READ MORE: NASA may be edging NASA 's Curiosity rover has made a 'mind-blowing' discovery on Mars that scientists said 'should not be there.'
The one-ton rover uncovered yellowish-green crystals of pure sulfur during its search for chemical evidence that the Red Planet was once habitable Curiosity's project scientist, Ashwin Vasavada, said: 'Finding a field of stones made of pure sulfur is like finding an oasis in the desert. When combined with other elements, sulfur gives off a pungent smell, but the pure sulfur found on Mars is odorless.
'I have to say, there's a lot of luck involved here. Not every rock has something interesting inside.' But the group seen on Mars had been sandblasted for millions of years, which dulled the bright yellow and made them appear reddish like the surrounding landscape. The goal has been to develop a better understanding of how this landscape changed billions of years ago, and recent clues have provided insights.
