NASA’s Perseverance Mars Rover Ready to Roll for Miles in Years Ahead

December 18, 2025

After nearly five years on Mars, NASA’s Perseverance rover has traveled almost 25 miles (40 kilometers), and the mission team has been busy testing the rover’s durability and gathering new science findings on the way to a new region nicknamed “Lac de Charmes,” where it will be searching for rocks to sample in the coming year.

Like its predecessor Curiosity, which has been exploring a different region of Mars since 2012, Perseverance was made for the long haul. NASA’s Jet Propulsion Laboratory in Southern California, which built Perseverance and leads the mission, has continued testing the rover’s parts here on Earth to make sure the six-wheeled scientist will be strong for years to come. This past summer, JPL certified that the rotary actuators that turn the rover’s wheels can perform optimally for at least another 37 miles (60 kilometers); comparable brake testing is underway as well.

Over the past two years, engineers have extensively evaluated nearly all the vehicle’s subsystems in this way, concluding that they can operate until at least 2031.

NASA’s Perseverance used its navigation cameras to capture its record-breaking drive of 1,350.7 feet (411.7 meters) on June 19, 2025. The navcam images were combined with rover data and placed into a 3D virtual environment, resulting in this reconstruction with virtual frames inserted about every 4 inches (0.1 meters) of drive progress.

“These tests show the rover is in excellent shape,” said Perseverance’s deputy project manager, Steve Lee of JPL, who presented the results on Wednesday at the American Geophysical Union’s annual meeting, the largest gathering of planetary scientists in the United States. “All the systems are fully capable of supporting a very long-term mission to extensively explore this fascinating region of Mars.”

Perseverance has been driving through Mars’ Jezero Crater, the site of an ancient lake and river system, where it has been collecting scientifically compelling rock core samples. In fact, in September, the team announced that a sample from a rock nicknamed “Cheyava Falls” contains a potential fingerprint of past microbial life.

More efficient roving

In addition to a hefty suite of six science instruments, Perseverance packs more autonomous capabilities than past rovers. A paper published recently in IEEE Transactions on Field Robotics highlights an autonomous planning tool called Enhanced Autonomous Navigation, or ENav. The software looks up to 50 feet (15 meters) ahead for potential hazards, then chooses a path without obstacles and tells Perseverance’s wheels how to steer there.

Engineers at JPL meticulously plan each day of the rover’s activities on Mars. But once the rover starts driving, it’s on its own and sometimes has to react to unexpected obstacles in the terrain. Past rovers could do this to some degree, but not if these obstacles were clustered near each other. They also couldn’t react as far in advance, resulting in the vehicles driving slower while approaching sand pits, rocks, and ledges. In contrast, ENav’s algorithm evaluates each rover wheel independently against the elevation of terrain, trade-offs between different routes, and “keep-in” or “keep-out” areas marked by human operators for the path ahead.

“More than 90% of Perseverance’s journey has relied on autonomous driving, making it possible to quickly collect a diverse range of samples,” said JPL autonomy researcher Hiro Ono, a paper lead author. “As humans go to the Moon and even Mars in the future, long-range autonomous driving will become more critical to exploring these worlds.”

New science

A paper published Wednesday in Science details what Perseverance discovered in the “Margin Unit,” a geologic area at the margin, or inner edge, of Jezero Crater. The rover collected three samples from that region. Scientists think these samples may be particularly useful for showing how ancient rocks from Mars’ deep interior interacted with water and the atmosphere, helping create conditions supportive for life.

From September 2023 to November 2024, Perseverance ascended 1,312 feet (400 meters) of the Margin Unit, studying rocks along the way — especially those containing the mineral olivine. Scientists use minerals as timekeepers because crystals within them can record details about the precise moment and conditions in which they formed.

Jezero Crater and the surrounding area holds large reserves of olivine, which forms at high temperatures, typically deep within a planet, and offers a snapshot of what was going on in the planet’s interior. Scientists think the Margin Unit’s olivine was made in an intrusion, a process where magma pushes into underground layers and cools into igneous rock. In this case, erosion later exposed that rock to the surface, where it could interact with water from the crater’s ancient lake and carbon dioxide, which was abundant in the planet’s early atmosphere.

Those interactions form new minerals called carbonates, which can preserve signs of past life, along with clues as to how Mars’ atmosphere changed over time.

“This combination of olivine and carbonate was a major factor in the choice to land at Jezero Crater,” said the new paper’s lead author, Perseverance science team member Ken Williford of Blue Marble Space Institute of Science in Seattle. “These minerals are powerful recorders of planetary evolution and the potential for life.”

Together, the olivine and carbonates record the interplay between rock, water, and atmosphere inside the crater, including how each changed over time. The Margin Unit’s olivine appeared to have been altered by water at the base of the unit, where it would have been submerged. But the higher Perseverance went, the more the olivine bore textures associated with magma chambers, like crystallization, and fewer signs of water alteration.

As Perseverance leaves the Margin Unit behind for Lac de Charmes, the team will have the chance to collect new olivine-rich samples and compare the differences between the two areas.

