Wind erosion and water erosion look quite similar. Now throw in extreme temperature fluctuations.

“It has no magnetic field, so the solar winds just evaporated the water away.”

The water didn’t simply evaporate. It froze. However, at some point the surface temperature was high enough to have running liquid water, at least for some portion of every year, and this happened for longer than it should have taken the solar wind to give Mars the atmosphere it currently has. Unless our prevailing geological models or something else are not quite right.

“Wind erosion and water erosion look quite similar.”

Sure, in some cases, and with a casual examination. But not in all cases, and not when examined closely by scientists who know the difference.

“started trapping all their Carbon Dioxide”

One problem with this speculation by the scientists that loss of CO2 caused it, is that the Martian atmosphere is still 95% CO2. So if Mars was losing CO2, it apparently wasn’t losing it any faster than it was losing the rest of its atmosphere.

Why did Mars dry out?

Obviously, his consort, Venus, was nagging him about spending too much time in the bars. He had to prove to her that he wasn't an alcoholic. So, he stopped drinking for a while. Women can be a good influence on men like this...

Mars was robbed, by interplanetary travelers who thought that the Earth needed more water, and so, they set about transferring the water from Mars to Earth, which is all documented in the great flood in the bible.

I’m increasingly skeptical of university trained ‘scientists’. There seems to always be an agenda.

The low gravity of Mars along with the its loss of a magnetic field probably contributed to some of the water loss from the planet. There may still be some ice well beneath Mars’ surface.

I thought Mars lost most of its atmosphere because its gravity wasn't strong enough to hold it. Which would explain what happened to the water. Some of it would always evaporate and break free of Mars's gravity instead of raining down again.

BTW, when they say "water," do they mean H2O or any type of liquid?

And how would they know what type of liquid Mars had?

So evil human beings don’t have to be involved to get climate change? Huh.

“Plus, they’ve mapped our oceans, they are just keeping the findings secret because they think you can’t handle the truth.”

The inhabitants of Atlantis don’t want to be bothered by a bunch of tourists. They have an understanding with our Deep State, because the Atlanteans are the original Deepest State.

Water was deposited on Mars when it was expelled from Uranus.

There once was a rocky, water-world in the orbital space between Mars and Jupiter. It was a bit larger than Earth. and had quite a lot of liquid water. It was struck with one of the small-ish remaining “planetesimals” left over from the solar system’s formation.

The world was shattered from the collision, and the resulting debris formed the asteroid belt, and birthed numerous comets, many as messy mixtures of rocks, dust and water.

The planet seeded all the other planets with comets, stony and iron-y meteors, and watery comets.

Earth retained a lot of its water deposit. Being smaller, and not having a protective magnetic field, Mars’ lower gravity and exposure to the solar wind bled off its atmosphere and water allotment before large-scale life could develop.

On the other planets, the influx of meteors and wet comets made little difference, and was quickly absorbed without much effect.

It is possible that ruptured ocean-world had a civilization before it was destroyed.

I call it “Atlantis.”

Did not read article.

I suspect however, it was all the Martian SUVs that they were driving. Global Martian Warming. Evil Martians! They must have been conservatives!

Mars dried up because their MASA (Mars Aeronautics and Space Administration) funding ran out.

Mars has an inner metal core similar to Earth which early on granted Mars a sizeable magnetic field. However due to it’s much smaller size and further distance from the Sun, the core cooled down and it lost the magnetic field.

Earth’s strong magnetic field protects the atmosphere from solar radiation. Without it, this radiation would blast our atmosphere out into space. This is what happened to Mars.

Mars probably had a thicker atmosphere at one time that allowed for liquid water, but as the atmosphere was destroyed by the Sun, the water both evaporated into space and froze in the soil.

Know this, Mars can never be terraformed, because we can’t make the core molten and spinning. So just laugh when you see all these goofy millenials and gen Z ignoramouses put all their hopes and dreams into terraforming Mars for humans to colonize.

Well that’s a theory all right. My understanding of the asteroid belt is that Jupiter and Mars created a tug of war that keeps the objects in the belt from coalescing. It’s the same reason that some of the rings of Saturn don’t form more moons, as its own moon system shepherds the rings into their stability.

Scientists trying to figure out what happened one billion years ago to a planet 140 million miles away.

Scientists are starting to annoy me.

The telltale tracks of past rivers, streams and lakes are visible today all over the planet.

And the canals. I TOLD you people there were canals but would anybody listen? The question is what happened to all the gondoliers, isn't it? Did they all migrate to Venice?
