Martian Life: A Possibility-Remote Exploration of Martian Subsurface

Journal of Astrobiology & Outreach, 2015
The momentum for the search for life in the universe beyond Earth has resurged recently driven by Earth-like planets results from the Kepler space telescope as well as major financial support from wealthy individuals. There is also the question of whether there was life elsewhere in the universe.

Characteristics of Helium Bulges and the Impact of Martian Year 34 Global Dust Storm Using MAVEN/NGIMS Observations and MarsPCM and MGITM Simulations

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract We investigate spatiotemporal characteristics of helium (He) bulges using data from the Neutral Gas and Ion Mass Spectrometer aboard NASA's Mars Atmosphere and Volatile EvolutioN Mission and numerical simulations from the Mars Planetary Climate Model (MarsPCM). During equinoxes, we observed a He bulge at equatorial latitudes in addition to the

Nakhlite Emplacement as Constrained by X‐Ray Computed Tomography and 3D Quantitative Textural and Petrofabric Analyses

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Nakhlites, clinopyroxene‐rich rocks, are the largest single‐origin suite of samples from Mars. Despite extensive study to discern their petrogenetic histories, nakhlite emplacement mechanisms and environments are not well‐constrained, and it is unknown whether they represent intrusive or extrusive igneous rocks, or a combination.

Automatic Martian Polar Ice Cap Extraction Algorithm for Remote Sensing Data and Analysis of Their Spatiotemporal Variation Characteristics

Remote Sensing
The detection of Martian polar ice cap change patterns is important for understanding their effects on driving Mars’s global water cycle and for regulating atmospheric circulation.

Abrasion Patch Dehydration Experiment at Bright Angel, Jezero Crater, Using SuperCam Onboard the Mars 2020 Perseverance Rover

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Investigating the stability of hydrated minerals is integral for examining the preservation of rocks for potential Mars Sample Return and has major implications for models that use rover‐based observations to quantify Mars' global water budget.

Radiation Transport Through the Martian Atmosphere as a Function of the Zenith Angle

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract The topographic influence of the radiation environment on the Martian surface radiation is crucial for future human exploration. Topographic maps help assess radiation flux variations, aiding in hazard evaluation. Creating a global radiation map requires accounting for seasonally varying atmospheric density, heliospheric modulation, and ...

Evolution of Terrestrial Planetary Bodies and Implications for Habitability

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.
