Perseverance Radar Points to a 4.2-Billion-Year-Old Delta in Jezero Crater, Extending the Timeline for Martian Habitability
To the point
Led by astrobiologist Emily Cardarelli, researchers used Perseverance's ground-penetrating radar to map a buried river delta in Jezero crater, revealing an ancient, long-lived water system dating to about 4.2 billion years ago and suggesting Mars could have supported habitable conditions and preserved biosignatures there.
