Mars Meteorite Reveals Evidence of Ancient Liquid Water

Scientists have dated minerals in the Lafayette Meteorite, confirming liquid water existed on Mars 742 million years ago.

  • The Lafayette Meteorite, traced directly to Mars, was discovered in a drawer at Purdue University in 1931.
  • Recent isotopic analysis shows the meteorite interacted with liquid water on Mars approximately 742 million years ago.
  • Researchers believe the water originated from melting subsurface ice, likely caused by magmatic activity.
  • The study confirms that the meteorite's age was not affected by its journey through space or entry into Earth's atmosphere.
  • This discovery provides a more precise timeline for water presence on Mars, enhancing our understanding of the planet's geological history.
