A Mysterious Zebra Rock Has Been Spotted On Mars, Marking A One-Of-A-Kind Find On The Red Planet

A mysterious “zebra rock” has been spotted on Mars, and researchers have never seen anything like it before on the Red Planet, making it a one-of-a-kind find. NASA’s Perseverance rover captured images of the black-and-white striped rock on Mars’ Jezero crater.
On September 13, scientists acquired the images after the spacecraft had already left the area. The rock was named “Freya Castle” after a landmark in the United States’ Grand Canyon. It has a strange texture and stands out on the dusty, red landscape.
“Our knowledge of its chemical composition is limited, but early interpretations are that igneous and/or metamorphic processes could have created its stripes,” stated NASA representatives.
Igneous processes are associated with the crystallization and solidification of magma, while metamorphic processes refer to compositional changes in rocks due to high pressure and heat.
It makes sense because Mars was a volcanically active planet for millions of years, which could have provided the right environment for the rock to form.
The zebra rock is approximately eight inches across. The lighter-colored minerals might be feldspar, while the darker-colored minerals could be pyroxene or amphibole.
It is different from the bedrock on Mars, indicating that it came from somewhere else. One theory about the rock’s origin is that it rolled down from a spot higher up in the Jezero crater.
“This possibility has us excited,” said NASA representatives. “We hope that as we continue to drive uphill, Perseverance will encounter an outcrop of this new rock type so that more detailed measurements can be acquired.”
Currently, Perseverance is making its way up the steep slopes of the crater, marking the start of its fifth campaign called the Crater Rim Campaign. Scientists believe a river once emptied into a body of water at the crater. The rover is searching for signs of ancient life that might provide some hints about early Martian history.

So far, Perseverance has finished four campaigns on Mars. It first reached the crater in February 2021.
The journey to the top—the crater’s rim, which stretches about 1,000 feet above the basin floor—has been slow, but a lot more progress was made after the rover reached a flatter expanse of land.
“As we start the Crater Rim Campaign, our rover is in excellent condition, and the team is raring to see what’s on the roof of this place,” said Art Thompson, the Perseverance project manager at NASA’s Jet Propulsion Laboratory in Southern California.
Freya Castle is not the only interesting rock from the Jezero crater. In June, Perseverance captured images of an oddly light-colored boulder near the crater’s Mount Washburn.
In July, NASA saw photographs of a leopard-spotted rock. These recent rock discoveries show that Mars is more geologically diverse than previously thought.
