MarsMTFormer: A Unified Multitask Transformer for Martian Surface Detection and Instance Segmentation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Martian surface understanding plays a crucial role in planetary geoscience, supporting autonomous rover navigation and geological interpretation in deep-space exploration. However, existing deep learning methods for Martian surface analysis are typically

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 Mysterious Stranger and Modern Enchantment

The British Journal of Sociology, EarlyView.
ABSTRACT Sociological accounts of modernity have long emphasized rationalization, alienation, and the attenuation of affective intensity. While these diagnoses capture crucial dynamics of modern social order, they leave underexplored a persistent and generative dimension of social life: enchantment.

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

Effects of Ambient Moisture and Large‐Strain Dynamic Preloading on the Dynamic Properties of the EAC‐1A Regolith Simulant

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5701-5711, November 2026.
ABSTRACT The EAC‐1A lunar mare simulant, a silty sand, was selected by the European Astronaut Center (EAC) for use in the LUNA analogue facility's lunar simulation testbed. Its stress‐ and strain‐dependent shear modulus and damping ratio were determined via resonant column testing on specimens prepared either from ambient moisture material or oven ...

Recent and fossil deposits of dark material in Martian Craters [PDF]

, 2006
As a result of weathering and aeolian processes a fine-grained dark material is distributed all over the Martian surface. On crater floors it is frequently accumulated as dunes. Mobile dunes are probably built and shifted by the actual wind fields.

Protein‐Independent Liquid–Liquid Phase Separation of Adenosine Triphosphate Under Crowded Conditions

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
ATP itself is able to undergo liquid–liquid phase separation in the presence of the macromolecular crowding agent PEG and physiological ATP concentrations are sufficient for phase separation in the presence of mM Mg2+ and crowders, mimicking intracellular conditions.

Evidence for silicate dissolution on Mars from the Nakhla meteorite [PDF]

, 2013
Veins containing carbonates, hydrous silicates and sulphates that occur within and between grains of augite and olivine in the Nakhla meteorite are good evidence for the former presence of liquid water in the Martian crust.

The color of the Martian sky and its influence on the illumination of the Martian surface [PDF]

Journal of Geophysical Research: Planets, 1999
The dust in the atmosphere above the Mars Pathfinder landing site produced a bright, red sky that increases in redness toward the horizon at midday. There is also evidence for an absorption band in the scattered light from the sky at 860 nm. A model of the sky brightness has been developed [Markiewicz et al., this issue] and tested against Imager for ...
