NASA Rover Uncovers 3.7-Billion-Year-Old River Delta Beneath Mars Surface
•NASA's Perseverance rover detected a 3.7-billion-year-old ancient river delta beneath Mars' Jezero Crater using ground-penetrating radar.
•The rover's RIMFAX instrument revealed layered sediments and eroded surfaces up to 115 feet (35 meters) underground, indicating a delta environment.
•This discovery provides some of the oldest evidence of water flow on Mars, predating the Western Delta and suggesting an early water-rich environment.
•The findings, published in Science Advances, highlight Jezero Crater's potential for biosignature preservation due to its ancient water history.
•The presence of ancient deltas on Mars is crucial for understanding the planet's past habitability and the possibility of microbial life.
