Obscuration of Crystalline Ca‐Sulfate in XRD and Raman Data When Coated by Amorphous Ferric Sulfate: Implications for the Amorphous Components at Gale Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Throughout Gale crater on Mars, the Curiosity rover has found high abundances (15–73 wt%) of X‐ray amorphous materials in the rocks and sediments. The composition of this amorphous fraction is primarily calculated by subtracting crystalline abundances measured by the Chemistry & Mineralogy X‐Ray Diffractometer (CheMin) from bulk elemental ...

Rapid Response of Martian Magnetotail to Solar Wind Disturbance: Tianwen‐1 and MAVEN Joint Observations

Geophysical Research Letters
The Martian magnetotail is largely controlled by the solar wind (SW) and is modulated by variations in the upstream drivers. However, due to the limitations of single‐spacecraft observations, the effects of SW variations on the Martian magnetotail have ...

A Study on CO2 ${\text{CO}}_{2}$ Supersaturation in the Martian Southern Polar Night Using Mars Global Surveyor Radio Occultation Profiles Rederived With Mars Climate Sounder Temperature Climatology

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We investigate CO2 ${\text{CO}}_{2}$ supersaturation in the Martian southern polar night using rederived vertical profiles from Mars Global Surveyor (MGS) radio occultation (RO) measurements. Supersaturation, which affects not only local condensation but also the polar and global atmospheric dynamics, occurs when temperatures fall below the ...

Soil microstructure and electron microscopy [PDF]

As part of the process of comparing Martian soils with terrestial soils, high resolution electron microscopy and associated techniques should be used to examine the finer soil particles, and various techniques of electron and optical microscopy should be

On the Possibility of Melting Water Ice During the Recent Past of Mars: Implications for the Formation of Gullies

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The formation of gullies on Mars has often been attributed to the melting of (sub)surface water ice. However, melting‐based hypotheses generally overlook key processes: (a) sublimation cooling by latent heat absorption, (b) the non‐stability of ice where melting conditions can be reached, and (c) the particular microclimates of gullied slopes.

MAVEN EUVM Data Products for Space Weather at Mars

Space Weather, Volume 24, Issue 2, February 2026.
Abstract Space weather monitoring is critical to protect not only our technological assets in space, but also mitigate disruptions to life and society that depends on these vulnerable assets. Significant attention and resources have been dedicated to space weather monitoring at Earth, but little attention to date has been paid to planetary space ...
