NASA's Curiosity Rover Investigates 'Erosional Supersurface' on Mount Sharp
NASA
- NASA's Curiosity rover is studying a potential "erosional supersurface" on Mount Sharp, a geological feature indicating a significant break in the rock record.
- An erosional supersurface occurs when wind or water strips away sediment layers across a region before new material is deposited.
- The mission team is using a suite of onboard instruments to analyze the composition and geometry of these rock layers at a centimeter scale.
Scientific Investigation
- Curiosity has spent the current week climbing Mount Sharp to reach this feature, which was previously identified via orbital data and imaging.
- The rover captured detailed Mastcam mosaics and utilized ChemCam RMI images to document the structure.
- On-site composition analysis included target rocks "Monte Darwin," "Patacamaya," "Tarucachi," and "Mojoncasa" using MAHLI, APXS, and ChemCam LIBS instruments.
Traversal Strategy
- The science team carefully selected a crossing point for the rover based on imaging data.
- Factors influencing the path include the scientific interest of the area and the navigation challenges posed by sandy, steeply sloping terrain.
- Rover operations are currently aimed at positioning the vehicle at the base of the layer for a future ascent over the supersurface.
