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 like the world is crammed with it. It’s an sudden discovery — whereas minerals containing sulfur have been noticed on the Pink Planet, elemental sulfur by itself has by no means been seen there earlier than. “It types in solely a slender vary of circumstances that scientists haven’t related to the historical past of this location,” in line with .
Curiosity cracked open the rock on Might 30 whereas driving in a area often called the Gediz Vallis channel, the place comparable rocks had been seen throughout. The channel is believed to have been carved by water and particles flows way back. “Discovering a area of stones fabricated from pure sulfur is like discovering an oasis within the desert,” mentioned Ashwin Vasavada, Curiosity’s challenge scientist. “It shouldn’t be there, so now we have now to clarify it. Discovering unusual and sudden issues is what makes planetary exploration so thrilling.”
After recognizing the yellow crystals, the staff later used a digicam on Curiosity’s robotic arm to take a more in-depth look. The rover then took a pattern from a unique rock close by, because the items of the rock it had smashed had been too brittle for drilling. Curiosity is supplied with devices that permit 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.
