AI summary: The Perseverance rover’s SHERLOC instrument has identified potential organic material in rock samples from Mars’ Jezero crater. The findings suggest the presence of different organic chemicals associated with various salts, indicating multiple synthesis methods or distinct preservation conditions. The level of organic material appears to have changed over time, suggesting alterations in the production or deposition of these materials on Mars. While the specific chemicals remain unidentified, the data argues against the theory of these organics being delivered via meteorites. The results could provide insights into potential life on Mars.
