Sand dunes but no beach; a Martian breeze
oilpro ^ | 22 hours ago | Brian Ricketts

Despite the obvious similarities between Martian and Terrestrial dunes, one in-depth analysis has led a couple of researchers (Gary Kocurek and Ryan Ewing, see below) to suggest that there are also important differences.

Mars when water was abundant, the Noachian Period 4.1 to 3.7 billion years ago, or perhaps less, much less.

We must not disturb the Oyarsa on Malacandra!

Perhaps something awaits that is of greater value than oil or water...

The Spice must flow.....

My thoughts on Mars: 1.) Mars should make us all very very thankful for all those wonderful greenhouse gasses that give us our thick beautiful life sustaining atmosphere that liberals are always trying to get rid of. 2.) It would be awesome if we could redirect a giant watery comet into a Martian ice cap 3.) Martian soil is allegedly comprised of vast amounts of highly reactive superoxides (vast quantities of Oxygen IOW) and superoxides are known to release oxygen in the presence of H2O as in the case of potassium superoxide found on submarines and in certain oxygen tanks.

With the spice of Arrakis I could navigate the universe.

Even if there were “fossil fuels” on Mars, by the time it was economically feasible to extract it and get it back to Earth, there would be no point because fossil fuels will be a thing of the past by then.

1.) Mars should make us all very very thankful for all those wonderful greenhouse gasses that give us our thick beautiful life sustaining atmosphere that liberals are always trying to get rid of.

The atmosphere of Mars is 97% carbon dioxide - which is a so-called greenhouse gas. So even if it has only 1/100th the atmospheric pressure, there is still - in absolute terms - far more carbon dioxide there to trap heat than in Earth's atmosphere.

I believe the assumption is that the Martian elemental composition is pretty similar to Earth’s. What they need to find is are some nice big caves to set up shop in.

Ahem. Burn them to create CO2. Move a couple of water asteroids their way. Seed the planet with plant seeds.

Earth 2.0

PS. Always thought fossil fuels are not fossil fuels. I think they are asteroid juice. Star juice. Either you understand or you don’t, but coal is charcoaled forests. Gas and oil.... cometary remnants.

I think hydrocarbons are a product of high temperature high pressure chemical processes occurring in the earths crust and mantle.

I think you are right but cometary juice is what allows the chemical process. That and the carbon cycle.

Unless we’re going to discuss the monkey face on the Plain of Cydonia, this thread lacks merit.

Without a viable magnetosphere, any hope of terraforming mars is futile.
