Microbial growth in actual martian regolith in the form of Mars meteorite EETA79001
Communications Earth & Environment, 2023 Studies to understand the growth of organisms on Mars are hampered by the use of simulants to duplicate martian mineralogy and chemistry. Even though such materials are improving, no terrestrial simulant can replace a real martian sample.

A GRADIENT-REGION CONSTRAINED LEVEL SET METHOD FOR AUTONOMOUS ROCK DETECTION FROM MARS ROVER IMAGE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 Rocks are one of the major Martian surface features and yield significant information about the relevant geology process and the life exploration. However, autonomous Martian rock detection is still a challenging task due to the appearance similar to the

A Thermal Plume Model for the Martian Convective Boundary Layer
, 2013 The Martian Planetary Boundary Layer [PBL] is a crucial component of the Martian climate system. Global Climate Models [GCMs] and Mesoscale Models [MMs] lack the resolution to predict PBL mixing which is therefore parameterized.

ESTIMATION OF AEOLIAN DUNE MIGRATION OVER MARTIAN SURFACE EMPLOYING HIGH PRECISION PHOTOGRAMMETRIC MEASUREMENTS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 At the present time, arguments continue regarding the migration speeds of Martian dune fields and their correlation with atmospheric circulation. However, precisely measuring the spatial translation of Martian dunes has been rarely successful due to the ...

Impact of surface Albedo on Martian photochemistry [PDF]
Earth and Planetary Physics, 2020 Solar energy is the primary driving force behind a planet’s climate system, and surface albedo plays a key role in determining the energy budget of the planet. Coupling the Snow, Ice, and Aerosol Radiation (SNICAR) with the Laboratoire de Météorologie Dynamique (LMD) Mars General Circulation Model (MGCM) to create a new coupled model leads to an ...
