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.

Endeavour Crater by the
Opportunity rover currently exploring Mars.
