The Mars Odyssey neutron spectrometer observations indicate that if all the ice in the top meter of the Martian surface were spread evenly, it would give a Water Equivalent Global layer (WEG) of at least ≈14 centimetres (5.5 in)—in other words, the globally averaged Martian surface is approximately 14% water. [226]
However, early in its history Mars may have had conditions more conducive to retaining liquid water at the surface. Mars without a dust storm in June 2001 (on left) and with a global dust storm in July 2001 (on right), as seen by Mars Global Surveyor. Early Mars had a carbon dioxide atmosphere similar in thickness to present-day Earth (1000 hPa ...
There may be much more water further below the surface; the instruments aboard the Mars Odyssey are only able to study the top meter or so of soil. If all holes in the soil were filled by water, this would correspond to a global layer of water 0.5 to 1.5 km deep. [9] The Phoenix lander confirmed the initial findings of the Mars Odyssey. [10]
Currently, the Perseverance rover is climbing the rim of Jezero Crater on Mars, an ancient lake once filled with water 3.7 billion years ago. Some of the rocks the rover has encountered may have ...
LOS ANGELES (Reuters) -NASA's rover Perseverance has gathered data confirming the existence of ancient lake sediments deposited by water that once filled a giant basin on Mars called Jerezo Crater ...

Radar from the Mars Reconnaissance Orbiter gave a strong reflection from the top and base of LDAs, meaning that pure water ice made up the bulk of the formation (between the two reflections). [ 49 ] [ 50 ] Based on the experiments of the Phoenix lander and the studies of the Mars Odyssey from orbit, frozen water is now known to exist at just ...
Mars's surface was once lush with water. Heck, the Perseverance rover is exploring a basin that used to be a giant lake and river delta . But the planet didn't have a strong magnetic field, like ...
