The origin of alteration “orangettes” in Dhofar 019: Implications for the age and aqueous history of the shergottites [PDF]

, 2017
The shergottites are the largest group of Martian meteorites, and the only group that has not been found to contain definitive evidence of Martian aqueous alteration.

Radar Observations of Liquid Water in the South Polar Region of Mars: Indications from Astrobiology Perspectives

Universe
In recent decades, extensive research has led to the understanding that Mars once hosted substantial liquid-water reserves. While the current Martian landscape boasts significant water-ice deposits at its North and South poles, the elusive presence of ...

Kinetic model of carbonate dissolution in Martian meteorite ALH84001 [PDF]

, 2003
The magnetites and sulfides located in the rims of carbonate globules in the Martian meteorite ALH84001 have been claimed as evidence of past life on Mars.

Simulating evaporative wet and dry cycles in Gale crater, Mars using thermochemical modeling techniques

Meteoritics &Planetary Science, EarlyView.
Abstract The aim of this work is to provide a model‐backed hypothesis for the formation of evaporites—sulfates, borates—in Gale crater using thermochemical modeling to determine constraints on their formation. We test the hypothesis that primary evaporites required multiple wet–dry cycles to form, akin to how evaporite assemblages form on Earth ...

Simultaneous Two‐Point Study of the Martian Bow Shock Affected by an Interplanetary Coronal Mass Ejection: Tianwen‐1 and MAVEN Observations

Geophysical Research Letters
The Martian bow shock (BS) plays a significant role in the Martian plasma environment. Based on observations from Tianwen‐1 and MAVEN, we first report two cases of simultaneous two‐point crossings of the Martian BS affected by an interplanetary coronal ...

Temporal and Spatial Prediction of Column Dust Optical Depth Trend on Mars Based on Deep Learning

Remote Sensing
Dust storms, as an important extreme weather event on Mars, have significant impacts on the Martian atmosphere and climate and the activities of Martian probes. Therefore, it is necessary to analyze and predict the activity trends of Martian dust storms.

Pairing relationships of howardites, eucrites and diogenites (HED) from the Miller Range ice fields, Antarctica

Meteoritics &Planetary Science, EarlyView.
Abstract We reevaluated pairing relationships among 56 Antarctic howardites, eucrites, and diogenites (HED) from the Miller Range ice fields (MIL) based on new measurements of cosmogenic radionuclides and bulk composition of 28 HED samples and one HED‐related dunite.

Improved general circulation models of the Martian atmosphere from the surface to above 80 km

, 1999
We describe a set of two “new generation” general circulation models of the Martian atmosphere derived from the models we originally developed in the early 1990s.
