In a significant breakthrough, NASA's Curiosity Mars rover has uncovered pure sulfur crystals on Mars for the first time. This discovery was made on June 7th, during the 4,208th Martian day (sol) of the mission, and was captured by the rover's Mast Camera (Mastcam). The crystals, which have been nicknamed “Convict Lake” after a site in California’s Sierra Nevada, are approximately 5 inches (13 centimetres) wide.

According to NASA's blog post, the crystals were identified after Curiosity drove over and crushed the rock on May 30. The rover later used its Alpha Particle X-ray Spectrometer, an instrument mounted on its robotic arm, to analyse the rock’s composition. Figure 1 shows NASA has discovered pure sulfur crystals on mars for the first time.

While sulfur compounds have been previously detected on Mars, this is the first time pure elemental sulfur has been found. The area where this discovery was made is known for its abundant sulfate content, which is a type of sulfur-based salt that formed when ancient water evaporated from this region of the Red Planet billions of years ago. “Scientists have observed various sulfur compounds on Mars, but finding elemental sulfur in its pure form is unprecedented,” NASA explained.[1]

On Earth, elemental sulfur forms through geological processes such as volcanic and hydrothermal activity. The discovery of pure sulfur crystals on Mars raises fascinating questions about the planet’s geological history and processes. Scientists are currently investigating the origins of these crystals and are examining the surrounding rocks and the broader area for additional insights.[2]

For context, Curiosity was developed by NASA's Jet Propulsion Laboratory (JPL), which is managed by Caltech in Pasadena, California. JPL leads the mission under NASA's Science Mission Directorate in Washington. The Mastcam, which captured the images of the sulfur crystals, was built and is operated by Malin Space Science Systems in San Diego.
