And what happened to the subways under the canals?

They don’t know what mars-ological force caused the red planet to become a lifeless desert, yet some individuals cling to the belief that they can “terraform” Mars, generating oxygen and, that the unknown force will not eliminate the oxygen that the scientists work so hard to generate.

How could the Martian environment be reverse engineered? Wouldn’t it be cool to have a habitable planet close by?

More than likely the reason Mars lost it’s liquid water was that it progressively lost its atmosphere. And probably it lost its atmosphere because it wasn’t geologically active as earth was/is. What does Earth have that Mars doesn’t? A molten iron core that creates a magnetic field that deflects solar winds.

Lack of mass may also have had something to do with it.

I wouldn’t discount that. There is also the accepted theory that early in its life Earth was struck by an asteroid/planetoid with a high iron composition. This added to the mass & density of the planet while creating a disk of lighter debris that eventually condensed into our Moon.

Why, the Martian SUVs of course.

How the heck does these scientists know what happened billions of years ago?

Why are we trying to find life on a planet that has close to 96% CO2 atmosphere?

According to climate change scientists our planet is going to end and we have a .06-.04% CO2 in our atmosphere...

“Carbon dioxide is a strong greenhouse gas, so it really was the leading candidate to explain the drying out of Mars,” said Kite, an expert on the climates of other worlds. “But these results suggest it’s not so simple.”


and the science shows it is a LAGGING Indicator, but don’t pay attention to the science..................

CO2’s molar mass is 44. O2 is 32. CO2 is heavier than air, and thus it sinks.

It’s why we have phytoplankton, seaweed, etc in our oceans. Were it not the case, there would be no sustainable food chain in the ocean.

Leaving one important scientific question:

Who did this person sleep with to get this job?

Never had water. It didn’t go anywhere.

Liquid CO2 flowed. Now all gas or crystallized below (that’s ice in water terms).

Not really much of a mystery. Mars has no Magnetic field to speak of.

The solar winds pretty much has swept away any atmosphere that could be on Mars.

To terraform that world, you would first have to get a strong magnetic field going.

Not enough fluid or electrolytes?

My best guess.
