Possible Ice II

Stop dragging your cloudy baloney in the field of your choice!

I feel like slicing some baloney. Talk to the weatherman brother.

Fred

This is to all on the forum. I am also a salesman. Do not tell me about the labor pains show me the baby.

You want to give me words? Not a chance brother.

Darwin. Suggest you might like to try this.

To return to Mars and weather, and NASA, this is the link for the animation Fred gave us.
A couple quotes which take notice of my question, as the image was a smoke-in-the-darkened-room effect, and I was concerned until I read this statement and a few additional on the linked page. The images consists of two parts, and I use similar techniques to view items. I would never have published such a two image assembly myself. Not to be unnecessarily critical of NASA. They have few resources onboard the Phoenix for enhancing and reworking the results. I knew it had to originate at the ground after arrival on Earth.
Where on Earth this arose as a combined image, I couldn't have known if I hadn't read the story.
As you can see, again, I am a little slow with the news updates.
Thanks Fred, it takes care of the trail I was generating, as to the image source.
From the page link at the source,
"
These have been shown superimposed upon a full image of the telltale from Sol 13 for context. The frost on the mirror sparkles in low-angle light from the sun, which is barely above the horizon at this hour.

A hue enhanced view of the image, with the obvious dichotomy of a first image, in red, and the second, frost, or noise figure, in white. Only the arm and mirror were in the first image. The frost was added later. Curious, but a path back to the source upon reading the link.

Nose to the weather at all times. Thanks.

If this is common on Mars, this is the probable cause for dark slides, landslides, streaks, and more. This is very weighty. We need a measuring scale for the actual figures involved, over-night, and over time.

Thanks for that image of deposited frost in post #83, Hort.
Does it evaporated daily and is redeposited or does it persist?
It will be interesting to see how deep it can get as the temperatures drop as the Sun gets lower in the sky to finally drop below the horizon.

sol 44 - 86 changes under the lander:

There are changes.

Plenty of frost imagies from Spirit today, from the years passed

An example from opportunity, iced trails:

So now geniuses have seen the light!

eS

Is it snow or what?

MORE SNOW

The Sun light is from behind, as you see by Rover's shadow.

If they could find out why the ice Grows on the leg, so things about mars might become clearer.

My guess would be that the thrusters melted some hydrated salts, and that they are now the nucleus for the ice formation.

Damn, you guys just do not get it. Mars Atmosphere is thin and cools rapidly without solar radiation. The shadows are cold, cold, cold. Metal in shadow gets really cold, cold, cold.

For the 19 millionth time. An earth comparison is like a liquid nitrogen tank on Earth. Take a good look. See any similarities? Duh. Either you guys do not read or can not understand. Shut-up John

The bottom line. The metal not exposed to solar energy accumulates water vapor from the sublimating ice exposed during landing.

Image 1 Earth Liquid Nitrogen tank and guy scraping the ice off. Fluffy stuff, like snow.

Image 1

You seen the legs I hope, will not post an image.

Next, that is not snow. Never assume that what looks white is white. Always consult with the image gods or the profit Hort and ask, What is White and What is light Tan.

I suspect what you are seeing is last years dust storm deposits in the dunes at the edge of Victoria. It collects there. That is why there are dunes. No precip at the equatorial regions so far.

Fred

That should read no proof of precip at the equatorial regions. I suspect that ground water eruptions vapor or liquid can produce nocturnal localized snow events. That is speculation. I will show you how to do it.

Hort can you tell me what is white is white? Lets see what he says. Now I know for a fact the old chap has not slept much. I have been with him all night. A few hours, maybe. A marsaholic like me.

If you get board, Is it white.

Fred

"For the 19 millionth time" Hmmmmmm I only count 16 million posts from Fred. Meebee the moderator IS doing something.

John

Well, for smoothness I give you a 10
Getting your point across, another 10
Adding something to science, a big fat 0. Go figure.

Fred

Fred, is it in your fridge snow or frost?

The problem with your analogy is that the material is isolated, not on all the parts that would be affected with your theory.

I can even see the sun on the leg with horton's giff.

Something was melted, and that something is now acting as a sink, absorbing, or acumilating, the minute moisture, (ok not moisture), ice crystals, or such.

Some minerials become blobs with heat, sufates for one, then, the blobs would shrink upon freeze drying. Then grow, like the veggies do in my freezer, covered with frosty ice particles.

or not.

Freddy, my boy. I'm here to learn, not teach. As far as what YOU have taught, GIVE IT A BIG FAT "0". Go figure.

es. In analysing any image check what filter is used.

Mann - I think you are spot on. Copied from Phoenix on Mars thread with apologies for cluttering the bandwidth: 'Interesting that the 'clumps' are on one leg only. One theory is that dust and ice were blown onto the leg during landing. If the regolith does indeed have the rather impressive thermal inertia properties implied by the presence of well bonded permafrost only 2 cm down, then any regolith dust deposited on the leg could insulate ice that deposited on top from any heat transfer from the leg. We would therefore have a perfect shaded and cold location for frost to deposit and resist sublimation - so the clump would grow.'

John. Amen to that.

Brian, if you were that demanding toward the "scientists".

I hope I do my fair share of work, and let others to do the rest
