How about giving us the more reasonable explanations for what those droplets are? The other explanations have been presented, but you haven’t given the more reasonable side of the real scientists actual conclusions. The polar ice caps on Mars are not made up of water but are composed of Co2. Liquid water cannot exist on Mars because of it’s thin atmosphere. It would boil away instantly.The Phoenix probe landed in the northern latitudes of Mars to examine the icy regions of Mars. Remember the ice is not water ice, but Co2. The liquid droplets are therefore most likely droplets of Co2 which are condensing, but it isn’t quite cold enough for it to freeze.You shouldn’t suppress and only present the unintelligent sensationalist side of the story.

But on the contrary, the drops merged into larger drops. Is it so supersaturated salty solution!Therefore, when these drops became larger by absorbing some humidity from the atmosphere, it could be possible that ((such drops were not formed by the splash)), but essentially from the humidity of the atmosphere itself (as is it the condiition here on Earth, when a cold metal will have some drops formed on it directly from the atmosphere humidity.)Moreover, why is the ice restricted to the two poles (like that on Earth), and on the tops of some high mountains (like the situation of the Earth mountains)? If it is very cold and freezing on Mars as a whole, then the entire planet should freeze, like some of the remote planets of our solar system.universeandquran.t35.com/#The_planets_Are_Inhabited_ universeandquran.t35.com/new_page_2.htm#The_Journey_to_Mars_Is_Successful_universeandquran.t35.com/new_page_2.htm#An_Anticipated_Meeting_ Sat 21 Mar 2009 15:17:19 GMT+1 mm http://www.bbc.co.uk/blogs/today/tomfeilden/2009/03/life_on_mars.html?page=70#comment7 Why do people have to link existence of life with water, air, temperature etc basically what is required on Earth for man to survive or for creation of life. What this people refer to as 'Goldilocks zone' around which it is possible that life can exist. Why is it not possible that alien life form don't require what we require on earth to survive. It's certainly not beyond the realms of possibilities and infact is the more possible scenario where alien life is present without the prerequisites of water, oxygen etc. This find is nothing to get too excited about as it won't be a conclusive proof of anything.

I am posting them on my website (Nilton Renno) at the University of Michigan for any interested person to look at.

If they are droplets, the surface looks quite hydrophobic. If the surface is hydrophilic I think we can rule water out.

Droplets are rarely spherical under the influence of gravity and as has been pointed out, the wind, even with Mars's rarified atmosphere.There is also the issue of surface contaminents. Those struts must be covered with the fine Martian dust. That would serve to distort the effects of the hydrogen bonds that give rise to surface tension. Look at how droplets form on any terrestrial dirty surface. The fact that they are observably not wetting the surface very well is suggestive of how droplets form on finely dusted surfaces. I do agree the perchlorate suggestion sounds flawed because the evapourated water becomes distilled but the surface contaminents could serve to provide the necessary salts. As the atmospheric water condenses onto the struts, the contaminents disrupt the charge distribution of the hydrogen bonds normally associated with ice.

There might well be a breeze blowing the droplets sideways and into different shapes because of a lower gravitational pull.

Look at the 'droplets' on the underside of the leg - they just seem too jagged to be liquid which you'd expect to form rounder balls. And look at the two 'droplets' on the leg right above the one marked in green - they just look too close together in the final picture to have not merged. And even the one marked in green is a little odd - if it is flowing, then it appears to be flowing left to right, not downwards at all! Finally, note that the concentration and sheer number of 'droplets' on the photo make it unlikely that we'd only see one of them appear to merge through the complete sequence.I wouldn't be suprised if one day we get proof of liquid water on Mars, and one day we'll get proof of life on Mars, but I'm just not at all convinced this is it I'm afraid. Good story though!
