Ice cliffs found Mars

Bands of ice have been spotted on steep Martian cliffs, exciting news for current geologists and future colonists. Ice on Mars is old news, but the exact depth and details about its makeup have been elusive. The Mars Reconnaissance Orbiter (MRO) spotted cliffs of ice, offering geologists a potential trove of information. Future human colonists will have an easier time accessing such water sources, for use in creating essentials like oxygen and rocket fuel. The cliffs found are in relatively frigid regions of Mars, but the search is on for exposed cliffs in a more habitable area.
