Martian Meteorite Encountered Water on Mars

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 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.
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 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.
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 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.
Mars meteorite: contact with liquid water only 742 million years ago
A rock carved out of Mars 11 million years ago contains traces of liquid water. This has measurably changed its composition.
Unlocking Mars' History: The Dating of Water-Rock Interaction in the Lafayette Meteorite
