Sols 4178-4179: The Pinnacle Ridge Scarp
Earth planning date: Monday, May 6, 2024
Curiosity’s set of complex activities and drive over the weekend executed perfectly and we started our planning today directly in front of a scarp, or wall, along a section of the upper Gediz Valis ridge known as “Pinnacle Ridge.” The view along this scarp did not disappoint!
Mastcam planned a large mosaic to image the top and bottom of the Pinnacle Ridge scarp, complementing the Mastcam mosaic that was acquired over the weekend. ChemCam included a long distance RMI image of the face of the ridge with intriguing tonal and textural variations. The targeted science block on sol 4178 also includes a MAHLI mosaic of an interesting layered rock in our workspace, “El Portal,” that will be characterized and imaged by ChemCam LIBS and Mastcam. Lastly, Mastcam will take a small mosaic of a rock in the workspace, “Bairs Creek,” to investigate interesting textures and features that were created by the wind.
In the untargeted science block on sol 4179, the environmental theme group planned several activities including a Mastcam sky survey, a dust devil movie and survey, and a suprahorizon movie to observe dust and cloud activity in Gale. ChemCam included an AEGIS activity where the rover will pick and analyze a target in the workspace after Curiosity completes a ~32-meter drive. Although the large, tilted rocks ahead make for a challenging drive, excitement is running high as we continue our ascent along the margin of the upper Gediz Vallis ridge!
