Perseverance is the farthest-driving Mars rover on record. On Oct. 11, 2026, it reached 28.10 miles (45.22 kilometers), narrowly surpassing Opportunity’s final total of 28.06 miles (45.16 kilometers). Curiosity had driven more than 23.65 miles (38.07 kilometers) by that same date. These are cumulative rover odometer totals, not straight-line distances across Mars.
Sojourner, Spirit and Opportunity have completed their missions, so their totals are final. Curiosity and Perseverance were still active on the date of the latest NASA/JPL comparison, making their numbers dated snapshots. The distinction matters when asking which Mars rover has driven the farthest: Perseverance led on Oct. 11, but the active rovers’ totals can continue to change.
How far has each Mars rover driven?
NASA and the Jet Propulsion Laboratory (JPL) report five well-known Mars rovers’ driving totals. The figures mix completed-mission totals with dated readings for rovers still operating, so the status and date matter as much as the number.
| Rover | Reported driving distance | Status and context |
|---|---|---|
| Sojourner | About 330 feet (100 meters) | Completed its 83-sol mission in 1997. NASA/JPL figure reported in 2026. |
| Spirit | 4.8 miles (7.7 kilometers) | Completed mission; NASA’s current mission comparison reports the final distance. |
| Opportunity | 28.06 miles (45.16 kilometers) | Final odometry when NASA declared the mission complete on Feb. 13, 2019. |
| Curiosity | More than 23.65 miles (38.07 kilometers) | Active; NASA/JPL total as of Oct. 11, 2026. This is a dated snapshot and a lower bound, not an exact current odometer reading. |
| Perseverance | 28.10 miles (45.22 kilometers) | Active; NASA/JPL odometer reading on Oct. 11, 2026, when it took the record. |
The figures come from NASA/JPL’s Oct. 12, 2026 report of odometer readings through Oct. 11, NASA Science’s rover mission pages, and NASA’s dated announcement of Opportunity’s final odometry. Curiosity’s earlier total of nearly 18 miles (29 kilometers), reported by NASA in 2022, described its first ten years—not its current distance.

The table puts the gap between the generations in perspective. Sojourner’s roughly 100 meters is about one tenth of a kilometer; Spirit’s 7.7 kilometers is a substantial distance by comparison, but far below the totals reached by Opportunity, Curiosity and Perseverance. At the top, the two leading totals are nearly tied: Perseverance is ahead of Opportunity by only 0.04 mile, or roughly 64 meters. Curiosity’s reported lower bound is also already more than 23 miles, though the number published for it is not an exact odometer value.
Which rover holds the distance record?
Perseverance holds the record among Mars rovers as of Oct. 11, 2026. On its 2,006th Martian day, or sol, it completed a 91.31-meter (299.6-foot) drive and reached 28.10 miles (45.22 kilometers). Opportunity’s final odometry was 28.06 miles (45.16 kilometers), leaving Perseverance ahead by 0.04 mile—about 64 meters, or 210 feet.
That margin is small compared with either rover’s total. It is still enough to make Perseverance the new leader: the comparison is based on accumulated rover odometry, not a claim that it traveled farther in a straight line across the planet. The record is a comparison of measured driving totals, and the date attached to it identifies when Perseverance’s odometer passed Opportunity’s final figure.

NASA declared Opportunity’s mission complete on Feb. 13, 2019, and its final odometry was 28.06 miles (45.16 kilometers). That is why Opportunity’s number can be described as a final total, while Perseverance’s 28.10 miles is the reading recorded on a particular date during an active mission. The record describes the standing comparison at that point, not a guarantee that the number will remain unchanged as Perseverance drives on.
Why the totals need a date and a definition
Odometer distance is not a map-to-map distance
A rover’s cumulative driving distance adds up the distance it travels as it moves. It is not the straight-line span between its landing site and current position, the distance between Mars locations, or the length of one unusually long drive. A route that bends around terrain can accumulate more odometer distance than the rover’s net progress across the surface.
This distinction answers a common question about what “farthest-driving” means. The ranking here is based on how much each rover has driven in total, according to its odometry. It does not rank rovers by how far they ended up from their landing sites, how much ground lies between two points on a map, or how long one drive was. The 91.31-meter drive on Oct. 11, for example, was one part of Perseverance’s accumulated total; the 28.10-mile figure is the total reached after that drive.

