Daily MailNASA's Curiosity rover has made a 'mind-blowing' discovery on Mars that scientists said 'should not be there.' Curiosity accidently cracked opening white stones as it traveled through the Gediz Vallis channel, revealing the 'strange' structures that add to the growing evidence that Mars was once a habitable world. The one-ton rover uncovered yellowish-green crystals of pure sulfur during its search for chemical evidence that the Red Planet was once habitable Previous research has suggested that sulfur may have played a key role in the origin of life on Earth more than four billion years ago when the atmosphere was rich in sulfur and carbon, which was emitted through volcanic activity. The rover sent a close-up image of the white stones back to Earth, which included an ear of crushed rocks near Curiosity's wheels. Curiosity made the strange find by accidently cracking opening white stones as it traveled through the Gediz Vallis channel 'I have to say, there's a lot of luck involved here.
