Billions of Years of Martian History—NASA’s Perseverance & Curiosity Rovers | JPL

NASA has two rovers on Mars—but they are exploring distinct eras of the planet’s past. Separated by 2,300 miles, the two rovers are uncovering clues from moments in Martian history. Perseverance is on the rim of Jezero Crater, where it is studying examples of the oldest Martian terrain explored while searching for signs of ancient microbial life. Meanwhile, Curiosity is climbing Mount Sharp inside Gale Crater, where layers of rock reveal how Mars’ climate changed as water dried up from its surface.

Together, the missions are helping scientists reconstruct how Mars formed, when and where water existed, and the planet’s history of having the right conditions to support life. Their discoveries are offering a clearer picture of how Mars became the dry and dusty world we know today.
