NASA’s Perseverance rover has uncovered iron-rich minerals in Jezero Crater rocks that on Earth often link to microbial activity. The discovery suggests Mars’ lake basin may have been more hospitable than thought. Still, scientists caution that only Earth-based analysis can confirm whether these are true biosignatures.NASA’s Perseverance rover has uncovered iron-rich minerals in Jezero Crater rocks that on Earth often link to microbial activity.
