Liquid water flows on today’s Mars, NASA confirms

RATE THIS! +53
Posted in Science on 28th Sep, 2015 11:09 PM by AlexMuller

New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present day Mars, NASA announced today. The flow of liquid water on Mars increaces the prospects of finding that life exists, or once existed, on the planet.

 
Researchers detected darkish signatures of hydrated minerals on slopes in several locations that appear to ebb and flow over time, based on spectrometer data. The signatures darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons.
 
“This is a significant development, as it appears to confirm that water, albeit briny, is flowing today on the surface of Mars,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington.
 
“We found the hydrated salts only when the seasonal features were widest, which suggests that either the dark streaks themselves or a process that forms them is the source of the hydration.
 
In either case, the detection of hydrated salts on these slopes means that water plays a vital role in the formation of these streaks,” said Lujendra Ojha of the Georgia Institute of Technology in Atlanta, lead author of a report on these findings published Sept. 28 by Nature Geoscience.
 
Ojha and his co-authors interpret the spectral signatures as caused by hydrated minerals called perchlorates. On Earth, naturally produced perchlorates are concentrated in deserts, and some types of perchlorates can be used as rocket propellant.

After so many speculations now we have some solid (or rather liquid) evidence at last! Yes, this increases chances that life could existed or exists on the red planet, very intriguing

However, water is just one of the requirements for life forms... Reply
