NASA's Curiosity rover celebrated its 14th landing anniversary on Mars while continuing its scientific investigation of rock layers on Mount Sharp.

NASA’s Curiosity rover recently marked its 14th anniversary since landing on Mars on August 6, 2012. During the week spanning Sols 4975 to 4981, the rover continued its ascent of Mount Sharp, conducting geological investigations and environmental monitoring. Despite navigating steep terrain, the rover successfully reached its planned research location to analyze rock formations and cross-bedding.

Scientific Investigations on Mount Sharp

Curiosity is currently investigating rock layers on Mount Sharp, specifically looking for cross-bedding to understand how different rock strata relate to one another. Recent activities included using the APXS instrument to measure targets such as “Tunas Khasa,” “Villarrica,” “Salar de Gorbea,” and “Uriondo.” The rover also utilized its ChemCam and Mastcam instruments to analyze bedrock and outcrops, including targets like “Lago Rupanco,” “Chulipa Punta,” “La Linea,” and “Tiraque.” Researchers are examining these sites to reconstruct the geological history of the area, which appears to have been shaped by wind and water billions of years ago. The team is also performing housekeeping tasks, such as cleaning the SAM column and imaging the REM UV sensor, alongside ongoing environmental monitoring of dust, atmospheric opacity, and radiation.

Operational Milestones

The rover recently completed a 46-foot (14-meter) drive to reach a location where distinct rock layers intersect. During its climb, the rover encountered slopes with a tilt of up to 24 degrees. The mission team continues to use the RAD instrument to monitor the radiation environment, a task it has performed since the spacecraft's cruise phase following its November 2011 launch.