The center leverages AI along with JPL’s unique infrastructure, unrivaled tools, and years of operations expertise to support industry partners developing future planetary surface missions.

NASA’s Jet Propulsion Laboratory in Southern California on Wednesday inaugurated its Rover Operations Center (ROC), a center of excellence for current and future surface missions to the Moon and Mars. During the launch event, leaders from the commercial space and AI industries toured the facilities, participated in working sessions with JPL mission teams, and learned more about the first-ever use of generative AI by NASA’s Perseverance Mars rover team to create future routes for the robotic explorer.

The center was established to integrate and innovate across JPL’s planetary surface missions while simultaneously forging strategic partnerships with industry and academia to advance U.S. interests in the burgeoning space economy. The center builds on JPL’s 30-plus years of experience developing and operating Mars surface missions, including humanity’s only helicopter to fly at Mars as well as the only two active planetary surface missions.

“The Rover Operations Center is a force multiplier,” said JPL Director Dave Gallagher. “It integrates decades of specialized knowledge with powerful new tools, and exports that knowledge through partnerships to catalyze the next generation of Moon and Mars surface missions. As NASA’s federally funded research and development center, we are chartered to do exactly this type of work — to increase the cadence, the efficiency, and the impact for our transformative NASA missions and to support the commercial space market as they take their own giant leaps.”

Genesis of ROC

Through decades of successful Mars rover missions, JPL has continuously improved the unique autonomy, robotic capabilities, and best practices that have been demanded by increasingly complex robotic explorers. The ROC offers an accessible centralized structure to facilitate future exploration efforts.

“Our rovers are lasting longer and are more sophisticated than ever before. The scientific stakes are high, as we have just witnessed with the discovery of a potential biosignature in Jezero Crater by the Perseverance mission. We are starting down a decade of unprecedented civil and commercial exploration at the Moon, which will require robotic systems to assist astronauts and support lunar infrastructure,” said Matt Wallace, who heads JPL’s Exploration Systems Office. “Mobile vehicles like rovers, helicopters, and drones are the most dynamic and challenging assets we operate. It’s time to take our game up a notch and bring everybody we can with us.”

Future forward

A key focus of the ROC is on the more rapid infusion of higher-level autonomy into surface missions through partnerships with the AI and commercial space industries. The objective is to catalyze change to deliver next-generation science and exploration capabilities for the nation and NASA.

As NASA’s only federally funded research and development center, JPL has been evolving vehicle autonomy since the 1990s, when JPL began developing Sojourner, the first rover on another planet. Improvements to vehicle independence over the years have included the evolution of autonomy in sampling activities, driving, and science-target selection. Most recently, those improvements have extended to the development of Perseverance’s ability to autonomously schedule and execute many commanded energy-intensive activities, like keeping warm at night, as it sees fit. This capability allows the rover to conserve power, which it can reallocate in real time to perform more science or longer drives.

With the explosion of AI capabilities, the ROC rover team is leaving no Mars stone unturned in the hunt for future efficiencies.

“We had a small team complete a ‘three-week challenge,’ applying generative AI to a few of our operational use cases. During this challenge, it became clear there are many opportunities for AI infusion that can supercharge our capabilities,” said Jennifer Trosper, ROC program manager at JPL. “With these new partnerships, together we will infuse AI into operations to path-find the next generation of capabilities for science and exploration.”

Håvard Grip, chief pilot of NASA’s Mars Ingenuity Helicopter — the only aircraft to fly on another planet — offers insights into aerial exploration of the Red Planet at the lab’s 25-Foot Space Simulator, which subjects spacecraft to the harsh conditions of space.

During the ROC’s inauguration, attendees toured JPL operations facilities, including where the rover drivers plan their next routes. They also visited JPL’s historic Mars Yard, which reproduces Martian terrain to test rover capabilities, and the massive 25-Foot Space Simulator that has tested spacecraft from Voyagers 1 and 2 to Perseverance to America’s next generation of lunar landers. A panel discussion explored the historical value of rovers and aerial systems like the Ingenuity Mars Helicopter in planetary surface exploration. Also discussed was the promise of a new public-private partnership opportunity across a virtual network of operational missions.

Attendees were briefed on tiered engagement options for partners, from mission architecture support to autonomy integration, testing, and operations. These opportunities extend to science and human precursor robotic missions, as well as to human-robotic interaction and spacewalks for astronauts on the Moon and Mars.

A highlight for event participants came when the Perseverance team showcased how the ROC’s generative AI can assist rover planners in creating future routes for the rover. The AI analyzed high-resolution orbital images of Jezero Crater and other relevant data and then generated waypoints that kept Perseverance away from hazardous terrain.

Managed for NASA by Caltech, JPL is the home of the Rover Operations Center (ROC).

NASA Rover Detects Electric Sparks in Mars Dust Devils, Storms

December 4, 2025

Three Martian dust devils can be seen near the rim of Jezero Crater in this short video made of images taken by a navigation camera aboard NASA’s Perseverance rover on Sept. 6, 2025. The microphone on the rover’s SuperCam previously captured audio when a dust devil passed over.

