Nightime Clouds in Martian Arctic

To me, this amount of water vapor appears in excess of what we've always been led to believe; that Mars is a cold, dry and harsh planet that cannot support life. Perhaps through the careful dribbling of information such as this, the mainstream scientific communities paradigm is being shifted towards possibilities, far, far different?

I've performed three searches on this subject here at ATS and have come up empty handed, so if these vid's already have an associated thread, my apologies to all!

See the below link. We already know that snow is falling on Mars, so there obviously have to be clouds. I would say that we haven't been misled, but rather may have been misinformed about the discoveries already made by NASA on Mars.
NASA in 2008 - Snow Falling on Mars

I've written articles about Water on Mars and the recent discoveries of water and I've done a lot of research for them. You should read more about the recent evidence that seems to show that there is briny water currently flowing on Mars!
So many fascinating things are happening! In fact we may be close to finding signs of life (and for you conspiracy theorists, actually acknowledging it). This is a great time to be following Mars!

Reasons why there can be no life on Mars

1. It's to cold.

2. Lack of Atmospheric pressure.

3. Cosmic rays and solar radiation constantly sterilize the surface (UV light breaks molecules apart).

4. Lack of liquid water (due to reason 2).

5. To far from the sun meaning a lack of solar energy even if plant DNA could survive the onslaught of radiation.

So if we take all of these bullet points into account we can assume that Mars is devoid of any surface life as we know it, now the hard part is people coming to terms with this.



Do you realise that points 3 and 5 kind of contradict each other



In regard to point 4 (lack of liquid water)

Do you realise that for a very short time of year in the Northern Hemispere summer it warms enough for ice to become liquid for very short amounts of time.

Also due to the larger wobble of Mars, there are times where the poles are more directly lined up with the sun and leads to very slight melting of ice although because of the lack of a magnetic field the suns radiation will make the water evaporate very quickly, however it could remain liquid for short amounts time.....





In the area around the Phoenix lander, the high levels of Perchlorate act as anti freeze.




Images from the robotic craft show what appear to be liquid droplets growing, merging, and dripping on the lander's leg over the course of a Martian month.




The water can stay liquid even in the frigid Martian arctic because it contains a high amount of perchlorates, a salt "with properties like the antifreeze used to melt snow here in Michigan," said Renno, who will present the work next month at the 40th Lunar and Planetary Science Conference

If you follow the link to the NASA page you will see it was last updated in 2008, they did not wait until 2011 to tell anybody anything. This thread was just made in 2011 nothing is being hidden.

It didn’t. This thread is just woefully outdated. These videos have been up on NASA site since 2008.

Just curious...which of these explanations do you think accounts for the fact that they released photos for how many years showing a red Mars before they finally admitted they were shooting through a filter and the colors shown were not the correct ones?
Do you think they needed all that time to research whether or not there was actually any purple in the American flag plaque they kept photographing?
Or do you think they just did not want to release it early for fear they would discover that the American flag plaque did indeed include purple and they would look silly?
Or perhaps they wished to mislead the public and convince everyone that with red soil and sky that Mars was indeed a truly alien planet in no way like the earth?
No. Scratch that last idea. NASA would never intentionally mislead anyone. It must have been one of the first two possibilities I listed. Which one gets your vote?

NASA now freely admits (ok, not freely admits, but by NASA standards it's as good as!) there is flowing, liquid water on Mars..announced in the last few days.

They are calling it 'Brine' though, but would anyone argue that the Dead sea isn't liquid water? That's Brine too.

A year or two ago, i can think of a few members here that would had a field day ridiculing any other member for saying there was liquid water on Mars..probably did too.

Here's a link: www.space.com...

the interesting thing is as phage said, the reported pressure is too low and the temperature too low for liquid water to exist on the surface. With that said, and Nasa admitting there is liquid water, seems to me the reported pressure and temperature must be wrongly reported; or Mars has different laws of physics.

We cut the details and just say 1% of.

That sort of means negligible, in easy to understand terms.

You are doing the math wrong.
edit on 27-1-2012 by Illustronic because: (no reason given)


The numbers I quoted above are from wikipedia. Your 0.6% number is close. The actual pressure is 0.636 kPa and the percent is 0.627 if you use 3 significant figures. The math is straight forward. Divide Earth Atm pressure by Mars to determine the factor to multiply a comparable wind speed on earth for formation of a dust devil and you get the 159X factor.

Earth
Atmosphere
Surface pressure 101.325 kPa (MSL)
Composition 78.08% nitrogen (N2)[3]
20.95% oxygen (O2)
0.93% argon
0.038% carbon dioxide
About 1% water vapor (varies with climate)

Mars
Atmosphere[6][9]
Surface pressure 0.636 (0.4–0.87) kPa
Composition
(mole fractions)
95.32% carbon dioxide
2.7% nitrogen
1.6% argon
0.13% oxygen
0.08% carbon monoxide
210 ppm water vapor
100 ppm nitric oxide
15 ppm molecular hydrogen[10]
2.5 ppm neon
850 ppb HDO
300 ppb krypton
130 ppb formaldehyde
80 ppb xenon
30 ppb ozone[citation needed]
18 ppb hydrogen peroxide[11]
10 ppb methane[12]

Water without hydrogen is not water, it is a free oxygen radical. CO2 is not water.

As previously stated, water as a liquid cannot exist on the surface of Mars unless the pressure is greater than the vapor pressure of a water molecule at the corresponding temperature. For example, at 0 degrees C, the vapor pressure is 0.6 kPa, so at 0 degrees C, water can only be in vapor phase. However, mars is much colder which means water is solid, not liquid.

So the only logical place for liquid water on Mars would be at a very low point where the ATM pressure is high enough to keep the water from evaporating and warm enough to keep it from freezing. So far, these places have not been found.

But Nasa says there is an outflow of water on some slopes as evidenced in some Nasa photos. However, these photos are not located in low or warm areas, which leads to this conclusion.

1. either the water identified is not water.
2. Mars has a higher pressure than reported.
3. Physics is different on Mars.

Take your pick.

There is not a linear relationship between air pressure and the force exerted by air movement. Essentially you are attempting to calculate the difference between indicated air speed on Earth as opposed to on Mars. The surface pressure on Mars is equivalent to an altitude of about 115,000 feet on Earth.

On Earth the wind speed of a large dust devil can reach 60 mph but it doesn't take that much wind to move dust (obviously) and the dust on Mars is very fine and very dry, more so than that found on Earth. Using an online calculator it is found that on Mars' surface it would take a wind speed of about 190 mph to produce the same amount of force as a 60mph wind on Earth. That's pretty windy but the very fact of the low density also makes those high wind speeds possible.

The CO2 in Mars' atmosphere probably does help keep it warmer that it would be than if there were a lower percentage of it. But, since the atmosphere is so thin, not much.
