Mars, Lafayette Meteorite

Meteorite found in an old desk shows Mars had water about 700 million years ago
The study identified when water interacted with the meteorite and established that the dating was unaffected by events after it left Mars.
Meteorite contains evidence of liquid water on Mars 742 million years ago
An asteroid struck Mars 11 million years ago and sent pieces of the red planet hurtling through space. One of these chunks of Mars eventually crashed into the Earth somewhere near Purdue University and is one of the few meteorites that can be traced directly to Mars.
How a Martian Meteorite Found in a Drawer Rewrites Mars’ Water History
Scientists have traced the origins of the Lafayette Meteorite back to Mars, dating its water-altered minerals to 742 million years ago. The findings suggest that the meteorite's interaction with water came from melting subsurface permafrost rather than surface water,
Ancient meteorite reveals evidence of liquid water on Mars 742 million years ago
A team of scientists has found evidence of liquid water on Mars from 742 million years ago in a Martian meteorite known as the Lafayette Meteorite. This meteorite, now at Purdue University, traveled from Mars to Earth after an asteroid impact on Mars about 11 million years ago sent fragments of the red planet into
4.45 billion-year-old mineral reveals hot water activity on Mars
Scientists analyzing the 'Black Beauty' meteorite have discovered a zircon grain that hints at hydrothermal systems on early Mars.
Meteorite crystals show evidence of hot water on ancient Mars
A rock that formed around 4.5 billion years ago on Mars before being blasted into space by a meteor strike and making its way to Earth contains telltale evidence that it was formed in the presence of
Oldest direct evidence of hot water activity on Mars found
New Curtin University-led research has uncovered what may be the oldest direct evidence of ancient hot water activity on Mars, revealing the planet may have been habitable at some point in its past.
Ancient hot water on Mars points to habitable past
New research has uncovered what may be the oldest direct evidence of ancient hot water activity on Mars, revealing the planet may have been habitable at some point in its past.
Discovery: Ancient Mars had hot water that could have supported life
Curtin University scientists discover 4.45-billion-year-old evidence of water activity on Mars, hinting at early habitability.
Rock once forgotten in a drawer plays key part in dating water on Mars
Despite the team's success in dating the water-rock interaction, the researchers don't think Mars was teeming with water at ...
