NASA/JPL-Caltech Written by Benjamin Tutolo, Professor, University of Calgary Earth planning date: Friday, Sept. 4, 2026 Curiosity has marked several huge milestones (14 years on Mars; 5,000 sols on Mars; 1 kilometer of elevation gain since landing) over the past several weeks, and the team has duly celebrated these remarkable achievements. These celebrations punctuate the rover’s otherwise very busy and data-filled exploration of Mount Sharp, of which this week was another in a long succession of discoveries. The team planned instrument activities that involved unstowing the arm on Sols 5003 and 5004 to continue investigations of the wind-formed long, narrow large ripple “Chocolatal” (see last week’s blog: “Curiosity Blog, Sols 4995-5001: 5,000 (Martian) Days on Mars”), followed by a short drive on sol 5004. Planning for the arm activities on Monday was complex, with APXS chemical analyses and MAHLI imaging of targets within the wheel scuff and on top of the undisturbed ripple (seen in the image above), and a MAHLI “Dog’s Eye” image mosaic acquired on the way of the scuff. The team worked hard developing the plan for these arm activities this Monday due to the particular complexity of the MAHLI “Dog’s Eye” mosaic image. While the MAHLI instrument is frequently used to image features on the Martian surface from above, Dog’s Eye mosaics are reserved for targets we want to see edge-on, similar to how a dog close to ground may view a surface. In this instance, the team was interested in looking at potential layers visible on the sides of the sand scuff. The end-of-week plan for activities over the Labor Day weekend in the United States and here in Canada includes APXS, MAHLI, and ChemCam analyses of the interesting gray stone that caught the team’s collective eye. Interestingly, the bedrock surrounding this stone appears to contain large nodules, which we have not seen for some time. The Mastcam instrument will be pointed back toward the Chocolatal area, and ChemCam will image and collect a couple of other LIBS observations on several interesting patches of the local geology.
