Early Mars May Have Been A Lot Like Early Earth
A new study published in Nature Geoscience says it has found evidence that the early crust of Mars may have been much like that of ancient Earth.By Jake Godin | July 15, 2015

Using rock data gathered by Curiosity, a recent study published in Nature Geoscience found that many of the rocks in the crater had similar chemical makeup to ones found in Earth's crust.
The crust of a planet is its outermost layer — what you're standing on now. The rock on land, or the continental crust, is typically lighter than what you'd find deeper in the oceans, or the oceanic crust.
