The Flux of Large Impacts on the Moon Enhanced near the Beginning of the Copernican Period

The Planetary Science Journal
The size–frequency distribution (SFD) of lunar impactors was believed to be time independent for the last 3.5 billion years (Gyr). Here, I use linear and nonlinear topographic diffusion models to determine the degradation states (the integral of ...

LIBS Elemental Mapping of a Feldspathic Lunar Meteorite: Insights for In Situ Exploration

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract To meet the objectives of the many robotic and human missions planned for the Moon in the coming decade, new scientific instruments are currently under development. Laser‐induced breakdown spectroscopy (LIBS) is a robust technique for quantifying elemental abundances by focusing a pulsed laser to generate a plasma and collecting its emission ...

Lunar heat flow from the observation of Chinese Chang’E 2 and LRO diviner radiometers

AIP Advances
Lunar heat flow within 75°N to 65°S and 60°W to 100°E regions is retrieved from microwave brightness temperature observed by Chang’E-2 (CE-2) Lunar Microwave Radiometers and infrared brightness temperature observed by Lunar Reconnaissance Orbiter (LRO ...

Stratigraphy Preserved on the Jezero Crater Rim Reveals Repeated Impacts on Early Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract The outer slopes of the western Jezero crater rim are hypothesized to expose sections of Early‐ to Pre‐Noachian crust uplifted by the Jezero impact, providing an excellent opportunity to investigate the earliest geologic processes active on terrestrial planets.

Lunar Mare Lava Flow Dynamics and Emplacement: Predictions of Non-Newtonian Flow Dynamics, Syn- and Post-emplacement Cooling and Volatile Release Patterns, and Vertical and Lateral Flow Structure Development

The Planetary Science Journal
We apply basic principles of magma ascent from deep source regions and its eruption into a low-gravity vacuum environment to develop a theoretical treatment of the fluid dynamics and thermodynamics of mare basalt lava flow emplacement and evolution on ...

Geology of the central uplift of the Kamestastin Lake impact structure, Labrador, Canada

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1417-1433, July 2026.
Abstract The ~28 km Kamestastin (Mistastin) Lake impact structure is a relatively well‐preserved and well‐exposed complex impact structure. The central uplift of this structure is accessible as two islands in the middle of Kamestastin Lake. We present an updated, detailed geological map and description of Horseshoe and Bullseye islands that provides ...

The Global Distribution of Water and Hydroxyl on the Moon as Seen by the Moon Mineralogy Mapper (M3)

The Planetary Science Journal
The Moon Mineralogy Mapper (M ^3 ) on the Chandrayaan-1 spacecraft provided nearly global 0.5–3 μ m imaging-spectroscopy data at 140 m pixel ^–1 in 85 spectral bands. Targeted locations were imaged at 70 m pixel ^–1 and higher spectral resolution.

Morphometric Analysis of the Jingpo Lake Volcanic Field: A Terrestrial Analog for Lunar Lava Flow

Remote Sensing
The lack of high-precision imaging data for lunar volcanic regions currently hinders the detailed characterization of lava tube systems and their associated fine-scale geomorphology.

Refining Constraints on the Origin of Lunar Irregular Mare Patches via Mini-RF and DFSAR Data Analysis

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Irregular mare patch (IMP) is one of the most enigmatic volcanic features in the lunar nearside maria. Their apparently fresh surface morphology and derived young model ages contradict the currently proposed thermal evolution history of the Moon.
