Evidence of drinkable water found on Mars

NASA's aged Opportunity rover is still proving its value after making a new discovery about early water.

The solar-powered rover which has been on Mars now for almost 10 years came across what is believed to be its oldest rock discovery yet. Nicknamed 'Esperance 6', the rock shows evidence that potentially life-supporting water once flowed on the Red Planet in abundance, leaving behind a high concentration of clay.

"This is powerful evidence that water interacted with this rock and changed its chemistry, changed its mineralogy in a dramatic way," said investigator Steve Squyres. The discovery is yet further evidence to support the notion that Mars was once a water-rich world in which primitive life forms could have developed and survived.

"Nasa scientists say their Opportunity rover has made new discoveries about early water on Mars which may have been drinkable."

The headline is rather misleading. Yes there may have been drinkable water on Mars in the past, but now it's a veritable planet-wide dust bowl.

I still think its an important and intriguing discovery, remember is 'just' a mechanical and old rover up there, amazing it still works to be honest.. and yes we all want to know about life up there, but lets give the new rover time!!! How much could you 'explore' and learn about if you moved just a few meters a day?

Indeed, I think the Mars rovers, past, present and future, will discover things(such as ancient marine fossils/micro-fossils) that will amaze us all. That's my hope, anyway.

They either wont investigate such things, or wont let us know about them. They have not shown the public any interest in unusual objects so far. They have set objectives, drilling rocks and digging clay. They stick to these.

After seeing some of the evidence on Mars, I agree with Colonel Rhuairidh. I believe Mars was our home at one time. maybe Mars is a warning.

This is very cool, what a time to be alive! I have no doubts that the universe is teaming with life and soon there will be proof that two planets in one solar system had life at one point. With how violent and unpredictable the universe is I'm not sure that there's a lot of intelagent life out there but who knows the crazy creatures that roam planets we'll probably never know exist.

This is old news. The discovery that some water on Mars may once have been neutral (as opposed to acidic) and therefore drinkable was made back in March by Curiosity (see ). This Opportunity discovery is just confirmation of that discovery. Previously rock deposits had shown signs of acidic water, which is not great for life.

Using your logic, proving that you are capable of firing a gun is surely proof that you are a murderer. Proving that life could have existed and Mars can not in any way be considered proof that it MUST have existed on Mars. With only one example of a planet with life so far (the Earth, obviously) we simply do not know how often life emerges. However, the proof that life could have existed strengthens the justifications for future missions which will search for signs of life past or present. This very story shows that they ARE investigating such things and they ARE letting us know about th... [More]

But what about the little monkey,and Dates that grow underground ? THe Lakes. and Rivers that flow underground ? THe Martian Slaves and Invaders ? back to sleep now to late for any more history lessons !
