again this one slipped me , Fog on Mars .. a river of Fog more like

Look here for more fog.

might be a cause of those blooming early morning suns we're seeing in Gale

I doubt it, if I'm not mistaken, all the photos that show fog are of the lower areas, lower than Gale crater, and we have now many photos from orbit of Gale crater and I haven't seen one photo showing fog.

do we have an orbital shot of Gale 30 mins before and after sunrise? * sunrise hitting that specific region*

ide guess it has more of a chance forming around these times

Before sunrise, I doubt it, as it would be dark.
All the photos that show the fog do not appear to be taken close to sunrise, as the shadows are not long.

so we only have the rovers perspective on the air condition at early morning..

and they don't suggest much do they

the question I now have is , did they know of this foggy region before they decided on the landing site for the Curiosity Rover?

and if so why did they not consider a foggy region not a viable region to search?

Has there been any speculation by Nasa on the potential of life in this foggy environment, that you know of?

to me a foggy region would be the first place to search , a far higher chance to find surface water there ,if its in the air

Yes, the Mars Express photo you posted is from 2004, the landing site for Curiosity was decided in 2011.

and if so why did they not consider a foggy region not a viable region to search?

The first thing they look for in a hypothetical landing site is a flat, smooth surface, as that will give less chances of bad landing. Landing at the bottom of a canyon, even a very wide one, it's not as safe.

Has there been any speculation by Nasa on the potential of life in this foggy environment, that you know of?

No, not from NASA or from ESA.

According to page 21 of this PDF, it looks like the shape of the ground is the main responsible for the creation of the fog, not the amount of water.

not much time to plan for a mission then

No, not from NASA or from ESA.

loose lips sink ships

but feel free to speculate on the nature of the ground underneath, you do have a few clues

without reading (I will do later) would this be because of it being a deep Ravine ? temperature inversion keeping a thicker yet colder atmosphere from the warmer above ?

That's my understanding of the information on that page, lower altitudes have a lower temperature.

[funbox]

HRSC images show impressive morning fog features inside Valles Marineris and other regions of the surface of Mars.
Temperatures have been determined simultaneously to the imaging by PFS. This identifies water ice rather than frozen CO2 as the cause of the fog observations.
Numerical estimates of the water vapor pressure and atmospheric water content at the frost-point by a 1-dimensional planetary boundary layer model indicate that conditions in the planetary boundary layer can indeed temporarily favor the formation of ice particles.
The fog phenomena seem to be induced or supported by orographic effects but not directly by the distribution pattern of the
atmospheric vapor or by the regional subsurface water content.

so plenty of water formation then

I cant be so sure though , that presentation looked like it was made in crayon by a kid

You can always use the email address on the first page and ask Marco Giuranna.

One thing I like about scientific studies is that people don't hide behind a blog or an YouTube channel, they say how they can be contacted and, from my own experience, they do not have any problem replying to emails from people asking questions about their work.

[funbox]

I doubt ide get anything but derision  and i'm not really interested in whether he used crayon or felt, besides look how he danced around o2 in that article. what makes you think any retort wouldn't be the same. ambiguous

funbox

[ArMaP]

It depends on how you ask.

If you appear to be a "conspiracy nut" you are not likely to get an answer, if appear as someone that, although not a scientist is interested in their work, they (usually) answer, some 90% of the scientists I have emailed have answered me, one of them was Jim Garvin, as you can see somewhere here on Pegasus.

hello Nasa Employee

what's the odd's/potential for life and the persistence of surface water underneath the blanket of fog?

thanks in advance

FuNbOx

[ArMaP]

I would say it in a slightly different way.

Something like this:

"Hello Nasa Employee
First of all, sorry for taking your time. I read your work about XXXX and have some doubts, is the difference in environment enough to give better chances for the persistence of surface water? If yes, in which regions is that more likely to happen? And what consequences for the potential of a life supporting environment?

Thanks in advance."

[funbox]

have you been reading Carnegie books again ?

First of all, sorry for taking your time

you want me to lie straight off the bat ? ill not be ever sorry, for asking a question to an employee that publicly displays there email and besides it comes across cheesy

but with a little rewording

"first of all, no need to thank me for distracting you from real work"

I read your work about XXXX and have some doubts

no no no , I have query about what's been speculated about the fog and its corresponding environment
the only doubt I have is the pdf guys ability to use a crayon

is the difference in environment enough to give better chances for the persistence of surface water? If yes, in which regions is that more likely to happen? And what consequences for the potential of a life supporting environment?

almost the same as mine , but mines short and to the point

you should revise that apology
