NASA Mars Rovers: Side-by-Side Comparison
- NASA has released a side-by-side comparison of the distinct Martian environments currently being explored by the Curiosity and Perseverance rovers.
- Both rovers are car-sized vehicles tasked with studying surfaces that are billions of years old.
- The Curiosity rover, which is 15 years into its mission, is currently navigating younger terrain.
NASA has released a side-by-side comparison of the distinct Martian environments currently being explored by the Curiosity and Perseverance rovers. The agency showcased these differences through dueling panoramas created from hundreds of photographs captured between the end of 2025 and the beginning of 2026.
Both rovers are car-sized vehicles tasked with studying surfaces that are billions of years old. However, the specific geological regions they are traversing offer starkly different perspectives of the planet’s history.
Contrasting Geological Terrains
The Curiosity rover, which is 15 years into its mission, is currently navigating younger terrain. Its operations are centered in the foothills of a Martian mountain.

In contrast, the Perseverance rover is exploring a crater rim. According to NASA, this region contains some of the most ancient landscapes in the entire solar system.
By comparing the data and imagery from these two separate locations, NASA is able to visualize the diverse landscapes across the Martian surface and the varying ages of the terrain being studied by its robotic explorers.