Because the figures are cumulative, they also should not be confused with an average daily pace. A rover’s total grows as it drives, but its mission does not consist of a continuous journey at a uniform speed. NASA/JPL’s reported maximum one-sol capability for Perseverance—1,351 feet (412 meters)—is a capability figure, not a statement that the rover covers that distance every sol.
Active-mission totals keep changing
Perseverance and Curiosity were active when NASA/JPL reported the Oct. 11, 2026 figures. Treat their totals as readings from that date, not permanent final records. NASA/JPL gave Curiosity’s figure as “more than 23.65 miles (38.07 kilometers),” so greater precision is not established by that report. By contrast, Spirit and Opportunity have completed missions, and their reported totals are final.
The wording “more than” is important. It tells readers that Curiosity had exceeded the stated distance, but the published comparison does not provide an exact current total. Reporting it as exactly 23.65 miles would turn a lower bound into a precision the figure does not claim. The date matters for the same reason: Curiosity remained active, so a later odometer reading could be higher.
Do not substitute NASA’s 2022 report of nearly 18 miles (29 kilometers) for Curiosity’s later total. That report marked the rover’s first ten years and was accurate in that historical context. NASA/JPL’s Oct. 11, 2026 comparison gives the later figure of more than 23.65 miles (38.07 kilometers). The numbers refer to different reporting dates, rather than conflicting descriptions of the same moment.
How quickly did Perseverance set the record?
NASA/JPL says Perseverance accumulated its record distance in about five and a half years. Opportunity took almost 15 years to reach its final 28.06 miles (45.16 kilometers). The comparison shows that the newest record holder covered a similar total in much less elapsed time; it does not mean that either rover drove continuously or at a uniform rate.

Pick the symptom - the matching free tool is one click away.
Perseverance’s 91.31-meter (299.6-foot) drive on Oct. 11, 2026, was the drive that brought its cumulative total to the record figure. NASA/JPL also reports that the rover can cover as much as 1,351 feet (412 meters) in one sol. That is a stated maximum capability, not its average daily distance and not a typical distance for every sol.

The time comparison adds context but does not change the definition of the record. Perseverance reached a total slightly above Opportunity’s final distance in about five and a half years, while Opportunity’s nearly 15 years brought it to 28.06 miles. Those elapsed periods do not tell readers how many days each rover actually drove, nor do they establish a constant pace. The stated figures support the conclusion that Perseverance accumulated a comparable odometer distance in less time; they do not explain every operational factor behind the difference.
How autonomous navigation changed rover driving
One reason Perseverance can cover ground differently from earlier rovers is autonomous navigation, or AutoNav. NASA/JPL says Perseverance used AutoNav for more than 90% of its total distance. The first Martian AutoNav system, used on Opportunity and Spirit, was used for about 5% of their distance. These percentages refer to the share of distance driven with the system, not the share of mission time or the proportion of all driving decisions made without human involvement.
In other words, AutoNav is a useful comparison point for the driving technology, not a separate distance record. NASA/JPL reports that most of Perseverance’s accumulated distance was driven using AutoNav, while the first Martian system used on Spirit and Opportunity accounted for about 5% of their distance. Those percentages describe how much distance was covered with the system. They should not be recast as percentages of total mission time, or as a claim that every navigation decision during the remaining distance followed one particular process.

