Really? How can you tell, as you do not have visual clues or gestures to add to the written word. I am merely asking for a direct answer to my points rather than your points which are often not related in any way. If you see that as aggressive, then that must be caused by your interpretation of it. I do not intend it to be so, just trying to get you to stick to the points I raised.
Where as you are being rather aggressive.
No need to be condescending. Yes, you have been patient in attempting to answer my queries. I have already (politely) thanked you for that.
Let's try again, shall we?
Common? Really? Understandable? Really? I do not think it is a mistake either since we all live on Earth, and this is all we have experience of. What experience do you have which is NOT from Earth?
You are trying to compare erosion and weathering here on Earth to that on Mars. A common mistake and understandable.
Putting words into my mouth which I have not said. A common tactic. I am afraid this is an erroneous assumption on your part.
For example, you expect that the amount of dust being moved around on Mars by it's winds will be the same as here on Earth, and happen with the same speed and frequency. That's wrong. It does not.
NO, what I said is that you have gone off on a tangent about ice weathering.
You've also just discounted the weathering and erosion effects of Ice (which IS water, just in solid form), which you should not do.
And you fail to realise that if you blow small dust particles on a rock over a billion years, that rock will be worn away - however soft and small the particles. What is it you dont understand about that?
I am well aware of the time scale of 1,000 million years (a billion). However you are failing to realize that given a material's hardness factor (called "Mohs" by the way when talking about rocks and minerals), or frequency when the wind does blow and contains that material. Even given a billion years, the same rock will not have a constant stream of very soft material blowing on it 24/7.
And...? What is the point you make please?
The MERs have only explored a tiny amount of Mars itself. While we've had many orbital probes that have taken very high resolution pictures of the surface of Mars, the fact remains that the MERs have only scratched a very small amount of the surface.
So you keep on saying, but the fact also remains that you have not given me or anyone else reading this thread ANY pictorial evidence of a buildup of wind blown blueberries.
The fact remains that the majority of the surface of Mars does not have enough atmospheric pressure for liquid water. Water is present on Mars in the air and as frost/ice on the ground. It's theorized that there may be large amounts of liquid water underground where it can't sublimate into the thin atmosphere. The only place on the surface of Mars where liquid water has a chance of existing for any length of time is at the bottom of Valles Marineris because it is so deep and the pressure is greater there. That and if the water has a high salt content.
I have already said that I could be wrong about it being water. Yes, it LOOKS LIKE water and others have also thought so too. However it may be other liquid and it may not be liquid at all.
I can't help that you want to believe that a photo that you see of the surface of Mars makes you think that there is standing water there, even though it's been shown many times that it can't be because of how conditions are there, and the very fact that most of what you say is water, is in fact on a slope and defying gravity.
Not ahead of time, no. Some people have said that it is wind-blown dust particles, and THAT is how we are now discuusing the wind and whether it is possible for that to be what is shown in this image. I am saying that I do not see any evidence in the MER photos of the wind blowing much about - particularly tiny blueberries. You have not addressed this issue yet and so, until you do, I have to assume there is no evidence for the wind. Your 'scientific' arguments about the thin atmosphere and low pressure do not convince me that the wind is too weak to blow tiny blueberries about into piles.
If you want to continue to believe that you're seeing standing water, that is just fine, as you made your mind up about it the moment you saw the photograph. I'm not going to try and change your mind, especially when you've obviously decided ahead of time that everyone else that says otherwise is wrong, seem to not understand how erosion works, or want to believe that you're being lied to.
You mean those people who want to believe the scientists word.
However, I will continue to post for those lurkers and readers that are on the fence, or are wanting to understand Mars better (in a non- paranoid, non-conspiracy type of way).

Visually, scientists are supposed to draw conclusions from the images taken on Mars, the Moon, etc. Of course they have instruments too, to back up their observations. However, in this case the images do not agree with the instrumental data.
For example, you expect that the amount of dust being moved around on Mars by it's winds will be the same as here on Earth, and happen with the same speed and frequency. That's wrong. It does not.

I have not said that I expect the winds on Mars to be as powerful as the winds here on Earth. In fact you have explained this already that due to the reported lower pressure, and thinner atmosphere there is nothing like the same amount of force behind the winds on Mars. I do not see evidence for much wind at all in Mars pictures.
You've also just discounted the weathering and erosion effects of Ice (which IS water, just in solid form), which you should not do.
NO, what I said is that you have gone off on a tangent about ice weathering.
You are continuing to try to bring this into the discussion, but we are NOT discussing the breakdown of rocks due to ice weathering.

