Compressional stresses from the basalt basins on the lunar are responsible for the formation of wrinkle ridges in lunar mare basalts. According to the wide angle multispectral camera (WAC) mosaic image, we selected 62, 75, 73, and 58 single wrinkle ridges in Mare Imbrium, Mare Serenitatis, Mare Fecunditatis, and Mare Tranquillitatis, respectively,...

Research on the lithospheric elastic thickness (Te) of lunar mascon basins can provide a deeper understanding of heterogeneous thermal activity. In this study, we focused on four basins (Moscoviense, Freundlich‐Sharonov, Hertzsprung, and Apollo) located on the far side of the Moon. These basins exhibit a significant variation in admittance and corr...

Incomplete studies exist on the identification and formation processes of lunar cryptomaria, which stand as crucial hubs of late lunar magma ocean activity and early volcanism, presenting a mystery in their orgin. Here, we show 29 delineated cryptomaria regions, based on remote sensing data. A thorough investigation of gravity anomalies within thes...

Maps of lunar wrinkle ridges (LWRs) were created from 70°N to 70°S and 140°E to 140°W (extracted and highlighted the major LWRs area) using automated LWRs detection process with Lunar Reconnaissance Orbiter Camera wide range angle camera and Lunar Orbiter Laser Altimeter data. Automatic detection of LWRs is challenging because the ridges are of irr...

Mons Gruithuisen is a rare example of nonmare silicic volcanoes on the Moon. We have conducted analyses of the topography, chemical compositions, and subsurface structures of the Gruithuisen region based on remote sensing and gravity data. Our findings include presence of newly detected magma chambers in addition to the previously identified silici...

Characterizing the thermophysical properties of the lithosphere is critical for studying its evolution. We determine the elastic thickness of the lithosphere by modeling mass‐related loads and lithospheric deflection and analyzing gravity and topography data. In impact basins region where a mantle plug is present, the correlation between topography...

The elastic thickness of a planet's lithosphere is essential to the investigation of its thermal evolution. Our work focuses on the largest visible impact basin on Mercury, Caloris, which has undergone complex magma‐tectonic deformation after its formation. Using a flexural lithosphere model with the initial mantle plug loading, we estimated the el...

Lithosphere is the outer rigid part of terrestrial body, usually consisting of the crust and part of the mantle. Characterizing the physical properties of lithosphere is critical in the investigation to its evolution history. Through the modeling of mass-related loads within lithosphere, physical parameters such as elastic thickness of lithosphere...

Cryptomare, buried basalt deposits by impact ejecta, is a significant component of the lunar mare. Current research has focused on searching for cryptomaria through dark halo craters (DHCs), but there are limitations to this approach, while the cryptomaria may actually cover a much wider area. In this research, we invert the three-dimensional densi...

In this paper we investigate the relation between the spherical harmonic (SH) degree of gravity field model and the corresponding depth of the source body. By investigating the gravity of a buried point mass, we find that a relationship can be found between the horizontal extent of the signal (which we assume to be indicative of the wavelength) and...

The Moon is the primary target of human deep space exploration. The internal structure of the Moon is an essential window for us to understand the formation and evolution of the Moon and the Earth-Moon system. Compared with other geophysical fields, the gravity field model of the Moon plays an important role in the investigating of its interior str...

Context. The cryptomare in the Balmer-Kapteyn region is the oldest one on the Moon. Determining the extent and formation of this feature can deepen our understanding of early mare volcanism and help establish temporal and spatial constraints on lunar thermal and volcanic history. Aims. This paper focuses on the identification of lunar cryptomaria a...

Plain Language Summary Formation of large impact basins on Mercury, a terrestrial rocky planet, was accompanied with a rebound of the floor, which resulted in an uplift of the mantle plug beneath it. These structures are likely to subside or relax, a process influenced by the thermal structure. The crustal thickness model of Mercury reveals the geo...

The Von Kármán Crater, within the South Pole-Aitken (SPA) Basin, is the landing site of China’s Chang’E-4 mission. To complement the in situ exploration mission and provide initial subsurface interpretation, we applied a 3D density inversion using the Gravity Recovery and Interior Laboratory (GRAIL) gravity data. We constrain our inversion method u...

Gravity data provide information about the internal mass dis- tribution of celestial bodies. The latest gravity field model of Mercury, HgM007, has a higher spatial resolution than previously published gravity models, al- lowing smaller crustal structures to be resolved. In this study, a global free- air gravity anomaly grid of Mercury was derived...

The Martian gravity field has been improved significantly in terms of resolution, with the spatial resolution rising to 100 km and accuracy increasing up to the 110 degree and order, assisted by data collected in Mars exploration missions like MGS, MRO, and Odyssey. However, as the tracking data used for the Martian gravity field solution are from...
