There could be salt water runnin’ in them thar Martian hills! At least that’s how NASA’s news Monday of new evidence of the potential presence of flowing salt water sounded to my ears here in the southern Rockies.
The above photo from NASA’s spacecraft orbiting Mars is a picture of dark markings that scientists say suggest seasonal flows down a slope, overlaid with colors from a mineral-mapping spectrometer observing the same region. NASA says the dark, fingerlike markings advance down some slopes when temperatures rise.
One suggested explanation for the phenomenon is that salty water containing “an iron-mineral antifreeze,” like ferric sulfate, could flow seasonally on parts of Mars.