That matters on Mars because driving is not simply a matter of following a clear, familiar road. Perseverance operations deputy team chief Mark Maimone said: “The rover that broke this record did so by making its own decisions about the path. Given the autonomy to just go, Perseverance is a better driver than the one that landed, and we’re not done,” NASA/JPL reported on Oct. 12, 2026.
The milestone is therefore about both distance and driving technology. NASA/JPL project manager Steven Lee said: “It is an honor to be working on Perseverance at a moment when the technology has evolved to the point that drives like these are routine.” The statement describes the team’s view of the technology; the record itself remains the measured odometer total.
The quoted comments offer a team perspective on why the new total is notable: autonomy has changed how much of the rover’s route it can navigate on its own. They do not replace the numerical comparison. To identify the record holder, use the dated odometer figures; to explain a relevant difference in driving capability, include the AutoNav comparison and its precise scope.

What the record does—and does not—say
- It ranks accumulated driving distance. The record compares rover odometry, not scientific output, mission duration, or the total area explored.
- It is a close comparison at the top. Perseverance’s Oct. 11, 2026 reading exceeded Opportunity’s final total by about 64 meters (210 feet).
- It is a dated snapshot for active rovers. Curiosity and Perseverance can add distance after the reported date, while the completed-mission totals for Spirit and Opportunity do not change.
- It should not be read as a daily pace. Perseverance’s maximum reported one-sol capability is not an average, and elapsed time to a total does not imply uninterrupted driving.
- Distance alone does not measure mission value. A longer odometer total answers how far a rover drove, not what it discovered or how important its work was.
The figures can support several comparisons, but each answers a different question. Total odometer distance identifies the record holder. Final versus active status tells whether a figure can still change. Elapsed time gives a broad comparison of how quickly two rovers accumulated similar totals. AutoNav use adds context about driving technology. None of those measures, by itself, ranks scientific contributions or establishes which rover was “best” overall.

The comparison uses NASA/JPL’s “NASA’s Perseverance Sets Off-World Record for Total Distance Driven,” published Oct. 12, 2026, with figures through Oct. 11; NASA Science’s current Perseverance, Spirit and Opportunity mission pages; NASA Science’s Opportunity page for its final odometry and mission-completion date; and NASA’s Aug. 5, 2022 Curiosity update for the historical ten-year figure. The Oct. 11 figures for the active rovers are snapshots, not final mission totals.
For a concise answer, give the rover, odometer distance, and date or final-status label together. On Oct. 11, 2026, Perseverance had driven 28.10 miles (45.22 kilometers), the leading reported Mars-rover total. Opportunity’s final total was 28.06 miles (45.16 kilometers), and Curiosity had driven more than 23.65 miles (38.07 kilometers) by that date. Those labels preserve the distinction between a record-setting active rover, a completed former record holder, and another active rover whose reported number is a lower bound.

Are these distances straight-line measurements across Mars?
No. They are cumulative rover odometer totals—the distance driven along a rover’s route—not straight-line distances from a landing site, between two locations, or the length of one drive.
Why does Curiosity’s distance sometimes appear as nearly 18 miles?
NASA’s Aug. 5, 2022 report described nearly 18 miles (29 kilometers) as Curiosity’s total during its first ten years. NASA/JPL later reported more than 23.65 miles (38.07 kilometers) through Oct. 11, 2026.
How much farther is Perseverance’s record than Opportunity’s?
Perseverance’s Oct. 11, 2026 total is ahead by 0.04 mile, about 64 meters or 210 feet. It passed Opportunity after a 91.31-meter (299.6-foot) drive that day.
Does Perseverance drive 1,351 feet every sol?
No. NASA/JPL reports that Perseverance can cover as much as 1,351 feet (412 meters) in one sol. That is a maximum capability, not its average or a typical daily distance.
What does AutoNav have to do with the record?
NASA/JPL says Perseverance used autonomous navigation for more than 90% of its total distance. The first Martian AutoNav system, used on Opportunity and Spirit, was used for about 5% of their distance. These percentages describe distance driven with the system, not mission time.
The Bottom Line
As of Oct. 11, 2026, Perseverance leads the Mars-rover distance comparison at 28.10 miles (45.22 kilometers), just ahead of Opportunity’s final 28.06 miles (45.16 kilometers). Curiosity had driven more than 23.65 miles (38.07 kilometers) by that date. These are cumulative odometer totals; active-rover figures need dates, and distance alone does not measure scientific value.
