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."
