Curiosity on the Road to Boxwork Formations


NASA's Curiosity Mars rover used its Mast Camera, or Mastcam, to capture this panorama in morning light on March 9, 2025, the 4,476th Martian day, or sol, of the mission. Steep hills on the left side of the panorama enclose wind-carved valleys on Mount Sharp, the mountain that Curiosity has been climbing for over a decade. Broken-up, rounded rocks throughout the foreground are part of the mountain's sulfate-bearing unit.

The butte in the distance at right is nicknamed "Gould Mesa." A band of cliffs and dark ridges near the top of the butte may be the first glimpses of boxwork formations, a kind of feature created by groundwater flowing through large bedrock fractures in the ancient past. Assuming that is how they formed, these could represent the last gasps of water found on this region of Mars before the planet dried out completely.

The color in these images has been adjusted to match the 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. Malin Space Science Systems in San Diego built and operates Mastcam.
