The OMEGA/Mars Express Dust Storm Catalog

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract This paper describes the OMEGA Dust Storm Catalogue (ODSC), built over almost 4 Martian Years (end of MY 26 to mid MY 30d) from OMEGA/Mars Express hyperspectral observations. A storm detection method has been developed based on a pixel clustering algorithm applied to the OMEGA dust optical depth retrievals made at 0.9 μ ${\upmu }$m.

In situ mineralogical-chemical analysis of Martian materials at landing/roving sites by active and passive remote sensing methods [PDF]

Remote sensing of the Martian surface from the ground and from orbiting spacecraft has provided some first-order insight into the mineralogical-chemical composition and the weathering state of Martian surface materials. Much more detailed information can

Saponite Bearing Material Excavated During the Formation of a Recent 25‐m‐Diameter Impact Crater in Southeastern Arabia Terra on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Mars Reconnaissance Orbiter's Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), Context Imager (CTX), and High Resolution Imaging Science Experiment observations were analyzed for a 25‐m‐wide impact crater and associated ejecta deposits located in the dust‐covered Arabia Terra region.

Petrologic constraints on the pressure, temperature, time and composition of the Martian interior [PDF]

Petrologic analysis of surface samples has been used to deduce pressure and temperature conditions existing in the crust and upper mantle at specific times in the Earth's history, as well as to estimate the chemical and mineralogical composition of the ...

How Do Martian Dust Devils Vary Throughout the Sol? [PDF]

, 2016
Dust devils are vortices of air made visible by entrained dust particles. Dust devils have been observed on Earth and captured in many Mars lander and orbiter images. Martian dust devils may be important to the global climate and are parameterised within

An Aeolian Depositional Sequence Shaped by Near‐Surface Water at the Base of the Layered Sulfate Unit, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The basal strata of the orbitally defined Layered Sulfate unit (LSu) in Gale crater, Mars, marks the end of a major mineralogical transition from clay‐to sulfate‐bearing stratigraphy. This has previously been attributed to a period of significant aridification of Gale's climate. Here, we present ground‐based observations by the Curiosity rover

Ozone Detector Based on Ultraviolet Observations on the Martian Surface

Remote Sensing
Ozone plays a key role in both atmospheric chemistry and UV absorption in planetary atmospheres. On Mars, upper-tropospheric ozone has been widely characterized by space-based instruments.

Soil development and sampling strategies for the returned Martian surface samples [PDF]

Sampling of the Martian surface materials should be based on the experience gained from the study of soils and rocks collected in cold, dry environments, i.e., dry valleys of Antarctica.

Hydromagnesite Precipitation in an Ultramafic‐Hosted Alkaline Lake: Insights From Lake Salda for Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Lake Salda (SW Turkey) is one of the most compelling terrestrial analogs for Jezero Crater on Mars due to its highly alkaline, Mg‐rich waters and hydromagnesite‐forming microbialites. This study integrates hydrochemical measurements, saturation‐index modeling, SEM–TEM imaging, and X‐ray diffraction (XRD) analysis to disentangle the biotic and ...

Photovoltaic array for Martian surface power [PDF]

Missions to Mars will require electric power. A leading candidate for providing power is solar power produced by photovoltaic arrays. To design such a power system, detailed information on solar-radiation availability on the Martian surface is necessary.
