Predicted Diurnal Variation of the Deuterium to Hydrogen Ratio in Water at the Surface of Mars Caused by Mass Exchange with the Regolith [PDF]

, 2019
Regolith on Mars exchanges water with the atmosphere on a diurnal basis and this process causes significant variation in the abundance of water vapor at the surface. While previous studies of regolith-atmosphere exchange focus on the abundance, recent in-

Origin of Late Noachian‐Early Hesperian Valley Networks on Mars: Insights From Landform Evolution and Ice Sheet Modeling

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Dendritic valley networks on Mars have been cited as evidence for a warm and wet Noachian Mars, permitting rainfall precipitation and surface runoff. However, the climatic conditions required to sustain rainfall on early Mars remain debated.

Super-rotating jets in a re-analysis of the martian atmosphere [PDF]

, 2012
Strong westerly, prograde jets have been identified in the martian atmosphere between about 10–20 km altitude throughout much of the year in a Mars Global Circulation Model (MGCM) study [2]. The development of data assimilation techniques for Mars [3, 5]

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.

Compression of Martian atmosphere for production of oxygen [PDF]

The compression of CO2 from the Martian atmosphere for production of O2 via an electrochemical cell is addressed. Design specifications call for an oxygen production rate of 10 kg per day and for compression of 50 times that mass of CO2.

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.

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
