The Curiosity rover has found the best evidence yet that Mars was once a habitable planet.
The rover made the discovery by collecting rock samples using its on-board drilling tool and analyzing them using its science instruments. What it found was that the rock contained clay minerals, a clear indication of the presence of neutral water. Ultimately the discovery suggests that at some point in the past there were at least some areas of Mars capable of supporting life as we know it.
"We have found a habitable environment that is so benign and supportive of life that probably if this water was around and you had been there, you would have been able to drink it," said project scientist John Grotzinger.
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.
