Perseverance is currently investigating inside Jezero Crater on Mars, and has been climbing the slope leading to the crater's rim since around August 2024. A photo taken just before the discovery of the rock in question shows that there are rocks of various sizes scattered around the crater.



The rocks discovered are shown below. This photo was taken by a NASA researcher who found a 'rock that hints at an unusual texture' from a photo taken with a low-resolution camera and re-photographed it with a high-resolution Mastcam-Z camera. The rock has been named 'Freya Castle'.



Below is a cropped image of the rock with the color tones adjusted. The entire rock has black and white stripes. According to NASA, this rock shows a texture that has not been found on Mars before. The NASA research team has made the initial guess that 'the stripes are thought to have been generated by

igneous or metamorphic processes,' and 'because the texture is different from the ground, it is thought to have rolled down from a high place.'



In addition, NASA conducted a popularity vote for the photos taken by Perseverance, and the photo of Freya Castle received many votes and was selected as 'Picture of the Week'. The past 'Picture of the Week' can be viewed at the following link.
