Explanation: What could create this unusual vein of rock on Mars? A leading hypothesis is that this thin rock layer dubbed "Homestake" was deposited by a running liquid -- like most mineral veins are here on Earth. And the running liquid of choice is water. Therefore, this mineral streak -- rich in calcium and sulfur -- is the latest in the growing body of evidence that part of Mars had a watery past. This, in turn, increases the speculation that Mars was once hospitable to life. Pictured above is a vista taken near the western rim of Endeavour Crater by the Opportunity rover currently exploring Mars. The inset image shows a close up of the recently discovered mineral vein.

Neat!
We’re already mining on Mars? That explains a lot.
Why couldn’t a giant, with a big hoe, do that?
They shouldn’t assume water does everything.
It's mine. Mars is my planet!

@semajretrac040 Mars gravity is 38% of Earth's. As I near Mars, I'll definitely feel the pull, but I'll weigh less there than on Earth.
