3 days ago · Most of the water on Mars today is likely frozen away in its polar caps. If all this water ice were to melt, estimates suggest that a sphere the size of the red planet might be covered in about 100 feet (30 meters) of water, said Suniti Karunatillake, a planetary scientist at Louisiana State University in Baton Rouge.

Mar 16, 2021 · The team studied the quantity of water on Mars over time in all its forms (vapor, liquid, and ice) and the chemical composition of the planet's current atmosphere and crust through the analysis of meteorites as well as using data provided by Mars rovers and orbiters, looking in particular at the ratio of deuterium to hydrogen (D/H).
Aug 12, 2024 · Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water — enough to fill oceans on the planet’s surface. The data from NASA’s Insight lander allowed the scientists to estimate that the amount of groundwater could cover the entire planet to a depth of between 1 and 2 kilometers, or about a mile.
Sep 28, 2015 · For Ojha, the new findings are more proof that the mysterious lines he first saw darkening Martian slopes five years ago are, indeed, present-day water. “When most people talk about water on Mars, they’re usually talking about ancient water or frozen water,” he said. “Now we know there’s more to the story.
A fraction of this water is retained on modern Mars as both ice and locked into the structure of abundant water-rich materials, including clay minerals (phyllosilicates) and sulfates. [ 94 ] [ 95 ] Studies of hydrogen isotopic ratios indicate that asteroids and comets from beyond 2.5 astronomical units (AU) provide the source of Mars' water, [ 96 ] that currently totals 6% to 27% of the Earth ...
Aug 12, 2024 · Scientists have discovered a reservoir of liquid water on Mars - deep in the rocky outer crust of the planet. The findings come from a new analysis of data from Nasa’s Mars Insight Lander, which ...

2 days ago · New findings from NASA ’s Mars Reconnaissance Orbiter (MRO) 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 darkish streaks appear to ebb ...
