LCDNet: An Innovative Neural Network for Enhanced Lunar Crater Detection Using DEM Data
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingLunar craters are essential for spacecraft landing navigation and lunar exploration missions. Deep learning holds great promise in the crater detection task, but still faces some challenges.

Microbial Endolithic Community at Meteor Crater
Meteoritics &Planetary Science, EarlyView.Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

Anhydrous minerals in asteroid Bennu: Evidence for well‐preserved primordial components
Meteoritics &Planetary Science, EarlyView.Abstract Aqueously altered carbonaceous astromaterials are dominated by secondary minerals, but a minor fraction of primary, anhydrous silicates and oxides escape alteration, offering insight into the original composition of asteroid parent bodies. We report the mineralogy, petrology, mineral chemistry, and oxygen isotopes of anhydrous minerals—50 ...

Meteoritics &Planetary Science, EarlyView.Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

Pervasive impact modification of pristine lunar clasts
Nature CommunicationsLunar rock fragments, particularly those deemed pristine, have long been considered vital records of the Moon's formation and magmatic evolution. These fragments were thought to have largely escaped the Moon's intense impact history, offering a window into the early lunar crust. However, the concept of "pristine" is increasingly debated, as traditional

Associations Between Body Composition and Metabolic Health in Children With Obesity
Maternal &Child Nutrition, EarlyView.ABSTRACT Childhood obesity is an increasing public health problem with heterogeneous metabolic health outcomes. In children, distinguishing differences in body composition between individuals with metabolically healthy obesity (MHO) and those with metabolic syndrome (MS) may be useful for understanding the impact of body composition on metabolic health.

Global Lunar Crater Density Using Buffered Nonsparseness Correction
The Planetary Science JournalThe density of craters on a planetary surface directly relates to the age of the surface. As the surface ages, however, craters can be erased by subsequent large impacts via direct overprinting, known as geometric crater obliteration.

Pulmonary and systemic immune alterations in rats exposed to airborne lunar dust
Frontiers in ImmunologyBackgroundDue to cosmic radiation bombardment and over 4 billion meteorite and micrometeoroid impacts on the airless Moon, the lunar surface is covered by a layer of fine, reactive dust.
