Confirmation of ancient lake on Mars builds excitement for Perseverance rover's samples

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. 

Mars Express finds evidence of large water deposits

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.

Early Mars Had a Sustained, Cyclic, Possibly Seasonal, Climate

New observations of mud cracks made by NASA's Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments.

Mars' Olympus Mons volcano could have been an island

French researchers suggesting that the tallest volcano in Solar System, Olympus Mons on Mars was once a volcanic island, surrounded by a deep sea.

Curiosity rover discovers water-rich fracture halos on Mars

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 mega-tsunami on ancient Mars

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.

Traces of ancient ocean discovered on Mars

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.

Water At The Bottom of Valles Marineris on Mars

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.

Brief presence of water in Arabia Terra on Mars

U.S. scientists recently discovered that water was once present in a region of Mars called Arabia Terra.

Rover confirms existence of ancient Mars lake and river delta

The first research paper from Perseverance rover team was published lately. It shows that Jezero Crater on Mars was probably the site of some violent floods.

A Map of Mars' Entire Ancient River Systems

Three to four billion years ago, Mars did in fact have running rivers of water. Now, scientists have mapped out an entire ancient river system.

Mars once had salt lakes similar to Earth

According to an international team of scientists, the lake that was present in Gale Crater over 3 billion years ago underwent a drying episode, potentially linked to the global drying of Mars.

Curiosity confirms clay deposits on slopes of Mount Sharp on Mars

Clay often forms in the presence of water – a key ingredient for the evolution of life as it is known on Earth – and Curiosity’s latest findings add more evidence that a significant amount of water once pooled and flowed in Gale Crater on Mars.

An Astounding Amount of Water Discovered on Mars

Scientists detected a massive reservoir of frozen water sandwiched by layers of sand beneath the northern polar ice cap on Mars. This reservoir contains so much ice that, if melted and brought to the surface, it would submerge the entire planet.

Signs that Ancient Rivers Flowed Across the Surface of Mars

There’s a massive, growing wall of evidence showing that Mars may have had the necessary conditions for life in the past. ESA’s High-Resolution Camera on the Mars Express Orbiter, there are clear signs of a system of river valleys.
