NASA’s Perseverance vehicle took a new photo of a rock on the Red Planet that looks very much like an avocado. Since landing on Mars on February 18, 2021, the rover has passed through the planet’s Jezero Crater to search for signs of ancient life. The robotic rover encountered some intriguing features of the Red Planet during its journey.

Among them is a pair of rocks that resemble a ripe avocado cut in half, photographed on September 8. One of the rounded halves is upside down in the foreground of the image, while the other half has a distinctive dimple in the middle. The rough surface of the stone even reflects the dimpled, leathery texture of the avocado skin.

The final photo was taken using Perseverance’s Mastcam-Z, which includes a pair of cameras mounted above the rover’s head-like mast. It was taken on the 907th Marian day, or sol, on the Red Planet. (A solar day is slightly longer than an Earth day; about 24 hours and 40 minutes.)

With the Ingenuity Mars helicopter serving as the rover’s spotter, Perseverance is exploring the 28-mile-wide (45 kilometers) Jesero Crater, which contained a large lake and river delta billions of years ago. The rover’s primary goals include characterizing the ancient environment and collecting samples to be sent to Earth on future missions.

This new rock find adds to the growing collection of funny-shaped rocks the rover has discovered. In August, the rover photographed a rock outcropping that resembled a shark’s fin and an accompanying rock that resembled a crab’s claw. In June, Perseverance also discovered a ring-shaped rock with a hole in the middle, which scientists believe may be the remains of a large asteroid that hit the Red Planet.

Such images are examples of a phenomenon known as pareidolia, which describes the human brain’s tendency to apply a familiar pattern to random visual data.
