Mars rover unveils 'Freya Castle': a geological marvel
NASA reports another fascinating discovery made by the Perseverance rover on Mars. In Jezero Crater, the device has found a stone with an attention-grabbing appearance. Scientists are convinced that this is one of the most interesting finds encountered so far on the Red Planet.

The Perseverance rover captured an image of the stone with a unique, zebra-like pattern on September 13, 2023. The object, dubbed "Freya Castle," is about 20 centimetres wide, which corresponds to the length of an average adult male's hand, reports Science Alert. The unique pattern of light and dark stripes on this boulder stands out against other geological formations studied to date on Mars.

Perseverance used its Mastcam-Z camera suite to take multispectral images of the stone. With these images, scientists were able to develop hypotheses about the origin of this extraordinary cosmic object. "Our knowledge of Freya Castle's chemical composition is limited, but early interpretations suggest that its characteristic bands could have formed as a result of magmatic or metamorphic processes," wrote Athanasios Klidaras, a scientist from Purdue University, on NASA’s blog.
The Freya Castle stone is not attached to the ground, which may indicate that it comes from elsewhere. According to the scientists' theory, it might have rolled down from a higher part of the slope. The prospect of discovering similar formations during the rover's further climbing is extremely exciting for researchers. "We hope that during Perseverance’s further journey, it encounters a larger rock of this type so that we can take more detailed measurements," emphasizes Klidaras.
Freya Castle is not the only remarkable discovery made during Mars missions. This year, the Curiosity rover uncovered pure hydrogen sulfide in the Gale Crater, and another find, the Chevaya Falls rock, was covered in spots resembling animal patterns, which could suggest biological processes. Despite ruling out the involvement of organisms in the formation of these structures, these discoveries continue to attract scientists' attention.
the Perseverance rover on Mars
Since 2021, the Perseverance rover has been exploring the Red Planet in search of traces of ancient life. Its mission is part of NASA's Mars 2020 project. Perseverance landed in Jezero Crater, which was once filled with water and could have been an ideal environment for microbial life. The rover collects rock samples, which will await future missions to transport them to Earth.
The Mars Sample Return mission, jointly conducted by NASA and ESA, plans to launch a container with samples from the surface of Mars and safely deliver them to Earth. This is likely to occur in the early 2030s. It is also worth noting that the Perseverance mission focuses not only on Jezero Crater. Currently, the rover is exploring the Bright Angel area, where there is a unique type of rock named "popcorn rock." Scientists hope that this region will provide more information about Mars's history and its potential biological resources.
