The Curiosity rover on Mars has made a surprising discovery of rocks made of pure sulfur. While driving, the rover accidentally cracked open a rock, revealing yellowish-green crystals that have never been seen on Mars before. The find has been described as the most unexpected and strangest of the entire mission. The team is now looking to understand what the presence of pure sulfur on Mars means for the planet’s history. The discovery adds to the rover’s findings of habitable environments on Mars and contributes to its mission of exploring the planet further.
