# NASA Curiosity Rover Enters Power-Saving Phase During Nazca Drilling Campaign Curiosity pauses intensive drilling operations to recharge batteries while testing new power-saving communication protocols. - **Source:** [NASA](https://www.nasa.gov) - **Published:** 2026-11-10 - **Topic:** [science](https://brifing.si/c/science) - **Original article:** - **On Brifing:** https://brifing.si/s/c8108655-be6b-452b-ba32-226b13dd4e3d ## Operational Power Management NASA’s Curiosity rover is currently undergoing a planned recharging phase covering sols 5060 to 5062. This pause follows intensive drilling activities at the Nazca target site. The team intentionally limited the rover's activity schedule to ensure a power-positive state, allowing the vehicle to recover energy levels before resuming complex scientific operations. ## Nazca Drilling Campaign Status The ongoing campaign at the Nazca site has already successfully completed the initial drilling and sample drop-offs to the SAM and CheMin instruments. Remaining tasks include a specialized drill-shaking procedure known as RAGE to clear residual samples. Engineers must also conduct further imaging of the drill hole and surrounding tailings for documentation. ## Remote Science During Recharge Despite the focus on energy conservation, the rover continued remote science activities during the three-sol window. Instruments including ChemCam and the Remote Micro-Imager captured data on geological targets named Titicaca, Pampas, and Salta. The team also performed dust devil studies and Mastcam tau observations to monitor the Martian atmosphere and surface conditions. ## Testing Parallelism for Efficiency On sol 5061, engineers executed a new test to evaluate the feasibility of running multiple tasks simultaneously. By performing the CheMin data transfer while simultaneously transmitting data to an orbiter, the team aims to reduce the total time the rover remains awake, thereby saving critical power as the mission’s energy output gradually declines. ## Instrumental Data Processing The CheMin instrument, which analyzes mineralogy, requires high CPU usage to transfer science data to the rover’s flight computers. The recent test paired this high-demand activity with a communication downlink window. While initial observations suggest the test was successful, the engineering team is currently analyzing the telemetry to confirm the safety and efficiency. ## Mission Longevity Strategies As Curiosity ages, the mission team must continuously adapt operational strategies to account for decreasing power availability. Parallelism represents a key technical shift in how the rover manages its daily schedule. By optimizing the execution of concurrent tasks, NASA extends the operational lifespan of the rover’s hardware and maximizes its scientific output. ## Geological Context of Nazca The Nazca campaign focuses on analyzing crystal formations and layered bedrock in the vicinity. These geological features provide essential insights into the history of Mars. By characterizing the drill tailings and performing multiple instrument analyses, scientists hope to better understand the environmental conditions that shaped this specific region of the Martian surface. ## Future Operational Outlook Following the completion of the recharging sols, the rover will return to its standard drilling and cleanup activities. The team remains focused on wrapping up the Nazca campaign while maintaining the rover’s health. Future updates will detail the results of the RAGE procedure and the final analysis of the collected geological samples. ## Sources covering this story - https://science.nasa.gov/blog/curiosity-blog-sols-5056-5062-charging-back-up/ — --- _Summary written by Brifing from the original reporting.
