|Liquid Water on Mars|
NASA photographs have shown brine flowing across the Martian surface over time, specifically on Olympus Mons. This salty water is thought to be formed when geothermal activity heats ice to the point of melting. As the water melts it dissolves salts that can keep it liquid in the low pressure and low temperature conditions on Mars. It is believed to be the first time we have observed changes caused by liquid water on Mars directly.
