During a news conference at NASA headquarters today, agency scientists and officials discussed new findings from the Mars Reconnaissance Orbiter (MRO) that provide the strongest evidence yet that liquid water flows intermittently on present-day Mars.

Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These downhill flows, known as recurring slope lineae (RSL), often have been described as possibly related to liquid water.
