NASA is currently releasing news of evidence of water on, or near, the surface of Mars.

Dark streaks guide search for life on Mars

The story of water on Mars seems to be getting wetter, saltier and altogether more juicy.

NASA scientists have found evidence for liquid brines near the planet's surface that might provide a habitable zone for microbes today. If the discovery holds, it should guide future missions to Mars in the quest to find out whether the red planet can support life.

Images from the High Resolution Imaging Science Experiment (HiRISE), a camera aboard the Mars Reconnaissance Orbiter (MRO), have revealed thousands of narrow, dark streaks that appear on some of Mars's steep slopes during warmer seasons.

Water on Mars: Scientists find strongest evidence yet

For decades, space scientists have searched Mars for signs of water, the liquid generally believed to be essential for life. Now, they may well have found it.

Scientists announced Thursday that they had detected dozens of slopes across the southern hemisphere of the planet where previously undetected dark streaks come and go with the seasons. When the planet heats up, the streaks appear and expand downhill. When it gets cold, the streaks disappear.
...

It’s a discovery that, if confirmed, would fundamentally change our understanding of Mars and would strongly support the widely held theory that the planet was once far more wet and warm. And scientists say the discovery of water would provide our best target yet for finding possible life beyond Earth.

Finger-like features visible in images from Mars may be streams of salty water spilling over the rims of craters, scientists believe.

The puzzling clusters of dark lines fade in winter and reappear in the spring.

New hints of saltwater on Mars

Flows of saltwater may ooze from rocky outcrops on Mars. Seasonal dark streaks on some Martian slopes could come from briny water, American and Swiss researchers suggest in the Aug. 5 Science.

Still, the researchers haven’t actually detected any water, frozen or liquid. Nor can they explain how the water would be replenished in the dry, harsh Martian environment.

Mars: Nasa images show signs of flowing water
"This could be the first flowing water," said Professor McEwen. This has profound implications in the search for extraterrestrial life. "Liquid water is absolutely essential for life, and we've found life on Earth in pretty much every moist niche," said Dr Lewis Dartnell, astrobiologist at University College London, who was not involved in the study. "So perhaps there could be hardy microbes surviving in these short periods of summer meltwater on the desert surface of Mars."

This was echoed by an expert on life in extreme environments, Professor Shiladitya DasSarma of the University of Maryland, also not involved in this study: "Their results are consistent with the presence of large and extensive underground salty lakes on Mars." "This is an exciting possibility for those of us studying salt-loving (halophilic) micro-organisms here on Earth, since it opens the possibility that these kinds of hearty bugs may also inhabit our neighbouring planet," he said. "Halophilic microbes are champions at withstanding the most punishing conditions, complete desiccation and ionising (space) radiation."

Dark streaks on Mars could be water

The clusters of trails, which fade during winter and reappear in warmer months, could prove to be the first solid evidence of liquid water currently existing on the red planet.

Scientists are convinced water probably flowed across the surface of the planet at some distant point in history, but have only been able to detect samples of frozen water near the surface.

Should the mysterious streaks prove to be caused by small streams of briny water, they could prove crucial to scientists searching for extraterrestrial life on the planet.

Aww thats lame, does anyone really care about if it can or cant support life, no one is going to want to live there, atleast till we advance space travel by 1000% so do that first then tell me where we may or may not be able to live.

I bet NASA has found stuff way more interesting than liquid water on Mars. They just like to keep it top secret.

I'm watching it also.
So.if this is water,or salt water flowing in the summer months
at temps up to 80 f,could there be life blooming in those waters during that time?

Wait a second.... They are saying the photos may be showing flowing water on the surface of Mars? However slight a trickle or seasonal it may be, doesn't that go against what we've been told about the nature of the Martian atmosphere? I thought liquid couldn't exist in open atmosphere there?

Yes , I would say that most people here care if Mars can support life , if we find life on Mars then thats two planets within close proximity that support life , greatly increasing the probability that life is widespread throughout the Galaxy .
Liquid water on or near the surface of Mars takes us one step closer , add that to the mystery methane deposits in the Martian atmosphere and the arrows are pointing in the right direction .

Why do you say that?

I don't see any justification for that sort of comment.

Hell, set me up with everything I would need there and put me on the planet, I have been looking for an opportunity to get the hell off this planet.

I volunteer...send me send me....please...

Speak for yourself.

I would even take a trip even if it was a one way ticket.

I would want to live there, seriously.

Yeah, but it is in a salty brine form which allows it to be liquid even at the low atmospheric pressure of Mars.

I'd like to try out the fishing there!

Its not about wanting to live there , that will happen eventually when we go to exploit the resources ,it's about finding extraterrestrial life on our near neighbor .

liquid surfacewater, even rain, has been detected some time ago. Watch: Mars the new evidence on youtube.

Exactly.

The issue of using this water came up in the NASA press conference and the panel's response was that there was a lot of water ICE on Mars which could be used by humans, the significance of the news today is that liquid water would be much more useful to any (martian) life than water ice.

All the best,

The NASA press conference has now finished. I don't think it added very much to the information given in the media articles cited above, which appear to have been subject to an embargo until the start of the press conference (since most of them appeared within seconds/minutes of the press conference starting.)

All the best,

Isaac

I would love to know more about the timing surrounding this news conference. How long ago was it announced? If it was very recently put together, is that common for these types of news releases? If the press had pieces prepared to go (as an earlier poster mentioned) - how long have they been "fore-informed?" And is this common for NASA?

Thank you to the OP - it was the only reason I was able to catch the last half of the live news conference on NASA TV. And my apologies if the above information has been previously supplied - I am looking forward to digging into this a bit!

I agree. Anybody that takes the time to do a bit of research will find that NASA is very decietfull and has covered up just about every major sign of life they have found on Mars.

Water, pyramids, the whole Cydonia region, plant life, the glass tubes and even the blatant fossil that they ground to dust. Oh, and giving the Mars images the red tint.

I dont get angry easy but if NASA was just one guy that i could blame, i would kick his ass. Unfortunatly its not. And i'm not saying their all to blame. As Richard Hoagland said " the lie is different at every level". So most of them are not aware. But the ones who are aware are probably either a Mason or a Nazi.

I've taken "the time to do a bit of research", but haven't seen any CONVINCING evidence to support the allegations you make.
