Pure sulfur discovered in Gediz Vallis on Mars
NASA’s Mars Rover Curiosity found a Martian rock containing crystals of elemental sulfur, which means it’s pure sulfur. In the past, in the same area, the Gediz Vallis channel’s area, the presence of sulfur in various compounds was detected but it’s the first time that it was detected in its pure form. It’s such an anomaly that its discovery was compared to that of an oasis in the desert. A field with stones made of pure sulfur shouldn’t exist on Mars, and scientists following Curiosity’s exploration of Mount Sharp, at the center of Gale Crater, will have more work to do to explain its formation.
