NASA ’s CuriosityMars roverhas accidentally uncovered an abundance of never - before - consider crystals on the Red Planet after inadvertently running over a rock .
On May 30 , the roverwas exploring Gediz Vallis — a canal carved into the steep side of Mount Sharp in the meat of Gale Crater — when it unexpectedly drove over a little rock , cracking it open . When the rover ’s cameras focused on what the robot had jaunt over , scientists spotted curious yellow crystals gleaming among the stone ’s newly exposed innards .
Yellow crystals of pure, elemental sulfur appear inside a crushed Mars rock that NASA’s Curiosity rover accidentally drove over.
The crystals in the cracked rock were too small and delicate for the roamer to properly plow . But when the robot exercise into another nearby rock , it revealed the crystal were made of pure sulfur .
Sulfur has been detected on Mars before — but only when merge with other element in compound live as sulfates . Until now , pure S , also known as elemental sulphur , had never been found on the Red Planet . scientist suspected there might be primary sulfur somewhere on Mars but were surprised to find oneself it inside surface rocks .
" It should n’t be there , so now we have to excuse it,“Ashwin Vasavada , a Curiosity rover project scientist at NASA ’s Jet Propulsion Laboratory , said in astatement . " distinguish strange and unexpected things is what makes planetal geographic expedition so exciting , " he added .

The rover did n’t confirm the comportment of the yellow crystals in any other rock’n’roll . However , scientist are confident the nearby rock music also contain sulfur , which makes this area a site of pursuit for future study .
" Finding a field of stones made of complete sulfur is like regain an oasis in the desert , " Vasavada enounce .
Curiosity , which landed in the neighborhood in 2012 , has find out several other intriguing rocks in and around Gediz Vallis . In February , the rover snappedphotos of " waves " carved into an ancient lakebedby Martian body of water millions of year ago . And in May , the wandering robotfound rocks containing manganese oxide , which is the best evidence yet that the Red Planet once had an O - copious , worldly concern - like standard pressure .
