These Mars global maps show the likely distribution of water ice buried within the upper 3 feet (1 meter) of the planet's surface and represent the latest data from the SWIM project. Buried ice will be a vital resource for astronauts on Mars, serving as drinking water and a key ingredient for rocket fuel. NASA/JPL-Caltech/PSI
