NASA’s Curiosity Mars rover used its Mast Camera, or Mastcam, to capture this last look at a field of bright white sulfur stones before leaving Gediz Vallis channel.

The field was where the rover made the first discovery of pure sulfur on Mars by driving over a rock and cracking it open to reveal the yellow crystals inside. Scientists are still unsure exactly why these pure sulfur rocks formed here. This panorama is made up of eight images captured on Oct. 11, 2024, the 4,331st Martian day, or sol, of the mission.

The color has been adjusted to match lighting conditions as the human eye would see them on Earth.

Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington.
