NASA scientists say pure sulfur has been discovered on Mars for the primary time after the Curiosity rover inadvertently uncovered a cluster of yellow crystals when it drove over a rock. And it appears to be like like the realm is crammed with it. It’s an surprising discovery — whereas minerals containing sulfur have been noticed on the Purple Planet, elemental sulfur by itself has by no means been seen there earlier than. “It types in solely a slim vary of circumstances that scientists haven’t related to the historical past of this location,” in response to .
Curiosity cracked open the rock on Might 30 whereas driving in a area referred to as the Gediz Vallis channel, the place related rocks have been seen throughout. The channel is believed to have been carved by water and particles flows way back. “Discovering a discipline of stones fabricated from pure sulfur is like discovering an oasis within the desert,” mentioned Ashwin Vasavada, Curiosity’s venture scientist. “It shouldn’t be there, so now we have now to elucidate it. Discovering unusual and surprising issues is what makes planetary exploration so thrilling.”
After recognizing the yellow crystals, the crew later used a digicam on Curiosity’s robotic arm to take a better look. The rover then took a pattern from a unique rock close by, because the items of the rock it had smashed have been too brittle for drilling. Curiosity is supplied with devices that enable it to investigate the composition of rocks and soil, and NASA says its Alpha Particle X-Ray Spectrometer (APXS) confirmed it had discovered elemental sulfur.
