Images suggest Mars once had lakes.
LONDON (UPI) -- Three billion years ago, Mars was warm enough to sustain lakes that were as wide as 12 miles, scientists at Britain's Imperial College said.
Satellite images suggest Mars had a warm and wet history during the Hesperian Epoch and then lost most of its atmosphere and became cold and dry, the researchers wrote in a recent issue of the journal Geology.
Images from NASA's Mars Reconnaissance Orbiter suggest Mars once had lakes as wide as 12 miles along parts of its equator.
Volcanic activity, meteorite impacts or shifts in Mars' orbit might have warmed the planet's atmosphere enough to melt ice into lakes. That would have created gases that temporarily thickened the atmosphere, trapping more sunlight and warmth, Imperial College researcher Nicholas Warner said.
"Scientists had largely overlooked the Hesperian Epoch as it was thought that Mars was then a frozen wasteland," Warner said. "Excitingly, our study now shows that this middle period in Mars' history was much more dynamic than we previously thought."

Wes, I was going to post a vid on here, but it's over an hour long. You can get there from the link instead. There may be a truth to the secrets behind Mars. I have always found this story very intriquing though. Not that I believe, cause I wasn't there, but it made me think outside the box nonetheless. Cheers!, Slith www.themarsrecords.com/boriska_boy_mars.html

there is no doubt really that mars had some form of life. the question i think is....did it evolve beyond micro-biotic life?
the problem with mars is that its life supporting eras were for shorter than ours. we had billions of years compared to mars's few hundred million years. at best mars had some very primitive life like sea dwellers and at worse nothing but microbes.
the strange structures on mars if they do turn out to be made by intelligent life will have been by a species not native to mars.
