Earth and Mars are converging for a close encounter at the end of January 2010
Sometimes, pale blue orographic clouds can be seen hovering above ancient volcanoes on Mars.

I always thought that the clouds on mars were a result of dust rather than water/ice evaporation. Ive only just started to get interested in astrology and star gazing so excuse my lack of knowlege.
So people now accept that there is water or water ice on mars?
I think you can see where im going here. Would it be enough to support any life?

You wrote "astrology", was that what you really wanted to write or was it "astronomy"?
Water vapour clouds on Mars have been known for some years (one of the probes orbiting Mars even has special filters on its camera to better show these clouds), and according to some scientists, what is happening is that the water ice on the south pole sublimates into water vapour, creates those clouds, the clouds move to the north and then it snows on the north pole, and this process would explain the periodical change in size of the polar ice caps.
Liquid water has never been identified on Mars, as far as I know.

This is pretty irritating.. Why did it take this long to figure out there was water on mars. It's so obvious there is, and based on theories oof how water got on earth there is no reason to think it wouldn't exist pretty much everywhere in our solar system,
