NASA's Curiosity rover has reached a new elevation on Mars, investigating a geological discontinuity that marks a shift in the planet's ancient environmental history.
Key facts
- •Curiosity reached a 24-degree tilt while climbing to the top of the “Cerro Paine Grande” outcrop.
- •The rover is investigating an “erosional supersurface” that marks a discontinuity in the Martian rock record.
- •On Sol 4972, the rover used its MAHLI camera to capture the “Longquimay” mosaic of sedimentary textures.
- •Science teams targeted several bedrock blocks, including “Puyehue,” “Lago Palena,” and “Sierra de Sangre,” for detailed analysis.
- •The rover also performed atmospheric measurements, including monitoring atmospheric opacity and minor gas abundances.
NASA’s Curiosity rover recently completed a steep climb to reach a geological feature in Gale Crater known as an “erosional supersurface.” The rover is currently investigating this area, which represents a historical transition between depositional and erosional environments on Mars. During the mission's 4,968th through 4,972nd sols, the rover utilized its robotic arm and camera systems to document sedimentary textures and rock layers.
By the numbers
Investigating the Supersurface
The “supersurface” is a significant feature in the sedimentary record, indicating a period where the environment shifted from depositing material to eroding it, before eventually returning to a depositional state. Scientists suspect this erosion may have been caused by wind, water, or a combination of both. Curiosity is currently analyzing patterns that appear consistent with aeolian features and fluvial “lens” deposits to better understand these environmental changes.
Climbing and Contact Science
To reach the top of the “Cerro Paine Grande” vertical exposure, the rover performed a challenging climb that left it parked at a 24-degree tilt. This maneuver nearly reached the mission's contact science tilt record of 27 degrees. Once in position, the rover used its Mars Hand Lens Imager (MAHLI), Alpha Particle X-ray Spectrometer (APXS), and Chemistry and Camera (ChemCam) instruments to characterize the bedrock and analyze the composition of local sand.
