ACCIDENTALLY EXPOSED YELLOWISH-GREEN CRYSTALS REVEAL ‘MIND-BLOWING' FINDING ON MARS, SCIENTISTS SAY

Summary from the TLDR newsletter

The Curiosity rover has discovered rocks made of pure sulfur. The discovery was made by accident after the 1-ton rover drove over a rock and cracked it open, revealing yellowish-green crystals. On Earth, pure elemental sulfur is mostly found in places like hydrothermal vents. The rock was discovered in an area that was likely formed due to violent water flows and landslides. Curiosity is still in great health after 12 years of service.
