Sulfur Cycling as a Viable Metabolism under Simulated Noachian/Hesperian Chemistries

Life, 2022
Water present on the surface of early Mars (>3.0 Ga) may have been habitable. Characterising analogue environments and investigating the aspects of their microbiome best suited for growth under simulated martian chemical conditions is key to ...

The ISSI international study team on the martian PBL – status report and plan [PDF]

, 2008
Dynamical processes in the Martian boundary layer provide the means of communication between surface ice deposits and the free atmosphere, and the means of lifting dust from the surface.

Jarosite stability on Mars [PDF]

, 2005
Jarosite, a potassium (sodium) iron sulphate hydrated mineral, has recently been identified on the martian surface by the Opportunity rover. Using recent thermochemical data [Drouet and Navrotsky, 2003, Geochim. Cosmochim.

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

Journal of Raman Spectroscopy, EarlyView.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

The Martian Boulder Automatic Recognition System, MBARS

Earth and Space Science, 2022
Boulder‐sized clasts are common on the surface of Mars, and many are sufficiently large to be resolved by the high resolution imaging science experiment (HiRISE) camera aboard the Mars reconnaissance orbiter. The size, number, and location of boulders on

Photovoltaics-Driven Power Production Can Support Human Exploration on Mars

Frontiers in Astronomy and Space Sciences, 2022
A central question surrounding possible human exploration of Mars is whether crewed missions can be supported by available technologies using in situ resources.

The depth of the convective boundary layer and implications for a Walker-like circulation on Mars [PDF]

, 2011
Radio science observations indicate that the depth of the martian convective boundary layer varies strongly with surface height, although the surface temperature does not.

Characterization of the Martian Surface Layer [PDF]

Journal of the Atmospheric Sciences, 2009
Abstract The authors have estimated the diurnal evolution of Monin–Obukhov length, friction velocity, temperature scale, surface heat flux, eddy-transfer coefficients for momentum and heat, and turbulent viscous dissipation rate on the Martian surface layer for a complete sol belonging to the Pathfinder mission. All these magnitudes have
