   Mars contains water, though mostly as permafrost. As top surface layer water appears readily visible at some places, such as the polar Korolev Crater. Almost all water on Mars today exists as polar permafrost ice, though it also exists in small quantities as vapor in the atmosphere. [1]

   How long has water been on Mars?

   • But two scientists studying data that MRO has accumulated at Mars over the last 15 years have found evidence that reduces that timeline significantly: Their research reveals signs of liquid water on the Red Planet as recently as 2 billion to 2.5 billion years ago, meaning water flowed there about a billion years longer than previous estimates.

   Is there liquid water on Mars?

   • Analysing those quakes - and exactly how the planet moves - revealed "seismic signals" of liquid water. While there is water frozen at the Martian poles and evidence of vapour in the atmosphere, this is the first time liquid water has been found on the planet. The findings are published in the Proceedings of the National Academy of Sciences.

   When did Mars' water evaporate?

   • As the planet’s atmosphere thinned over time, that water evaporated, leaving the frozen desert world that NASA’s Mars Reconnaissance Orbiter (MRO) studies today. It’s commonly believed that Mars’ water evaporated about 3 billion years ago.

   Does water flow intermittently on Mars?

   • Editor’s note: The findings described in this press release were updated with additional research published on Nov. 20, 2017, and described in ” Recurring Martian Streaks: Sand, not Water?” New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars.

   Is Mars 'following the water'?

   • “Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington.

   Why is water on Mars important?

   • Water on Mars also has important implications for research areas at beyond the work of the Astrobiology Program. Even if life no longer lives on Mars, or never existed in the first place, water could still prove vital to future life on Mars in the form of human colonies on the red planet.
