Mars Studies Map Buried Ice Probabilities for Crewed Missions, Highlighting a 1-5 Meter Data Gap

Summary
Two Planetary Science Journal papers produced the clearest map yet of buried Martian ice in the mid-latitudes, where crews would likely land and need water directly beneath them.
Samuel Courville's team turned conflicting ice-detection signals into location-by-location probabilities—such as a 64% chance of ice—giving mission planners a usable measure of risk instead of raw model agreement.
Hanna Sizemore's group compared three independent maps from orbital thermal data and treated their disagreements as warning zones—useful targets for robots, but poor candidates for human landings.
The maps matter because subsurface ice could supply drinking water, oxygen and return-mission propellant on Mars, sharply reducing the mass that must be launched from Earth.
A major blind spot remains at 1 to 5 meters deep—the practical excavation range for astronauts—because current thermal methods probe only the top meter and radar works mainly beyond 5 meters.
