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

Exploring Enceladus's Interior Structure Using Electromagnetic Induction

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Electromagnetic (EM) sounding can constrain the electrical structure of Enceladus and, in turn, the salinity of its ocean and the porosity, fluid content, and thermal state of its hydrothermally active core. Here, we assess the feasibility of EM sounding at Enceladus using both global (orbiter) and local (lander) EM induction transfer ...

Mercury’s Low‐Latitude Boundary Layer: Identification of Distinct Proton Populations Using MESSENGER Spacecraft Data

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract We have performed a comprehensive analysis of Mercury’s Low‐Latitude Boundary Layer (LLBL) using data from the MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) spacecraft during its orbital phase. Using combined magnetic field and ion measurements, we identified 202 LLBL events and categorized them into three distinct ...

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 ...
