Two‐Stage Framework for Precise Measurement of Marsquake Surface Wave Group Velocity Dispersion

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Surface wave dispersion analysis is crucial for investigating crustal and mantle structures on Earth and other celestial bodies. On Mars, Rayleigh and Love waves have been detected, with Rayleigh waves exhibiting vertical and radial motion and Love waves polarized transversely to the source‐receiver azimuth.

Physiological and technological considerations for Mars mission extravehicular activity [PDF]

The nature of the suit is a function of the needs of human physiology, the ambient environment outside the suit, and the type of activity to be accomplished while in the suit.

A Simple Subgrid‐Scale Model for Slope Winds on Mars

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Global Climate Models (GCMs) are useful tools for simulating the dynamics of Mars atmosphere on a planetary scale. However their coarse resolution (∼ ${\sim} $100 km) does not allow to capture small‐scale phenomena such as slope winds which can occur over scales of just a few kilometers.

Seasonally Dependent Formation of Sulfates in the Basque Lakes, British Columbia, as Analogous to “Cold and Wet” and “Warm and Wet” Mars

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Saline lakes are expected to have been extensively present on ancient Mars, particularly as the planet dried or cooled. Such lakes likely deposited sulfate salts, as these salts have been widely identified from orbital and in situ Mars data. However, the relationship between martian sulfates and the environmental conditions that formed them ...

Carbon reservoirs on Mars: Constraints from Martian meteorites [PDF]

, 2003
We have measured the abundance and stable isotopic composition of magmatic carbon extracted from a suite of shergottites. The results confirm previous findings that primordial carbon on Mars is isotopically lighter than that of the ...

Methods for Cleaning Apollo Passive Seismic Data

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Apollo passive seismic data provide a unique resource for studying the lunar interior structure. However, the raw data are frequently contaminated by various artifacts, either related to the seismic sensors and the acquisition system or to issues during data transmission to the Earth.

Predicting the probability distribution of Martian rocks mechanical property based on microscale rock mechanical experiments and accurate grain-based modeling

International Journal of Mining Science and Technology
The exploration of Mars would heavily rely on Martian rocks mechanics and engineering technology. As the mechanical property of Martian rocks is uncertain, it is of utmost importance to predict the probability distribution of Martian rocks mechanical ...

Diagenetic, Nonevaporative Origin for Calcium Sulfate Salts at Gale Crater

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Sulfate salts are deposited most commonly as evaporites on Earth; however, this is not their only origin. Pyrite oxidation during subsurface weathering is another common process on Earth that also produces a suite of sulfate salts—including the acidic phases jarosite and alunite—in sedimentary deposits.

Results of current Mars studies at the IAU Planetary Research Center [PDF]

Ground based images obtained hourly by seven observatories are used to study Martian phenomena. Maps of global dust storms show the degree of activity of the storm depends both on the region and on the time of day.
