The panorama gives scientists their closest look yet at mysterious yardang formations that may hold clues to ancient volcanic or wind processes on Mars.

NASA's Curiosity rover has captured a detailed panorama of wind-sculpted cliffs called yardangs on Mars, taken in early morning light that gives the image unusual blue tones. The six-image panorama, shot by Curiosity's Mastcam, was left unprocessed for white balance so it would retain its natural dawn appearance.

The yardangs sit along the northwestern edge of Mount Sharp, a towering mountain Curiosity has been climbing since 2014. The rover recently reached its highest elevation yet on the mountain, a milestone that also represents the greatest height any rover has climbed on Mars.

Mount Sharp's layered terrain records different chapters of the planet's past, including evidence of ancient lakes and streams that eventually dried up, leaving mineral deposits behind. Scientists believe the yardangs may have formed when wind stripped away material after sediment stopped accumulating on the mountain.

Project scientist Ashwin Vasavada of NASA's Jet Propulsion Laboratory noted that the yardang layer stands out because of its unusual color, tilted layering, and texture, which make it look almost out of place compared to surrounding rock. He suggested the layer could be remnants of ash from ancient volcanic eruptions, though its origin remains unconfirmed.

Curiosity is currently in its fifth extended mission, following earlier exploration of unusual ridge formations. The rover will spend much of the coming year traveling through terrain rich in sulfates and carbonates, minerals that point to long-ago drying on the Martian surface.

Mission scientists expect Curiosity to reach the base of the yardangs around 2027, at which point it could use its robotic arm to gather direct data on the formations, potentially resolving longstanding questions about how they came to be.
