It could be, Mars gives immortality to the rovers ? Maybe a special trace gas in the air ? Rocks and sand and sand and rocks rocks and rocks for decades to come. (Joke)
We´ll see what will happen to the next Mars missions.
Rain, wind, extensive temperature differences , aggressive chemicals etc.... It makes us wonder which magic material is used for the optic system to withstand such attacks over that quite long periode.
Three components have to withstand the harsh conditions::
The optical system ( lenses in different combinations ) The mechanical systems ( everything which is depending on "movement" ) The electric systems ( energy sources in general, tiny "motors to manage focusation etc. )
And this is just one part of the whole machine. Adding the navigation of the rover, the driving devices , radio communications, scientific payload etc. makes the mission to an outstanding technical achievement.
No-one has explained how the Rovers keep their camera lenses clean. Yes, I know the lens covers are made of something special, but it must be pretty good to keep clean all the time. (didn't I read that they have the same coating as you can buy to keep rain water drops from staying on your windows?) Any special coating would reduce surface tension on the outside of the lense cover and cause the rain to form into small rivers down to the bottom and not stick to the glass. We would see those small channels of water in the following photos, wouldn't we?
Anyway, although there IS evidence of dust occasionally, there is not much and with all the dust storms and dust-devils...
Sorry NASA, in spite of your video movie of a dust devil, I still cannot see any other evidence in the environment of strong winds leaving large piles of dust/sand against the lee-side of rocks.
I cannot help but notice that in the two SOL36 images, the "rain drops" are in the same position, and the one from a few sols earlier is different. This implies, to me at least, that it is not noise. There is something either in the air or on the lense. We got that part down. Now, isn't the camera too small for raindrops to appear that size on the lense? You are comparing lenses to windows. If water is involved at all, these are probably droplets. Small droplets at that. Then again, that's just my take on what I see. I need to see an image of the ground in that area on the same sol.
Also, the comparison of Earth dust storms and Mars dust storms is...interesting. And it has nothing to do with the dust. If I can find anything, I'll post.

Do not forget what we have already discovered on Mars and try to build the debate on the basis otherwise we will sound like idiots.
Software Pyrate, it is not much other data to build on, it was the weather reports from Mars temperature, amount of sun and also wind meter showing not wind power but wind action on the surface bud you did not knew how heavy this surface or big it was.
You guys know a lot more about the crafts we have sent there (phoenix, spirit, opportunity, ect).
I was just wondering what data we have available to us other than images...I am referring to the other instruments on these crafts...i.e. temperature, humidity, ect. as this would greatly help our cause.

I am still leaning on the rain side....But all other possibilities must be ruled out before I can jump on the band wagon, and ( I hate being the devil's advocate )but...
1) the biggest argument that I see is still some kind of interference with the camera.
2) If it is in fact rain on the lens...then you would think it would start to dribble down the lens so to speak like your last image in the OP.

All clouds look the same worldwide because behind them are the same physical forces so let us know when as we see them.
Can also the identical. But it is necessary to consider a chemical compound a condensate and physical conditions. And after all the general conditions of the earth and Mars only odno-are in one star system. Other conditions do not coincide. From here it is possible to draw a conclusion that the same physical phenomena can be shown absolutely from an unexpected side. But I also do not exclude display of Martian clouds similar to the terrestrial. Here for example sandy storms terrestrial and Martian, given a satellite picture.

Может и одинаковые. Но необходимо учитывать химический состав конденсат и физические условия. А ведь общие условия земли и Марса только одно-находятся в одной звёздной системе. Остальные условия не совпадают. Отсюда можно сделать вывод,что одни и те же физические явления могут проявляться совсем с неожиданной стороны. Но я также не исключаю проявление марсианских облаков похожих на земных. Вот к примеру песчаные бури земные и марсианские,данные спутникового снимка.
NASA claims those clouds are made of ice crystals and not liquid water droplets. Shults refutes that. Shults also shows areas on the ground where he believes rain has occurred and does an experiment to prove his theory. He explains rain on Mars as being very different than on earth - thinner atmosphere - higher velocities - tinier droplets, etc - the rain comes very quickly down like a hard mist spray. He explains also how it can be in a liquid form in such a cold place as we see at Gusev and Meridiani.
As far as the Phoenix clouds and sky, let's not forget the temperature is even colder there - remember the frost formation on the equipment. (Also, frost formed on the ground seasonally near the viking landers). I do believe there are some official sources admitting snow on Mars in the polar regions- which must also be accounted for as a possibility in that area for any possible precipitation in the sky.
I seem to remember that dust storms cause a general darkening of the skies. Certainly they do here when we get them each year at a certain time. It goes almost night time dark but does not seem to produce clouds like rain-clouds at all - more a general darkness. However, i'll admit, it could be different in different areas/worlds.
In all the images is horizon plainly drawn it tells us that this is most likely a rain on the shield in front of the camera lens
These images have all the character that the other films from the Earth has so I think there is no reason to doubt. I'm sure the camera's finish is under the most stringent requirements.
We know that there are sometimes very cloudy sky on Mars, a massive cloud, so it gives the eye the way that it is raining
It is fine being a skeptic but I think the nasa guys would probably have designed it so that it did not get interference when it rolled over bumpy ground. From their point of view, they would not know what kind of terrain their rovers would be subjected to and they probably spent months testing it on Earth too.
But then again....skeptic side coming out....could just be some kind of interferance as the rover drives over a bumpy part of the path and the camera gets jolted so to speak..

I have done a couple google searches on this with the key words "rain on mars" and have only come up with hypothesis and speculations on the matter dating back to '06. But nothing solid such as these images....
While I agree this is totally rain, Has this been confirmed as such? Is there any documentation on the issue. This would be the find of the century if it is in fact rain.

Yes, I have wondered how sometimes the pictures appear with spots of white in them and at other times from the same camera, they do not have these spots of white. It would make sense if these are raindrops.
Do the rovers have windscreen wipers or some way to wipe the dust and dirt from the lenses?
Surely the cameras would be pretty well hidden and protected from as much outside dust/dirt/water as possible? If there was as much wind-blown dust as they say, any water/rain would contain some dirt in it and this would dry on the lens. Over time the lenses would become like our earth windows do if we do not clean them.
How can we reconcile these questions with what we are seeing in these pictures and in reality?
