The challenges in accurately capturing how gas particles interact with the objects’ surfaces result in uncertainties in their aerodynamic coefficients, directly affecting the accuracy of orbital perturbation models. Currently, gas–solid boundary interactions are accounted for by empirical models like those proposed by Sentman and Cercignani-Lampis-Lord. These models have one or two adjustable parameters, typically tuned based on orbital tracking and acceleration data. However, these models are inadequate in accurately representing crucial processes at the gas–solid interface such as multiple reflections, shadowing, and backscattering resulting from the roughness of real surfaces. We propose a new, physics-based gas-surface interaction model that leverages electromagnetic wave theory to incorporate macroscopic effects on the gas particle scattering distribution resulting from surface roughness. Besides better describing the physics of gas-surface interaction, this model’s parameters can be determined by combining ground measurements to characterise the surface roughness and molecular dynamics simulations to specify the atomic-scale interaction. The model is verified for the entire parameter range using a test-particle Monte Carlo approach on a simulated rough surface. In addition, we successfully replicate several experimental results available in literature on the scattering of Argon and Helium on smooth and rough Kapton and Aluminium surfaces. We conclude by demonstrating the model’s effect on the aerodynamic coefficients for simple shapes and comparing these results with those produced with the Sentman and Cercignani-Lampis-Lord models, thereby demonstrating that previously observed inconsistencies between these models and tracking data of spherical satellites can be explained by surface roughness.</div></div>","PeriodicalId":50850,"journal":{"name":"Advances in Space Research","volume":"76 2","pages":"Pages 811-864"},"PeriodicalIF":2.8,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144471799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Rubin crater, which formed about 1.58 billion years ago during the Eratosthenian period, excavated material from depths of up to ∼320 m, potentially reaching the underlying South Pole-Aitken (SPA) massif, Mons Amundsen. This makes the crater’s ejecta material, along with the Amundsen ejecta covering the massif, prime targets for sampling SPA-derived materials that can expand our understanding of early Solar System dynamics and the lunar cratering chronology. Additionally, the region hosts several permanently shadowed regions (PSRs), ideal for studying potential lunar volatiles and the processes affecting their distribution. The DRM proposes nine traverse options for exploration via walking EVAs, the Lunar Roving Vehicle (LRV), and LRV-assisted EVAs, with traverse lengths ranging from ∼3.6 km to ∼18.2 km. Each traverse is designed to sample diverse geologic units and address multiple scientific objectives. Given its scientific potential and favorable exploration conditions, the Rubin crater region is an ideal location for testing south polar landing operations, potentially paving the way for more complex missions, such as a Shackleton crater landing.</div></div>","PeriodicalId":50850,"journal":{"name":"Advances in Space Research","volume":"76 2","pages":"Pages 796-810"},"PeriodicalIF":2.8,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144471798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eight environmental factors were identified via correlation analysis: elevation, slope, aspect, stratigraphic lithology, and distances from faults, roads, rivers, and areas of land use. Subsequently, we constructed an information value model. For training the IV-RF model, non-landslide points in areas of low susceptibility were randomly selected at various ratios (1:1, 1:2, 1:3, 1:4, 1:5). The optimal ratio was used to develop coupled models (IV-RF, IV-LR, IV-SVM, IV-BP), comparing their accuracy and discussing the impact of environmental factors on landslide susceptibility. Results indicate that: (1) the highest prediction accuracy was achieved with a non-landslide ratio of 1:1; (2) the IV-RF model achieved the highest AUC of 0.994; and (3) the most significant factors influencing landslide distribution were stratigraphic lithology and river proximity, followed by elevation and fault distance.</div></div>","PeriodicalId":50850,"journal":{"name":"Advances in Space Research","volume":"76 2","pages":"Pages 699-717"},"PeriodicalIF":2.8,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144471588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These new records provide an independent confirmation of the sunspot groups observed in 1671, complementing previous works based on observations by other astronomers. Moreover, they highlight some corrections for future versions of the group number database. On the other hand, by compiling all sunspot data for 1671 published so far, we improve our knowledge of the solar activity level in that year. We obtained that the percentage of active days (days when sunspots were observed on the solar disc) was 21.3 %, although with a high uncertainty ranging between 6.3 % and 76.7 % considering days without any record as spotless or active days, respectively. Despite being one of the more active years in the Maunder Minimum, we conclude that the solar activity level in 1671 remains low in comparison to other periods of reduced solar activity, such as the Dalton Minimum.
