Curiosity Rover finds clay cache on Mars — potential sign of water

Curiosity is finding water beneath the ground — and in the sky.

Mars had giant rivers for billions of years, new study finds

This study offers a vital answer, but also poses a puzzling question.

Curiosity photographs river-like rounded rocks

It’s a hint that Mars had a wet past.

Curiosity rover finds that its landing crater on Mars could have been habitable for 700 million years

We don’t know whether Mars held life… but there’s certainly a lot of potential.

Geological deposits hint at ancient ocean on Mars’ surface

Can’t have a devastating water wave without water!

Water on Mars? Yes please!

Scientists find the last vestiges of Martian surface water

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.

There’s a good chance Mars has liquid water

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.

The Martian Polygons – An evidence for former Seafloors?

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 are some of the most common

Flowing water found on Mars – suggests life exists in the underground

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 time ago, you haven’t been

Evidence of ancient lake found on Mars

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 that we had a lake,

Study: Mars got its water the same place Earth did – meteorites

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 pretty much a hot topic

More evidence shows Mars was wet

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 that its atmosphere was significantly

NASA Opportunity Rover finds traces of flowing water on Mars

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 ? Because this vein could
