NASA's Curiosity rover has developed large holes and cracks in its wheels after more than 14 years of traversing the Martian surface [1].
The degradation of the rover's mobility system highlights the extreme physical toll of long-term planetary exploration. As the vehicle continues its mission, the integrity of its wheels determines how much more of the Martian landscape can be safely explored.
Images released on July 24, 2026, show extensive damage to the rover's wheels [3]. These photos, beamed back from the surface of Mars, reveal large cracks and missing segments [3]. Some of the holes in the wheel rims are approximately several centimeters across [2].
The damage is concentrated in the rover's aluminum wheels, which have been exposed to the harsh, rocky terrain of Mars since 2012 [1, 4]. The rover has recently been operating in the Valle Grande region, where the abrasive environment continues to wear down the hardware [2].
"NASA's Curiosity rover has picked up some battle scars during its 14 years of exploring Mars, with giant holes in its wheels," NASA said [1].
While Curiosity continues to function, the wear and tear are significant. The rover's wheels were designed to withstand the environment, but the prolonged exposure to sharp rocks and extreme temperature swings has caused the metal to fatigue and puncture [1, 4].
This wear is a known risk for long-duration missions. Engineers monitor the wheels closely to adjust the rover's path and avoid terrain that could cause further structural failure. The current damage serves as a visual record of the challenges faced by robotic explorers on the Red Planet [1].

The physical degradation of Curiosity's wheels provides critical data for future Mars missions. By analyzing how aluminum fails under Martian conditions over a 14-year period, NASA can develop more resilient materials and wheel designs for the next generation of rovers, ensuring they can survive longer and travel further across abrasive terrains.
