar Research Station (ILRS) location in the Malapert massif region to the far side of the Moon, taking into account illumination levels and terrain elevation angles along the entire route. The expedition’s objective is to conduct scientific research along the route, deliver equipment, and deploy an automated ILRS branch—a lunar observatory on the far side of the Moon in the radio-quiet shadow from Earth.

Some problems of planet accumulation and migration of planetesimals, small bodies and dust in the forming and present Solar System are considered. It has been noted that the outer layers of the Earth and Venus could have accumulated similar planetesimals from different areas of the feeding zone of the terrestrial planets. In addition to the theory of coaccretion and the mega-impact and multi-impact models, the formation of the embryos of the Earth and the Moon from a common rarefied condensation with subsequent growth of the main mass of the embryo of the Moon near the Earth is also discussed. Along with the Nice model and the “grand tack” model, a model is considered in which the embryos of Uranus and Neptune increased the semimajor axes of their orbits from values of no more than 10 AU to present values only due to gravitational interactions with planetesimals (without the motions of Jupiter and Saturn entering into resonance). The influence of changes in the semimajor axis of Jupiter’s orbit on the formation of the asteroid belt is discussed, as well as the influence of planetesimals from the feeding zone of the giant planets on the formation of bodies beyond the orbit of Neptune. The migration of bodies to the terrestrial planets from different distances from the Sun is considered. It is noted that bodies from the feeding zone of the giant planets and from the outer asteroid belt could deliver to the Earth a quantity of water comparable to the mass of water in the Earth’s oceans. The migration of bodies ejected from the Earth is considered. It is noted that about 20% of the ejected bodies that left the Earth’s sphere of influence eventually fell back to the Earth. The probabilities of collisions of dust particles with the Earth are usually an order of magnitude greater than the probabilities of collisions of their parent bodies with the Earth. The migration of planetesimals is considered in exoplanetary systems Proxima Centauri and TRAPPIST-1. The amount of water delivered to the inner planet Proxima Centauri b, may have been more than the amount delivered to the Earth. The outer layers of neighboring planets in the TRAPPIST-1 system may contain similar material if there were many planetesimals near their orbits during the late stages of planetary accumulation.</p>","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"58 1 supplement","pages":"S50 - S63"},"PeriodicalIF":0.6,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679692","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}
