Mars, Meteorite

Tiny Mars Meteorite Unlocks Secrets of the Red Planet’s Past
A small, unassuming meteorite measuring just 10 centimeters is shedding light on the history of Mars. Discovered in 1931 in an old drawer at Purdue University, the rock is now the focus of a study revealing key details about the presence of water on our neighboring planet.
Mars meteorite found in drawer reveals history of water on Red Planet
"We think the water came from the melting of nearby sub-surface ice called permafrost, and that the permafrost melting was caused by magmatic activity that still occurs periodically on Mars to the present day.
Meteorite found in a drawer in 1929 contains ancient evidence of liquid water on Mars
A sliver of Martian rock that once lay hidden in a university drawer has helped researchers better understand the Red Planet’s geological history. Using isotopic dating, a team at Purdue University has determined that the “Lafayette Meteorite” likely interacted with liquid water approximately 742 million years ago.
Martian Meteorite Encountered Water on Mars: Scientists
Researchers from Purdue University have confirmed the so-called Lafayette Meteorite encountered Water before it left Mars behind. The unlikely journey that brought the Lafayette Meteorite to Purdue University’s Department of Earth,
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,
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 that time in history. Rather, they suspect the water came from permafrost melt, perhaps caused by molten rock moving through the planet's crust. The study appears in the Geochemical Perspectives Letters.
Meteorite found in a drawer at university contains 700-million-year-old evidence of water on Mars
The Lafayette meteorite was discovered in a drawer at Purdue University in 1931, with no clear indication of how it got there. A new analysis of the rock reveals evidence of liquid water on Mars 742 million years ago.
Meteorite that struck Mars reveals when the planet had liquid water
The study identified when water interacted with the meteorite and established that the dating was unaffected by events after it left Mars.
Bigger than the dinosaur-killer, asteroid S2 smashed life on Earth into a higher gear
Researchers discovered a 3.26-billion-year-old asteroid impact acted as 'giant fertilizer bomb,' aiding early microbial life.