One point.
The wind-blown blueberries - where are they?
(my bolded text)
Activation of Meridiani Planum coarse-grained ripples requires a wind velocity of 70 m/s (at a reference elevation of 1 m above the bed). From images by the Mars Orbiter Camera (MOC) of reversing dust streaks, we estimate that modern surface winds reach a velocity of at least 40 m/s and hence may occasionally activate these ripples. The presence of hematite at Meridiani Planum is ultimately related to formation of concretions during aqueous diagenesis in groundwater environments
Along with taking images of the rocks thrown out by this eons-old meteorite impact, Spirit's cameras are scanning the skies to do “dust devil fishing": seeking time-lapse images of Martian mini-tornadoes. When captured by cameras on probes orbiting Mars, these mini-tornadoes show up as tall, thin white clouds, casting a shadow and leaving a dark trace on the ground as they move. In Spirit’s cameras, nothing has shown up so far but the odds are that persistence will pay off.
However, the prime limiting factor on vehicle lifetime was originally thought to be a gradual decay of electrical power generation from the solar arrays, as Martian dust built up on their surfaces. But while there has been "some degradation,” Squyres said, “it is flattening out.” One possibility, others have speculated, is that the rovers' bumpy progress is shaking some of the dust loose.
The shapes by themselves don't reveal the particles' origin with certainty. "A number of straightforward geological processes can yield round shapes," said Dr. Hap McSween, an Opportunity science team member from the University of Tennessee, Knoxville. They include accretion under water, but apparent pores in the particles make alternative possibilities of meteor impacts or volcanic eruptions more likely origins, he said.
Mosaic shows some spherules partly embedded, spread over the (smaller) soil grains.
(my bolded text)
"We see these strange round objects we're calling "spherules" embedded in the outcrop, like blueberries in a muffin. The outcrop erodes away as it gets sandblasted, and the spherules (which seem to resist erosion better than the rest of the outcrop does) fall out and roll down the hill. Weird." said Dr. Steve Squyres. The spheres may have formed when molten rock was sprayed into the air by a volcano or a meteor impact. Or, they may be concretions, or accumulated material, formed by minerals coming out of solution as water diffused through rock, he said on a February 9 press conference.

All I can say is that I have seen probably hundreds and possibly thousands of NASA, JAXA and ESA photos which I consider to be poor quality - even for 1.3M pixel phone camera shots and I do not expect NASA to be spending their/our money on mass-produced phone camera chips. If scientists will be using the same images for science, then I expect they will be taking some high quality pictures of these foreign worlds. This is what my common sense says. What it all boils down to is that I just dont believe that much science can be done looking at those released photos.

If your livelihood and your families continued income required you to swallow the mainstream understanding, then you would probably want to do that for those you love. There are a lot of people working on secret projects and how often do we hear about them..... not often.
And when we find a fossil, NASA destroys if with the RAT - just in case there is any evidence left behind. I have a feeling that you will be searching for a long time for evidence of that teeming life millions of years ago. It is obviously easier to believe that there is the possibility of life in some past era. Science has accepted that there was likely to have been water on Mars in the past and so it is safe for everyone to believe that some time in the future, it will be confirmed. Then it will be party time.
What I do believe, is that they are going to find remnants of marine life in Mars past. Fossil shells, perhaps more, but my money is on the fact that Mars had oceans probably teeming with life, far, far in the past. We need to figure out what took away it's atmosphere.
Yes, how stupid of me.... Of course. What I learned at school is definitely what I should be trotting out now. Oh well, I will have to remain stupid then, because my experience has taught me that not everything I was taught at school is correct. Science has moved on. Current thinking is not what it was then.
C'mon now, don't let all the scientific knowledge you learned in school leak out of your ears. You know that with the atmospheric pressure of Mars, that no body of water could ever stand very long. It would look just like the effect of dropping dry ice (carbon dioxide) in water on Earth. Over in minutes.
Smoke and mirrors. Actually, I do not think we are talking about satellite images here but rover images taken on the surface of Mars. Those MER IMG photos are not even worth the space they take up on the PDS.
You haven't seen the HiRISE images from the Mars Reconnaissance Orbiter? They are so large and hi-res, your computer will be struggling to display them. hirise.lpl.arizona.edu...
