A Global High-Resolution Hydrological Model to Simulate the Dynamics of Surface Liquid Reservoirs: Application on Mars
Surface runoff shapes planetary landscapes, but global hydrological models often lack the resolution and flexibility to simulate dynamic surface water bodies beyond Earth. Recent studies of Mars have revealed abundant […]

Modelling The Long-term Impacts Of Artificial Warming On The Martian Water Cycle And Surface Ice Distribution
Recent papers by Ansari et al. (2024, Science Advances 10, eadn4650) and Richardson et al. (2025, arXiv eprint 2504.01455) have suggested that global warming of the Martian surface (‘terraforming’) by […]

The Martian Mid-latitude Subsurface Ice Is The Remnant Of A Past Ice Sheet
On Mars, a relatively pure water ice layer lies beneath several centimeters of dry soil at mid-latitudes. Its widespread presence poleward of 60° latitude was detected by remote neutron spectroscopy […]

Active High-Latitude Dune-Gullies On Mars
Gully and defrosting activity have been visible here along the edge of a dune field, along with blocks of frost. Observations of the same area help us check for repeat […]

Sculpting Of Martian Brain Terrain Reveals The Drying Of Ancient Mars
The Martian brain terrain (MBT), characterized by its unique brain-like morphology, is a potential geological archive for finding hints of paleoclimatic conditions during its formation period.
