The US space agency (Nasa) has reported that its Curiosity rover has made another significant discovery on Mars.

The robot has drilled into a rock that contains clay minerals - an indication of formation in, or substantial alteration by, neutral water.

Scientists say the find is one more step towards showing conditions on the Red Planet in the distant past could have supported life.

Many rocks studied previously were probably deposited in acidic water.

While this would not have precluded the possibility of micro-organisms taking hold on Mars, it would have been more challenging, scientists believe.



Well, this is interesting. I guess life could have taken hold more easily in neutral water than acidic water, but I wonder whether it did?
