And what evidence might that be?
If the atmosphere was denser in the past, the gravitational attraction of Mars would have to have been greater also, meaning that the mass of the planet has radically decreased since its "watery" past.
The present atmosphere of Mars has a pressure similar to the Earth's at 100,000 ft., or between 4.0 and 8.7 milibars. This is all the atmosphere that the planet Mars can hold, due to its gravitational attraction (about one-third that of the Earth), and tempreature. Water at this pressure boils at very near its melting point, yet there is very little water even in Mars' atmosphere, something like 210ppm.
It would appear that the probability of water existing on Mars is largely supposition.
"That theory was proposed in "Worlds In Collision" by Immanuel Velikovsky..."
Did you also read 'Ages In Chaos' and 'Earth In Upheaval'?
Velikovsky's unpublished writings can be found on:

Once the core cools, water soaks in like a sponge.
Thanks for the link!
You're welcome. It's nice to hear from someone who knows the name, hope you enjoy the site, it's packed with the fascinating science and videos of the great man whose work I have been studying for many years. The theme of 'Ages in Chaos' has been taken up on the following site:

See: The Hyksos. The Papyrus of Ipuwer confirms the first contact the fleeing slaves had with the 'Shepherd Kings' - the Amalek, (nomad arabs) at the time of the Exodus.

That theory was proposed in "Worlds In Collision" by Immanuel Velikovsky sometime around 1950. An interesting theory, and he presents lots of evidence which seems to point that way. A pretty good read for science buffs.
I'll go that one better....if there was water on Mars, where'd it go?
How about...it's right here in plain sight....on Earth?
BINGO! Remember the FLOOD?
Noah and his party were Martians!!! Sheila Jackson Lee has found her ancestors!!!
Noah being Martian was a slightly sodden attempt at humor. Ms. Jackson Lee has made reference to U.S. astronauts placing the American flag there.
I hope the Martians can live with the low-flow, low- capacity water closet, which is Algore's only contribution to mankind my assiduous research into his career has been able to document.
Yes my friends, Al is the principal reason why so many Americans are four-flushers.
It is expressly forbidden to photograph any member of the Gore Family, the Clinton Family, or Martha Stewart, from behind. (I am sure some of my Freeper pals think I am kidding.)
No, it wouldn't. Outgassing from volcanoes (the same source as most of Earth's original atmosphere) would have layered Mars with a dense atmosphere in the beginning, even if it didn't have the gravity necessary to *keep* the atmosphere indefinitely.
Boy th'wye, Hydrogen Dihydroxide is a die-njerrus kimical, stye a-wye fummit!
Okay, I'll bite -- why would you want to equate something like the evidence for water on Mars with something like "Global Warming"? Or is every scientific conclusion equally ridiculous and agenda-driven in your eyes?
Thought for a moment she might have belonged to that other famous Jackson family...sodden attempt at humor, that's a good one...US Astronauts placing the American flag on Mars...well, why not? I want to live long enough to see a space colony on the Moon, if only to prove to the mooselimbs allah doesn't live there and throw stones at us...
I was aware that the english language had been tampered with by you guys over there, but only now do I realize to what extent.
Nigthdriver,
The poster named Ichneumon beat me to a reply, but the over-all picture goes something like this:
Mars clearly had an active volcanic past. In fact, the largest volcano in the solar system (Olympus Mons) can be found on Mars. The early influx of comet bombardment, coupled with volcanic outgassing, would have kept the Martian atmosphere thicker and warmer than it is presently. While you are correct that given the mass of Mars, it could not KEEP this thick atmosphere indefinitely, the rate of "leakage" would require many millions of years for all the air to bleed away. So, for a LONG, LONG time, Mars most likely had a warmer, thicker atmosphere, as well as frozen, liquid and vapor water at or above the surface.
Again, do not look at the current condition of a system, and assume that it existed in a steady state for its entire history. Things like this are quite dynamic, before settling down to a state that can be in equilibrium.
Just looking at such a massive volcanic cone as Olympus Mons, you can tell that the actual planet was warmer, and volcanically active, even though no active volcanoes are currently observed today. When you see such huge volcanoes, natural questions arise, such as "Where did all the gas they must have spewed out go?", "How much gas must have spewed out?" and "How long did it take for the gas to disipate?".
When you see channels and troughs that look "precisely" like those on Earth that have been carved by water, especially when you can get spectrographic measurements that suggest water produced minerals exist in those locations, occam's razor strongly suggests that water existed on the planet's surface.

Fabulous pix! I especially liked the one titled "Water Seapage".
