Martian glaciers are mostly pure ice

Martian glaciers are composed of up to 80% pure ice, offering a potential water source for future explorers. New NASA radar data analyzed five Martian locations, revealing significant ice deposits beneath dust and rock layers, suggesting a common glacial structure across the planet. This discovery, published in Icarus, could be crucial for human missions to Mars, with scientists planning further studies of Martian glaciers to understand the planet's climate and water cycle.
