While the Rover is investigating rocks on Mars, scientists have discovered that a rock found in Morocco in 2001 came from Mars. The Rover is searching for water on Mars and this rock gives astronomers evidence that water once flowed there, since it's a magmatic rock, formed when water moved from the core of the planet to the surface.
David Whitehouse writes in bbcnews.com that the rock came from a bed of meteorites found in the Atlas mountains, and the location has been kept secret. "It is a remarkable experience to hold it in your hand," says Bruno Fectay, one of the people who found it. "When you hold it you are in a Martian magmatic chamber, deep in a volcano under the surface of Mars. We will never be able to go to such a place. This rock is our passport."
There are mysterious worlds to be discovered right here on Earth.
