NASA’s Curiosity rover has resumed its regular operations on Mars after a brief detour to explore an erosional surface. This week, spanning Sols 4982 to 4985, Curiosity focused on geological features and environmental monitoring as it continues its ascent of Mount Sharp.
Geological Imaging and Analysis
On August 12, 2026, Curiosity captured an image of thin, ledge-like layers at the target named “Los Toldos” using its Right Mast Camera (Mastcam). This image was taken at 01:05:04 UTC during Sol 4982, marking a significant moment in the Mars Science Laboratory mission.
During this period, the rover utilized its MAHLI (Mars Hand Lens Imager) to reacquire images for a mosaic of the target “Tres Morros,” providing a detailed view of the underside of this geological feature. Additionally, the APXS (Alpha Particle X-ray Spectrometer) conducted measurements on the bedrock target “El Motacusal” after it was brushed with the DRT (Dust Removal Tool), followed by a second measurement on the “as is” bedrock target “Alto de Carmen.” High-resolution images of both targets were captured by MAHLI.
Remote Sensing and Environmental Monitoring
The rover’s ChemCam (Chemistry and Camera) performed LIBS (Laser-Induced Breakdown Spectroscopy) on bedrock targets “Lagunas Bravas” and “Parququcha,” along with Remote Micro-Imaging on “Mishe Mokwa.” The Mastcam also produced a near-field mosaic of the erosional ridge, “Los Toldos,” and documented previous ChemCam activities.
On August 14, Curiosity drove 100 feet (30 meters) to a new location for Sols 4985 to 4987. Although the rover encountered challenges positioning its robotic arm due to a small rock under its left-front wheel, it successfully performed contact science on two bedrock targets, “Mamorecillo” and “Aguas Claras.” MAHLI also imaged a calibration target during this time.
Atmospheric Observations
Environmental monitoring was a key focus during this week. The Mastcam conducted multiple dust-imaging observations to measure the optical depth, or “tau,” of the Martian atmosphere, indicating the amount of dust present. A higher tau value correlates with increased atmospheric dust. The APXS planned an overnight atmospheric measurement, while the Navcam (Navigation Camera) conducted extensive dust-devil surveys and other observations to monitor for potential dust storms.
As Curiosity continues its climb up Mount Sharp, a planned drive distance of 150 feet (47 meters) will take the rover southwest of its current location. The mission team anticipates a week filled with contact science, remote sensing, and further exploration on Mars.
