The nature and origin of Charon's smooth plains [PDF]

, 2019
Charon displays extensive plains that cover the equatorial area and south to the terminator on the sub-Pluto hemisphere observed by New Horizons. We hypothesize that these plains are a result of Charon's global extension and early subsurface ocean ...

Automated Mineral Identification and Rock‐Type Classification of Lunar Mare Basalts Using SEM Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We present an automated system for identifying minerals and classifying rock types in Apollo lunar mare basalts using scanning electron microscopy (SEM) imagery. Mineral segmentation is based on a U‐Net architecture, supplemented by two scale‐aware models designed to incorporate pixel size information.

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.

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.

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).

Morphometric analysis of differently degraded simple craters on the moon [PDF]

, 2017
The main focus of this PhD research is the morphologic characterization of simple impact craters on lunar maria in order to find out a correlation between craters morphological degradation and absolute model ages of the surfaces where they were emplaced.

Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000

Low Abundances of Ultramafic Components in the Chang'e‐6 Landing Site Basalt and Ejecta Material

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The South Pole‐Aitken (SPA) Basin, the Moon's largest impact structure, holds key insights into lunar evolution, prompting the Chang'e‐6 mission to return first samples for ground‐truth verification. Analysis of over 6,000 grains from the Chang'e‐6 soil returned from the SPA Basin reveals a composition dominated by clinopyroxene (26.5–32.9 vol.

Regolith in Motion: Dynamic Surface Evolution After Lunar Impacts

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Multi‐temporal observations captured by the Lunar Reconnaissance Orbiter Camera provide valuable insights into contemporary surface changes. These images reveal that minor impact events (resulting in <100‐m diameter craters) significantly alter regolith structure over great distances (>1,000 crater diameters) by increasing the meter‐to ...
