NASA’s two Mars Rovers have found some spectacular meteorites. On Earth, the only humans who are as successful at finding meteorites are professional meteorite hunters. Are meteorites that abundant on Mars or are these Rovers simply lucky? The answer to this question has a lot to do with the environment of the two planets. The surface of Earth has an environment that is rich in oxygen and moisture - both of which are rapidly destructive to iron meteorites. A meteorite that lands on Earth’s surface would rust away in a blink of geologic time. Mars, however, has very little oxygen and moisture in its atmosphere and surface soils. Meteorites that land on Mars can remain in excellent condition for millions - or even billions - of years. Mars is the perfect place to hunt for meteorites.
