Nasa’s Planetary Science Director Jim Green announced that scientists have found traces of liquid water on the red planet, solving the mystery on planet Mars.
702's John Robbie spoke to Professor David Block, the director of the The Cosmic Dust Laboratory at Wits University, about how significant this finding is. Prof Block said this finding is big and the discovery of hydrated salts mixed with water running at certain times of the year is a remarkable find.
EWN earlier reported that researchers analysing data from a Nasa spacecraft had found the first evidence that briny water flowed on the surface of the planet.
Nasa's chief scientist Ellen Stofan said she expected tangible signs that life can be found on the planet within the next decade and definitively in 30 years’ time.
