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 world is full of it. It’s an sudden discovery — whereas minerals containing sulfur have been noticed on the Crimson Planet, elemental sulfur by itself has by no means been seen there earlier than. “It varieties in solely a slender vary of circumstances that scientists haven’t related to the historical past of this location,” based on .
Curiosity cracked open the rock on Might 30 whereas driving in a area often known as the Gediz Vallis channel, the place related rocks had been seen throughout. The channel is assumed to have been carved by water and particles flows way back. “Discovering a discipline of stones made from pure sulfur is like discovering an oasis within the desert,” mentioned Ashwin Vasavada, Curiosity’s mission scientist. “It shouldn’t be there, so now we now have to elucidate it. Discovering unusual and sudden issues is what makes planetary exploration so thrilling.”
After recognizing the yellow crystals, the workforce later used a digital camera 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 provided with devices that permit it to research the composition of rocks and soil, and NASA says its Alpha Particle X-Ray Spectrometer (APXS) confirmed it had discovered elemental sulfur.
