Sulfur Crystals on Mars: Curiosity’s Happy Accident

Scientists were stunned when a wheel on the Curiosity Mars rover recently cracked open a rock to reveal something never seen before on the Red Planet: yellow sulfur crystals. While the rover has previously detected sulfur-based minerals, this rock is made of pure, elemental sulfur. Join us for a live conversation with Dr. Ashwin Vasavada, Curiosity’s project scientist, to discuss the significance of the finding as well as other notable discoveries from the mountain-climbing Mars explorer’s 12th year on the Red Planet.
