NASA find signs of liquid water on Mars' surface

NASA scientists announced a breaking discovery today; that flowing water has been found on the surface of Mars, ending decades of speculation that the red planet could indeed be home to not only water, but potentially life.
Earlier today, NASA and the Nature Geoscience journal released findings which state that the long dark streaks found on the surface of Mars represent a sign of flowing water across the planets surface.
The dark streaks in question – which were discovered in 2010 – span between 5 metres wide and 100 metres long. In recent years, scientists have worked towards identifying their light signature, and have now publicly concluded that the streaks contain mineral salts that absorb moisture.

The question which remains is, ultimately, where would flowing water originate from? A likely theory, presented by astrologists, is that water across the surface of Mars might originate from underground water contained in ice or salty aquifers, or that water condenses into liquid from Mars’ atmosphere.
While it has been known for years now that Mars does hold reserves of frozen water in its poles, and that the planet likely possessed oceans billions of years ago, NASA’s latest discovery transforms out understanding of the planet; indicating that Mars isn’t a barren world, but rather that it is still alive.
