Light Shed on Wet Ancient Mars

High-Silica 'Halos' Shed Light on Wet Ancient Mars

Quote

Pale "halos" around fractures in bedrock analyzed by NASA's Curiosity Mars rover contain copious silica, indicating that ancient Mars had liquid water for a long time.

"The concentration of silica is very high at the centerlines of these halos," said Jens Frydenvang, a rover-team scientist at Los Alamos National Laboratory in New Mexico, and the University of Copenhagen in Denmark. "What we’re seeing is that silica appears to have migrated between very old sedimentary bedrock and into younger overlying rocks."

It's very encouraging to know that drinking water was once present on the surface of Mars, raises the possibility that some form of life may once have existed their, provided that the right conditions persisted for long enough

And what spectacular news it would be for mankind, once they possibly discover some kind of life form that once existed on wet Mars.

It will certainly be time then to 'pop' the champers.....

Even if there is no life on mars doesn't mean that left untouched there never will be.  

Never be tempted to open the oven before the scones are cooked.B)

There is no doubt a universal plan for mars that doesn't involve mankind.

A universal plan?

It'd be reassuring to discover that there is a universal plan, that there is a purpose to it all, that it's not all happening because of an energy spontaneously exploded into existence before gradually populating the universe with stars and over matter, and that it wasn't an incredible series of co-incidences that got the right elements in the right proportions to make the compounds thats mingled in the right way to form living cells!

True. It's a long shot to presume that the eternity before the universe happened up till the present day was constructed solely that life exist only here on Earth.

But who knows the true scale of things?

Our universe has provided the right measures at just the right time that we may live. It doesn't get much better than that. 

Look out there, it's all for us!

700.000 years is a quite short time considering that it took about 2.9 billion years for life on Earth to go from single-cellular to multi-cellular.

Actually, that headline is off by a factor of a thousand. As the body of the article, which agrees with other sources, says, the lake appears to have persisted between 3.8 and 3.1 billion years ago. That amounts to 700 million years, not 700 thousand.

I don't know guys, but if  Mars  did support life, where are all the fossils? Unless when Mars that had the biggest volcano   in our  galaxy  might have blown and  buried them all.

Suppose there was life on Mars for 700 million years total. There probably wouldn't have been time for it to evolve beyond single-cells.  This process took longer than that on Earth.  The Rover at Gale crater has a low power magnifying lens for its camera, but not a microscope. They could very easily miss minute fossils.  Perhaps at some point they'll get lucky and find  microorganisms in a colony, like the ancient stromatolites found on Earth. That probably would be visible to Curiosity.

Perhaps Martian life never reached a stage where hard, calcified body parts developed that could fossilize?

Even very early, primitive organisms, like bacteria, could leave fossils behind. For example-- cyanobacteria colonies (bacterial mats) secreted lime, which trapped other mineral. These left behind mounds known as stromatolites.

So the whole fossil record that shows the evolution of life on Earth is faked ?

No one can pinpoint exactly where when or how life began. 

Latest theories suggest at a certain point in history conditions were right for some sort of spontaneous genesis to occur in thermally heated shallow pools of mineral water, previously the idea of deep sea vents was favored by scientists and possibly still is.

For all we know life may have spawned in the rich soup of atmospheric gases before touching down.

Perhaps the first life was airborne?
