Curiosity Sends a Postcard From Mount Sharp’s Boxwork Region

NASA’s Curiosity Mars rover used its black-and-white navigation cameras to capture panoramas at two times of day on Nov. 18, 2025, spanning periods that occurred on both the 4,722nd and 4,723rd Martian days, or sols, of the mission. The panoramas were captured at 4:15 p.m. on Sol 4,722 and 8:20 a.m. on Sol 4,723 (both at local Mars time), then merged together. Color was later added for an artistic interpretation of the scene with blue representing the morning panorama and yellow representing the afternoon one. The resulting “postcard” is similar to ones the rover took in June 2023 and November 2021. Adding color to these kinds of merged images helps different details stand out in the landscape. The scene captured in this postcard shows Curiosity at the top of a ridge referred to as a boxwork formation. These formations crisscross a region in the lower foothills of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain which Curiosity has been climbing since 2014. Curiosity used the drill on the end of its robotic arm to collect a rock sample from the top of this ridge at a spot nicknamed “Nevado Sajama.” This view looks north across the boxwork formations and downslope of Mount Sharp toward the floor of Gale Crater, a vast impact crater the mountain is located within. The crater’s rim can be seen far in the distant horizon, approximately 25 miles (40 kilometers) away. Wheel tracks are visible in the hollow behind Curiosity, where a sample was also drilled at a spot nicknamed “Valle de la Luna.” The boxwork formations are believed to have been created billions of years ago when water on ancient Mars dripped through rock cracks, carrying minerals with them. The minerals hardened after the water dried up; eons later, wind sandblasted the softer rock around these hardened minerals, exposing the ridges Curiosity is exploring today. These ridges may reveal more about the planet’s watery past. 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 as part of NASA’s Mars Exploration Program portfolio.
