Today in History: Life on Mars?

On this day (June Twenty-Eight) in 1911 a meteorite fell to earth in Abu Hummus, Egypt. It was the first meteorite to show that water once existed on Mars. It is also suggestive, but not conclusive, that bacteria once existed on Mars. That’s all really cool, but stop and think about it for a moment. Scientists can actually tell that the rock originated on a specific planet in our solar system. That just blows my mind.
