Absolute ages from crater statistics: Using radiometric ages of Martian samples for determining the Martian cratering chronology [PDF]
In the absence of dates derived from rock samples, impact crater frequencies are commonly used to date Martian surface units. All models for absolute dating rely on the lunar cratering chronology and on the validity of its extrapolation to Martian ...

Mars Orbiter Laser Altimeter: Experiment summary after the first year of global mapping of Mars [PDF]
, 2001 The Mars Orbiter Laser Altimeter (MOLA), an instrument on the Mars Global Surveyor spacecraft, has measured the topography, surface roughness, and 1.064-μm reflectivity of Mars and the heights of volatile and dust clouds.

Explainable Machine Learning for Mapping Minerals From CRISM Hyperspectral Data
Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.Abstract This paper addresses some of the challenges in automating mineral mapping from CRISM hyperspectral data using two ML algorithms, namely, Random Forest (RF) and Gradient Boosted Trees (GBTree) algorithms. An interpretable framework using tree‐ensemble classification and SHapely Additive exPlanations (SHAP) is implemented to interpret the model ...

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.Abstract The Emirates Mars Ultraviolet Spectrometer (EMUS) aboard the Emirates Mars Mission (EMM) has been studying backscattered interplanetary hydrogen (interplanetary hydrogen (IPH)) Lyman emissions with dedicated observation strategies viz., U‐OS3b and U‐OS4b. These observation techniques involve looking away from Mars from the EMM's orbit.

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.Abstract Maars are volcanoes with a central crater surrounded by an ejecta ring formed through surface explosive processes from underlying magma interacting with fluids. The study of terrestrial maar volcanoes, as analogs to explosive volcanic vents on the Moon and other planets, can improve our understanding of planetary volcanism and evolution.

The Planetary Science JournalThe Martian atmospheric Ne may reflect recent gas supply from its mantle via volcanic degassing, due to its short (∼100 Myr) escape timescale. The isotopic ratio of the Martian atmospheric Ne would therefore provide insights into that of the Martian ...
