Fluorite veins in Jezero Crater reveal ancient Martian hydrothermal systems
The Perseverance rover has identified evidence of ancient hydrothermal activity in Mars' Jezero Crater, suggesting that hot water once circulated beneath the planet's surface. Analysis of the Margin Unit-a region previously thought to be a simple lake shoreline-revealed that minerals were altered in at least three distinct stages, leaving behind calcium sulfate and fluorite veins. This discovery shifts the understanding of Martian geology from a…
NASA's Perseverance rover has found evidence that water has interacted with rocks in Jezero Crater on Mars multiple times, including a period when hot underground waters circulated beneath the planet's ancient surface. The discovery comes from an area near the rim of Jezero Crater, known as the Margin Unit, which Perseverance has been exploring since 2023. The rover's observations show that at least three different episodes of water interacting …
NASA Discovery: Perseverance rover reveals complex water systems...
When NASA's Perseverance rover reached the inner edge of Mars' Jezero Crater in September 2023, mission scientists were surprised by what they found. Called the "Margin Unit," the geologic area stretches along the shoreline of an ancient Martian lake, so they expected sedimentary rocks, which would have formed as layers of sand piled on top of each other over millennia. Composed of clay and silt, sedimentary rocks on Earth are good at preserving…
