A meteorite discovered in a drawer at a university in 1931 harbors evidence of liquid water on Mars 742 million years ago, new research suggests.
The Lafayette meteorite is a glassy chunk of space rock about 2 inches (5 centimeters) long. It was found at Purdue University nearly a century ago, and no one knew who discovered it or where it came from. It wasn't until the 1980s that researchers discovered that the gasses trapped inside the mysterious rock matched the Martian atmosphere as measured by NASA's Viking landers, according to Purdue University.
