Flowing Water Present On Mars, Say Scientists

[Gigas]

Ridley Scott director for the new mars movie said he was told of this water by NASA months ago.

Then there was 1877 when Italian astronomer Giovanni Schiaparelli who announced Martian canali. Later Percival Lowell announced the same canals. So, canals must mean water.

Mars is the planet of war which is a good name for a fractured world destroyed by advanced weaponry.

I didnt check marsanomalyresearch for really a long time.

But talking about water.
What to make of this?

Standing water?

Ridley Scott director for the new mars movie said he was told of this water by NASA months ago.

Yesterday I found a NASA page from last year that, apparently, shows one of the images used on the paper that resulted in this week's press conference, so they probably knew about this for a relatively long time.

Also, the Nature site where I found the published paper says that the paper was sent to them in April and considered good for publishing in August, so, for the scientific world, it looks like old news.

PS: I will add the links later, I don't have the time now.

Edited to add the links and to say that the image on that NASA page was used in a previous paper from Lujendra Ojha, the graduate student of the Georgia Institute of Technology that is the main author of this paper published on Monday.

Lunica, thanks for the input on this! Although I am a strong advocate for there bring lots of "stuff" on Mars, I just cannot see any liquid water in this pic. Also, to me, the water area noted in the pic has a sloping appearance, and if so, would not retain water anyway. But, there does seem to be a lot of fine sand on the surface in the area, which could be relative to flowing water deposits.

Nothing to see here, move along folks. Keep moving.

There are several things to see on that photo, but not water.

When they changed the coloration from red to blue, it sure made it look like a puddle of water.  I think it is significant that the rover did not drive through the crater, like there was concern it may become stuck.

That's the problem with colour, people associate colours to things and, when seeing something with a similar colour think they are looking at the same thing without thinking.

Water is transparent, the colour of the photo shouldn't make a difference.

I think it is significant that the rover did not drive through the crater, like there was concern it may become stuck.

Why would they drive the rover through the crater, specially with all those rocks near the crater rim?

I certainly am no expert on what I am about to mention, but..............has anyone else given any thought to the Rover tracks? Is that the type of tracks one might expect to see, if driving in "arid-as-desert" sand??  Of course, we do not know the context of normal Martian soil, but to me, these tracks have the appearance of having been made on relatively moist soil. There are a few places in the tracks where it looks as if some of the soil might have stuck to the Rover wheels, and has been lifted out of the track.

Because of the way the tracks do appear to be so firmly well formed, this Martian ground is something other than simple sand, and likely includes some moisture, doncha think??

Plus the crater is six meters across.  With no depth of field on the two dimensional photograph, the crater looks shallower than it really is.  It looks to be over half a meter deep with a steep drop off where the rover drove up.  The left wheel went over the edge, and a sensor probably gave the 'too steep' warning prompting the computer to turn the vehicle around.

No, I don't think so.

Have you ever worked with cement powder? Being an extremely fine and dry dust, like what we see on Mars, it acts exactly in the same way.

The problem is not the temperature, it's the pressure.

As a pressure-cooker reaches higher temperatures because of the pressure, a lower pressure results in a lower boiling temperature (that was the old method used to know the altitude, the time it would take for a specific amount of water to boil in specific conditions), and at the atmospheric pressure present on Mars water boils at the surface temperature, so pure water, theoretically, cannot exist on Mars' surface.

At any given location on Earth, the air pressure can vary about 10% whereas on Mars it can vary by as much as 50%. Mars' atmosphere is mostly carbon dioxide and therefore behaves differently than Earth's mostly nitrogen and oxygen atmosphere.

Maybe one of the Rovers took this pic - I do not know whether pixelation is involved in this or not. And no, I do not have the specific link for this photo, as I got it from social network sources!

The water on "Mars" does seem to be quite clear!!!!

Cumulative evidence from Mars now indicates that ancient water on mars was ph neutral (conducive for microbial life) and later liquid flows we see were sulfuric acid.

It appears that vulcanism took a much different path than on earth by ejecting corrosive elements which affected the surface and atmosphere of the earlier more placid and richer atmosphere period.
