GoKawiilMars Meteorite Found in Mali Reveals Billion-Year-Old Water Traces
Scientists analyzing a nearly two-pound meteorite discovered in Mali in 2022, now largely housed at a Maine museum, have determined it originated from Mars and contains zircon crystals dating back 4.1 billion years. A paper published in Science, led by NASA JPL's Yang Liu, describes the rock as showing evidence of magma cooling followed by alteration from subsurface water, making it one of only three known Mars meteorites this old.
GoKawiil's interpretation of the reporting above, not reported fact.
The meteorite's age and mineral composition could give researchers a rare, detailed timeline of how Mars's crust formed and how water interacted with it billions of years ago. One reviewer's comparison of the sample to a 'Rosetta Stone for Mars' suggests it may help scientists decode broader questions about the planet's early climate and the loss of its atmosphere and water over time.
- A nearly two-pound Mars meteorite found in Mali in 2022 is now confirmed as one of the oldest known samples from Mars.
- Zircon crystals in the rock date to 4.1 billion years ago, placing it among only three Mars meteorites of that age.
- Researchers say its mineral record may reveal how Mars's crust formed and how water once interacted with its surface.
