The most attractive missions for implementation are those with minimal propellant consumption, allowing for an increase in payload mass and a wider range of operations on the surface of the celestial body. We propose a method for selecting near-Earth asteroids and initial ballistic designing the trajectories to transfer small bodies to heliocentric orbits resonant with the Earth’s orbit at minimal changes in the characteristic velocity (delta-v budget) and moderate mission duration. The catalog of targets is formed according to geometric and dynamic criteria, after which the delta-v budget maps are constructed, separating the contributions of the upper stage and the spacecraft. Next, the phasing impulse of the spacecraft on the asteroid’s surface, ensuring that the asteroid is transferred to an orbit with a period equal to one Earth year, is modeled. This choice of a period guarantees annual returns to the vicinity of the Earth and creates conditions for a sequence of combined gravity-assist maneuvers in the Earth–Moon system, which makes it possible to reduce the velocity of the asteroid in the geocentric system while its heliocentric velocity remains almost unchanged. The subsequent dynamics of resonant approaches are analyzed to find favorable windows for prospective gravity-assist maneuvers and a possible capture of the asteroid into the orbit around the Earth. The feasibility of the proposed mission profile is demonstrated by the examples of several objects.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737767","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}

It was shown (Evdokimov and Shematovich, 2025a, 2005b) that the magnitude of the loss of the hydrogen–helium envelope due to the heat flux from the core strongly depends on the structure of the interior of the mini-Neptune HD 207496b. The presence of a water mantle, which makes up a significant portion of the planet’s mass, increases the core radius and its heat capacity, leading to increased atmospheric losses. In this study, we conducted a more detailed analysis of this effect by simulating the escape of the primary gas envelope for mini-Neptunes with varying water mass fractions, given their mass, initial atmospheric mass fraction, and equilibrium temperature. The calculations were performed both for model planets with specified parameters and for HD 207496b, taking into account previously unstudied factors such as the radiogenic heat source and the evolution of the host star. The strong dependence of the loss of the primary atmosphere on the water content in the planet interiors of mini-Neptunes was confirmed. The significant influence of the early evolutionary stages of the host stars on the history of their primary gas envelopes was demonstrated. It has been shown that the heat flow due to the presence of radionuclides (including aluminum-26) in the silicate mantle of mini-Neptunes has almost no effect on the process of loss of the primary gas envelope, provided that the content of radionuclides corresponds to the content of chondrite matter in the early Solar System.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S0038094626600095.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These altitudes include a transition zone called the turbopause, where the diffusion regime of atmospheric parcels changes from turbulent to molecular. Variations of the turbopause altitude and temperature are influenced by seasonal variability and vertical energy transfer due to global circulation and atmospheric gravity waves. Our research is based on the analysis of temperature and CO2 density vertical profiles measured during solar occultations by the Atmospheric Chemistry Suite (ACS) on board the Trace Gas Orbiter (TGO) of the ExoMars-2016 mission. The statistics of the analyzed profiles cover seasons spanning 3.5 Martian years (MY), from the middle of MY 34 (May 2018) to the end of MY 37 (November 2024), with atmospheric altitudes ranging from 10 to 170 km. Based on the processed vertical wave profiles, the coefficients of molecular and turbulent diffusion were estimated assuming saturated gravity waves. The derived turbopause height varies from 90 km at aphelion to 135 km at perihelion with its CO2 density ranging from 1010 to 1012 cm–3 and diffusion coefficients ranging between 106 and 5 × 107 cm2/s. The estimated average wave-induced phase wind speed is 43 m/s while the mean-square thermal speed is 270 m/s at the turbopause layer. The obtained results could be utilized to refine circulation models in calculations of vertical parcel transport in the upper atmosphere.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S0038094626600186.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that when predicting the motion of the asteroids being studied, it is necessary to take into account the gravitational influence of the planets, the Moon, Ceres, Pallas and Vesta, the relativistic effects of the Sun and the oblateness of the Sun. Radiation pressure has a significant effect on the motion of approximately half of the asteroids with known physical parameters. Evaluation of the influence of the Yarkovsky effect on the motion of objects with a known parameter A2 showed that this disturbance is significant and requires consideration when studying the motion of these asteroids. For 1404 objects we obtained numerical estimates of the parameter A2, performed using an automatic procedure implemented in the IDA software package. The estimates obtained can be divided into two groups: 71% of asteroids have an observation arc of less than 300 days, for them the estimate of A2 most often is overstated. The objects of the second group are characterized by a well-defined orbit, the values of the parameter A2 obtained for them correspond to analytical estimates.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147561003","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}

Understanding how these compounds are destroyed at different temperatures is important for revealing the geological and climatic evolution of the planets and other bodies in the Solar System, as well as assessing their habitability. Here, we present the results of experiments on the radiolysis of sodium perchlorate NaClO4 at temperatures of 133 and 208 K. As the temperature increases, our results show that the amount of perchlorate destroyed and the radiolysis effectiveness increase. We detected the formation of secondary chlorine-containing products (NaClO3, NaClO2, and NaCl). NaClO3 was the predominant product, while NaClO2 and NaCl were only detected at the higher temperature of 208 K. The yields of NaClO3 and NaCl increased with absorbed dose, whereas NaClO2 decreased, indicating a dose-dependent formation of oxychlorine species in varying oxidation states during perchlorate decomposition. These findings provide insights into the pathways of perchlorate radiolysis and the temperature- and dose-dependent formation of secondary products relevant to planetary surfaces.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147336845","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}

We have shown that all the nongravitational acceleration models considered, when determined simultaneously with the coordinates and velocities at the chosen epoch, yield almost the same level of agreement with observations—the only exception being the constant-acceleration model (1/r0). Notably, the derived values of nongravitational accelerations exceed those characteristics of both Solar System comets and the first known interstellar comet, 2I/Borisov. In every model considered, the relationship |A1|/|A2| < 1 holds, meaning that the total nongravitational acceleration deviates markedly from the sunward direction, since the radial and transverse components are mutually perpendicular. This can be attributed either to rapid rotation of the nucleus or to pronounced inhomogeneity of its surface. For the dependencies proportional to 1/r0, 1/r3, and 1/r4, as well as in the Marsden model, the value of the parameter A1 proves to be negative. An analysis of the O–C values (differences between the observed and calculated positions) revealed no statistically significant periodic variations. Using the inject-and-recover test, we estimated the upper limit on the amplitude of hypothetical periodic O–C variations, at which their period could be reliably recovered from the available observational data.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147336383","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}

Numerical calculations revealed characteristic absorption lines of pure minerals (end members of solid melts), which made it possible, in comparison with the spectra of natural samples, to determine the influence of chemical composition and impurities. IR transmission spectra of experimental mixtures of anorthite and olivine with different proportions made it possible to identify the most characteristic signs of the presence of olivines in Ca-plagioclase powder.
