Topographical Features of the Lunar Surface Unveiled Through Spherical Geodesic Triangulation Analysis Method of DEM Roughness at Equal Spatial Scales

Earth and Space Science
This study introduces an innovative method using equal spherical geodesic triangulation to uniformly sample the digital elevation model (DEM) of the lunar surface, ensuring an even distribution of elevation data.

Impact provenance and age of a unique basalt found in Apollo 12 regolith

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2073-2085, August 2026.
Abstract Basaltic sample 12032,366‐18 from the Apollo 12 landing site is distinct among basalts collected at this site, other Apollo landing sites, and lunar meteorites in terms of its age, bulk rock composition, and isotopic composition. We present new Pb isotopic data obtained by in situ Secondary Ion Mass Spectrometry on multiple mineral phases in ...

Surface Roughness of the Chang’E-6 Lunar Samples and Landing Site from Submicrometer to Kilometer Scales: Implications for Lunar Surface Processes and Remote Sensing Data Modeling

The Astronomical Journal
Although lunar surface roughness was studied extensively above micrometer scales before, it has not been investigated at smaller scales. In this study, we used an atomic force microscope to measure surface elevations of the Chang’E-6 lunar samples at ...

AUTOMATED DETECTION OF LUNAR RIDGES BASED ON DEM DATA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Wrinkle ridges are a common feature in the lunar maria and record subsequent contraction of mare infill. Automatic detection of wrinkle ridges is challenging because the ridges are of irregular shapes and many ridges have been eroded and/or degraded over

Distribution of Buried Volcanic Deposits in the Schiller–Schickard Region of the Moon

The Planetary Science Journal
Cryptomaria are ancient volcanic units on the Moon that are key to understanding early lunar thermal history but are difficult to study because they have been buried and obscured from direct view by later impact ejecta.

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK Pathways

Arthritis &Rheumatology, Volume 78, Issue 7, Page 1535-1553, July 2026.
Objective Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

The Production Population of Impact Craters in the Chang’E-6 Landing Mare

The Astrophysical Journal Letters
The Chang’E-6 mission accomplished the first sample return from the lunar farside. Earlier crater population measurements estimated the model age of the landing mare to range from the Eratosthenian to Late Imbrian, both of which are underrepresented by ...

Geology and Chronology of the Lunar Taruntius Crater: Implications for the Retention Age of Lunar Ray Patterns and Lifetime of Lunar Explosive Volcanism

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Taruntius crater, situated between Maria Fecunditatis, Crisium, and Tranquillitatis, is characterized by a prominent bright ray system and a floor‐fractured morphology and has long been interpreted as a relatively young Eratosthenian or Copernican crater.

Surface Roughness of the Chang’E-5 and Chang’E-6 Lunar Samples: Implications for the Microscopic Processes Shaping the Lunar Surface

The Planetary Science Journal
 Although lunar surface roughness was studied extensively above micrometers before, it has not been investigated at smaller scales. In this study, we measured the surface topography of the Chang’E-5 and Chang’E-6 lunar samples by using atomic force ...

Occurrence and Provenance of KREEP Components in Glassy Agglutinates From Chang'e‐5 Lunar Regolith

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract This study investigates the petrogenesis of glassy agglutinates in a polished section of the Chang'e‐5 lunar regolith sample CE5C0800YJYX018GP through integrated petrographic, mineralogical, and geochemical analyses of four representative particles (18GP‐01 to 18GP‐04).
