Researchers conclude that a nearshore zone once existed in Utopia Planitia.
Mars may have oceans' worth of water — but it's more than 10 km under the surface.
Liquid water on ancient Mars seems to be essentially confirmed now.
It's still pretty neat... but not as exciting as water.
There's more to the Red Planet than you think.
The melting of ice beneath the surface of Mars could have made its deep regions the most habitable.
We absolutely need this if we're to ever establish a colony on the Red Planet.
For billions of years, Mars has had quite the leak.
This has been a tremendous month for discoveries on the inner planets.
Mars' past seems to be more and more interesting.
Curiosity is finding water beneath the ground -- and in the sky.
This study offers a vital answer, but also poses a puzzling question.
It's a hint that Mars had a wet past.
We don't know whether Mars held life... but there's certainly a lot of potential.
Can't have a devastating water wave without water!
Water on Mars? Yes please!
Mars is now a cold and dry place, but it wasn't always like this - the Red Planet used to have a lot of water on its surface. Now, researchers have discovered one of the very last places where (potentially habitable) liquid water existed on Mars.
Researchers have long known that Mars has water in the form of ice, but now, after years and years of research, we might finally have the decisive clue that our planetary neighbor has liquid water on its surface. The key find was perchlorate - a substance that significantly lowers the freezing point, so that water doesn't freeze into ice, but remains liquid and briny.
Intricate polygons on Mars could be a clear indication of a wet past for the Red Planet. Most crater floor polygons have diameters ranging from 15 to 350 m, and it’s still not clear how and why they appeared – though one theory seems to be gaining ground: the idea of former lake beds. Polygons […]
Researchers have reported dark streaks near the equator of Mars, hinting at surprisingly large quantities of flowing water. If true, this could be extremely important for life on Mars, and potentially even establishing research bases. Water on Mars – yes If you don’t know that rivers and lakes were fairly common on Mars a long […]
NASA’s Curiosity rover has come up with yet another remarkable discovery – evidence of an ancient, freshwater lake, with water that was likely very similar to that of today’s Earth lakes. The feature is thought to be part of a longstanding aquatic environment which could have supported simple life forms. “In March, we did know […]
A study conducted by researchers from the Carnegie Institution for Science concluded that both Earth and Mars got their water from the same source chondritic meteorites. However, unlike Earth, Martian rocks containing atmospheric volatiles such as water don’t get recycled into the planet’s deep interior. The origin, history, and evolution of Martian water are […]
Several studies performed in the last decade have shown Mars used to be warmer and wetter, but scientists still haven’t figured out exactly why we are seeing these clues and how our red neighbor used to look like ages ago. Now, a new study concluded that Mars was much, much wetter than previously believed and […]
NASA’s famous rover, Opportunity, seems to have stumbled upon clear evidence that water used to flow on Mars, a long long time ago. Opportunity was prowling around the Meridiani Planum on Mars, looking at hematite (an iron oxide) when it stumbled upon something which delighted researchers: gypsum. Why is this vein of gypsum so important […]
