We know that lakes existed on Mars’ surface billions of years ago. But scientists have debated whether the lakes were open to the air or covered by a layer of ice.
The research suggests that the thick crust of Mars' southern highlands formed billions of years ago generated granitic magmas and sustained vast underground aquifers.
The history of water on early Mars is not certain. Determining when water first appeared, where and for how long, are all burning questions that drive Mars exploration.
According to a new analysis of the Lafayette Meteorite, minerals within it formed in the presence of water 742 million years ago. It's a real breakthrough in the dating of aqueous minerals on Mars.
A Chinese rover has brought forth evidence that hints at the likelihood of a massive ocean, covering almost a third of the Red Planet, that existed billions of years ago.
New data about the Martian crust gathered by NASA's InSight lander allowed geophysicists to estimate that the amount of groundwater could cover the entire planet to a depth of between 1 and 2 km.
Morning images show frost briefly coating at least four colossal volcanoes: Olympus Mons, Arsia Mons, Ascraeus Mons, and Ceraunius Tholus.
If life ever existed on Mars, the Perseverance rover’s verification of lake sediments at the base of the Jezero crater reinforces the hope that traces might be found in the crater.
ESA's Mars Express has revisited one of Mars's most mysterious features to clarify its composition. Its findings suggest layers of water ice stretching several kilometers below ground—the most water ever found in this part of the planet.
New observations of mud cracks made by NASA's Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments.
French researchers suggesting that the tallest volcano in Solar System, Olympus Mons on Mars was once a volcanic island, surrounded by a deep sea.
A recent study finds that the vast subsurface fracture networks in Gale crater would have provided water-rich and radiation-shielded conditions that were potentially more habitable than those on the surface.
A new research is lending support to the possibility that an asteroid slammed into Martian ancient ocean 3.5 billion years ago, creating a mega-tsunami 309 meters high.
A recently released set of topography maps provides new evidence for an ancient northern ocean on Mars. The maps offer the strongest case yet that the planet once experienced sea-level rise consistent with an extended warm and wet climate.
According to new evidence obtained by the orbiter element of the joint European-Russian ExoMars mission, there is plenty of water ice at the bottom of Valles Marineris mixed with Martian soil - regolith.
