Carbon deposits found on Mars.

"...The discovery of carbonate suggests that the atmosphere contained enough carbon dioxide to support liquid water existing on the planet's surface. As the atmosphere thinned, the carbon dioxide transformed into rock form.

NASA says future missions and analysis of other sulfate-rich areas on Mars could confirm the findings and help to better understand the planet's early history and how it transformed as its atmosphere was lost.

Tutolo says scientists are ultimately trying to determine whether Mars was ever capable of supporting life—and the latest paper brings them closer to an answer.

"It tells us that the planet was habitable and that the models for habitability are correct," he says..." "

Oh spare me; another false analogy/comparison; what did you put into the models make your answers agree with your predisposed assumptions?

Every time NASA needs more tax payer funding, they come up with some "incredibly important, ground breaking discovery" that justifies further and greater investments. You can count on it. (PS, that's not just my observation, that's from an actual NASA employee!).

Phys.org, Popular Science, Popular Mechanics, The Daily Galaxy, Live Science, and other similar sites, really do a disservice to science by posting clickbait titles and by not giving the total story.

I have clicked on what looks like an interesting scientific article only to discover, after looking at the actual scientific paper, that the author of the clickbait article got it wrong on so many points.
 
Maybe I'm wrong, but I was under the impression that mars was geologically dead. Therefore, a weak magnetic field, thus no way to hold onto an atmosphere.

That's why I don't think the planet can be terraformed. No way for the planet to hold onto an atmosphere.
 
A whole new market for @TiGeo to sell HPL too.

Wonder what the shipping costs would be.

Edit: or was it somebody else that was selling HPL?