Perseverance confirmed a long-suspected phenomenon in which electrical discharges and their associated shock waves can be born within Red Planet mini-twisters.

NASA’s Perseverance Mars rover has recorded the sounds of electrical discharges —sparks — and mini-sonic booms in dust devils on Mars. Long theorized, the phenomenon has now been confirmed through audio and electromagnetic recordings captured by the rover’s SuperCam microphone. The discovery, published Nov. 26 in the journal Nature, has implications for Martian atmospheric chemistry, climate, and habitability, and could help inform the design of future robotic and human missions to Mars.

A frequent occurrence on the Red Planet, dust devils form from rising and rotating columns of warm air. Air near the planet’s surface becomes heated by contact with the warmer ground and rises through the denser, cooler air above. As other air moves along the surface to take the place of the rising warmer air, it begins to rotate. When the incoming air rises into the column, it picks up speed like spinning ice skaters bringing their arms closer to their body. The air rushing in also picks up dust, and a dust devil is born.

SuperCam has recorded 55 distinct electrical events over the course of the mission, beginning on the mission’s 215thMartian day, or sol, in 2021. Sixteen have been recorded when dust devils passed directly over the rover.

Decades before Perseverance landed, scientists theorized that the friction generated by tiny dust grains swirling and rubbing against each other in Martian dust devils could generate enough of an electrical charge to eventually produce electrical arcs. Called the triboelectric effect, it’s the phenomenon at play when someone walks over a carpet in socks and then touches a metal doorknob, generating a spark. In fact, that is about the same level of discharge as what a Martian dust devil might produce.

“Triboelectric charging of sand and snow particles is well documented on Earth, particularly in desert regions, but it rarely results in actual electrical discharges,” said Baptiste Chide, a member of the Perseverance science team and a planetary scientist at L’Institut de Recherche en Astrophysique et Planétologie in France. “On Mars, the thin atmosphere makes the phenomenon far more likely, as the amount of charge required to generate sparks is much lower than what is required in Earth’s near-surface atmosphere.”

Perseverance’s SuperCam instrument carries a microphone to analyze the sounds of the instrument’s laser when it zaps rocks, but the team has also captured the sounds of wind and even the first audio recording of a Martian dust devil. Scientists knew it could pick up electromagnetic disturbance (static) and sounds of electrical discharges in the atmosphere. What they didn’t know was if such events happened frequently enough, or if the rover would ever be close enough, to record one. Then they began to assess data amassed over the mission, and it didn’t take long to find the telltale sounds of electrical activity.

The SuperCam microphone on NASA’s Perseverance captured this recording of the sounds of electrical discharge as a dust devil passed over the Mars rover on Oct. 12, 2024. The three crackles can be heard in between the sounds of the dust devil’s front and trailing walls.

Crackle, pop

“We got some good ones where you can clearly hear the ‘snap’ sound of the spark,” said coauthor Ralph Lorenz, a Perseverance scientist at the Johns Hopkins Applied Physics Lab in Laurel, Maryland. “In the Sol 215 dust devil recording, you can hear not only the electrical sound, but also the wall of the dust devil moving over the rover. And in the Sol 1,296 dust devil, you hear all that plus some of the particles impacting the microphone.”

Thirty-five other discharges were associated with the passage of convective fronts during regional dust storms. These fronts feature intense turbulence that favor triboelectric charging and charge separation, which occurs when two objects touch, transfer electrons, and separate — the part of the triboelectric effect that results in a spark of static electricity.

Researchers found electrical discharges did not seem to increase during the seasons when dust storms, which globally increase the presence of atmospheric dust, are more common on Mars. This result suggests that electrical buildup is more closely tied to the localized, turbulent lifting of sand and dust rather than high dust density alone.

While exploring the rim of Jezero Crater on Mars, NASA’s Perseverance rover captured new images of multiple dust devils in January 2025. These captivating phenomena have been documented for decades by the agency’s Red Planet robotic explorers.

Profound effects

The proof of these electrical discharges is a discovery that dramatically changes our understanding of Mars. Their presence means that the Martian atmosphere can become sufficiently charged to activate chemical reactions, leading to the creation of highly oxidizing compounds, such as chlorates and perchlorates. These strong substances can effectively destroy organic molecules (which constitute some of the components of life) on the surface and break down many atmospheric compounds, completely altering the overall chemical balance of the Martian atmosphere.

This discovery could also explain the puzzling ability of Martian methane to vanish rapidly, offering a crucial piece of the puzzle for understanding the constraints life may have faced and, therefore, the planet’s potential to be habitable.

Given the omnipresence of dust on Mars, the presence of electrical charges generated by particles rubbing together would seem likely to influence dust transport on Mars as well. How dust travels on Mars plays a central role in the planet’s climate but remains poorly understood.

Confirming the presence of electrostatic discharges will also help NASA understand potential risks to the electronic equipment of current robotic missions. That no adverse electrostatic discharge effects have been reported in several decades of Mars surface operations may attest to careful spacecraft grounding practices. The findings could also inform safety measures developed for future astronauts exploring the Red Planet.
