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 seems to be like the realm is stuffed with it. It’s an surprising 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 forms in only a narrow range of conditions that scientists haven’t associated with the history of this location,” in accordance with .
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 believed to have been carved by water and particles flows way back. “Finding a field of stones made of pure sulfur is like finding an oasis in the desert,” stated Ashwin Vasavada, Curiosity’s undertaking scientist. “It shouldn’t be there, so now we have to explain it. Discovering strange and unexpected things is what makes planetary exploration so exciting.”
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 special rock close by, because the items of the rock it had smashed had 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.
