Default Terriforming Mars. Scifi fantasy. This isn't "Total Recall"

The original "Total Recall" the remake was s---. But the idea of forming a new atmosphere on Mars is lunacy.

Very easy,terriforming, it was done in the movie , The Martian by Matt Damon !
need Mars soil, few expired sandwiches and water.
Anything grows in it!

Read Robinson's Mars Trilogy for a good treatment of what is
scientifically possible, even reasonable, for terraforming Mars. It
isn't fantasy, and it isn't beyond our scientific or technical means.
That doesn't mean doing it anytime in the near future makes much
sense. But that's a matter of social policy, not scientific ability.

Default Terriforming Mars. Scifi fantasy. This isn't "Total Recall"

The idea of 'terraforming' is on the same level as 'time travel' and therefore represents a mindset that belongs to neither adults nor children but a fictional in-between conviction. If it were for some science fiction narrative it would be fine but much like the area of timekeeping and the 'time travel' fiction that encompasses it, 'terraforming' obscures the human intimacy with natural forms and specifically the phi proportion which is a signature of something vibrant and joyous -

http://www.maths.surrey.ac.uk/hosted...nacci/fib.html

The more geometry returns to human consideration in terms of cyclical (seasonal growth and dormancy) and direct motions (for instance the evolution from child to adult), the more the intimacy becomes more loved as a balance and as an evolutionary story.

This is not an argument against terraforming but as the realisation of the natural treasures in front of humanity become more obvious, the more the mental tinsel like time travel becomes less. Astronomy is a stadium in which life plays out, not a cistern for wishful thinking.

The oxygen leaked off the planet what, a billion years ago? How will they keep it there now?

It needs to be constantly replaced. But the leak rate is low- how long
do we need to keep it there? It's not like there are going to be any
humans in millions of years, and it takes hundreds of millions of
years to lose significant amounts of oxygen.

It
isn't fantasy, and it isn't beyond our scientific or technical

means.

ability.

years to lose significant amounts of oxygen.


The replacement time for oxygen in the Earth's atmosphere is some
8000 years due to animal breathing and plants producing oxygen.

Mars has no magnetic field and relatively weak gravity. Could you
even add oxygen as fast as it would be lost? And once you got
enough oxygen there the atmosphere would still be too thin for a
human to breathe.

"Terraforming" on a planet like Mars is going to have to mean just
digging out underground warrens and pressurizing them with
beathable air.

May as well build colonies beneath the Earth's seas if that is the case. All these numbskull theorists arguing against human space travel for the sake of meaningless convictions yet conjure up fanciful 'terraforming' without first putting the jewels of this planet in context, everything from crystal growth to stellar evolution, cause and effect of our own planet's motion and a single geometry that seems to weave its way through creation.

People stuck in a timekeeping train wreck act like under-developed adults where nothing pleases them so they misuse the imagination instead of using it in a disciplined way. These under-developed adults are into simulation games whether real or imagined and can be best left to their own devices.
