Lafayette Meteorite Reveals Mars Had Liquid Water
Researchers confirm the presence of liquid water on Mars through mineral analysis of a meteorite found in Indiana.
- The Lafayette Meteorite, discovered in a drawer at Purdue University, shows evidence of liquid water on Mars 742 million years ago.
- Scientists used argon isotopes to accurately date the minerals, which formed through interaction with water on Mars.
- Research suggests the water originated from melting permafrost due to magmatic activity rather than from abundant surface water.
- The meteorite is part of the rare nakhlite category, which includes only 32 known samples from Mars.
- The study provides a robust method for dating meteorites that can help understand the history of water on other planetary bodies.
