Samples from Martian craters: Origin of the Martian soil by hydrothermal alteration of impact melt deposits and atmospheric interactions with ejecta during crater formation [PDF]

open access: yes
The origin of the Martian soil is an important question for understanding weathering processes on the Martian surface, and also for understanding the global geochemistry of Mars.

Perspective View of Hydrology on the Martian Surface

open access: yesMalaysian Journal of Science and Advanced Technology
The discovery of water ice within craters at the Martian North Pole has provided unprecedented insights into the planet's hydrology and climatic history. High-resolution images from the Mars Reconnaissance Orbiter (MRO) have revealed extensive ice deposits in these craters, some spanning several kilometers, offering a detailed perspective of Mars ...

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

open access: yes
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.

Snow and regolith albedo variations using CRISM data at McMurdo crater, Mars

open access: yesEarth and Planetary Physics
The cryosphere component provides the most reliable and insightful indications of any planet’s climate dynamics. Using data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), we develop a novel approach to determining the broadband ...

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

open access: yes
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

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

open access: yes, 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

Electron Spin Resonance (ESR) detection of active oxygen species and organic phases in Martian soils [PDF]

open access: yes
The presence of active oxygen species (O(-), O2(-), O3(-)) and other strong oxidants (Fe2O3 and Fe3O4) was invoked in interpretations of the Viking biological experiments and a model was also suggested for Martian surface chemistry.
