NASA’s Perseverance rover, using the RIMFAX ground-penetrating radar, uncovered buried, ancient river delta deposits beneath Jezero Crater dating to about 3.7–4.2 billion years ago—one of the oldest indicators of past liquid water on Mars and a crucial clue to the planet’s early habitability.
NASA’s Perseverance rover’s ground-penetrating radar detects what appears to be an ancient subsurface river delta buried beneath Jezero Crater’s Margin unit, dating to the Noachian era. The deep, layered clinoforms suggest long-lived aqueous conditions and potential habitats for past life, though alternative volcanic or shoreline explanations are also considered. This finding broadens Jezero’s known watery history, with more data from Perseverance yet to come.
NASA’s Perseverance rover, using the RIMFAX ground-penetrating radar, uncovered a much deeper, older delta beneath Jezero Crater, suggesting Mars had flowing surface water long before the present delta and extending the window for past habitability and potential biosignatures in the subsurface.
