Dark aeolian sediments in Martian craters: Composition and sources [PDF]
, 2011 Our research focuses on the mineralogical characteristics of dark sediment deposits in Martian craters (dunes, dune fields, and sand sheets) and their local sediment sources, carried out on the basis of 70 selected localities.

Perchlorates on Mars enhance the bacteriocidal effects of UV light
Scientific Reports, 2017 Perchlorates have been identified on the surface of Mars. This has prompted speculation of what their influence would be on habitability. We show that when irradiated with a simulated Martian UV flux, perchlorates become bacteriocidal.

Extraction of polar and nonpolar biomarkers from the martian soil using aqueous surfactant solutions [PDF]
, 2012 The Life Marker Chip intends to use an aqueous surfactant solution to extract both polar AND nonpolar biomarkers from the martian soil for transport to an antibody-based detection system. Currently, a solution of 1.5 g l-1 polysorbate 80 in 20:80 (vol:

Structure Along the Martian Dichotomy Constrained by Rayleigh and Love Waves and Their Overtones
Geophysical Research Letters, 2023 Using seismic recordings of event S1222a, we measure dispersion curves of Rayleigh and Love waves, including their first overtones, and invert these for shear velocity (VS) and radial anisotropic structure of the Martian crust.

Optical Constants of Martian Dust Analogs at UV–Visible–Near-infrared Wavelengths
The Astrophysical Journal Supplement Series, 2023 We present an advanced light-scattering model to retrieve the optical constants of three Martian dust analogs: Johnson Space Center regolith simulant, Enhanced Mojave Mars Simulant, and Mars Global Simulant.

Experimental Investigation of the Atmosphere-Regolith Water Cycle on Present-Day Mars
Sensors, 2021 The water content of the upper layers of the surface of Mars is not yet quantified. Laboratory simulations are the only feasible way to investigate this in a controlled way on Earth, and then compare it with remote and in situ observations of spacecrafts

Solar radiation incident on the Martian surface [PDF]
Journal of Molecular Evolution, 1979 Calculations indicate that the maximum daily solar radiation reaching the Martian surface is about 325 cal/cm2 during southern hemisphere summer at latitude of about 40 degrees S. In the ultraviolet region of the spectrum, the radiation reaching the surface at wavelengths greater than 2800 A is within 10% of the radiation incident on the atmosphere ...

Mineralogical characterization of Martian Jezero crater from MRO CRISM hyperspectral images [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 Martian mineral detection and mapping can provide important information and constraints on Martian aqueous history, which can be used to assess the potential habitability of Mars.
