This thread is spun off of a previous thread, but I am unhappy with that thread's restrictions to simply the plant growing capabilties on Mars.
The original thread for reference:
"confirm that there are days that blue light gets through - clearer days. And I would think that as the environment is effected, this would began to
change - moisture beginning to cleanse the atmosphere of the dust. "
Moisture can not exist in anything but a "vapor" form under such reduced pressures, it wouldn't condence and bring the dust out of the
"but what I am also finding is just the opposite of what is concerning you...that there will be too much radiation for the plants - versus not enough
in the form of needed light. I really can't find any writings that think the light available will be a problem, but I'm finding a few on the lack of
protection from radiation."
Correct, radiation is a problem, but that is in the gamma and x-ray and even cosmic radiation range.
What is discussed here is the visible range only, which is never discussed by Terraformers because frankly they are morons.
They piece together some good stuff, but stop when what shatters their hopes is present.
After-all, they think an ozone layer will save them, well funny, without our magnetic field we'd all die regardless of our ozone layer.
They don't ever take into the fact that a large reason that Mars's atmosphere is gone, is because it was blown into space by solar winds, because of
a lack of a magnetosphere. Something we can not create on Mars.
They never take into account that Mars's polar caps thaw out most of the CO2 every year, so thawing those caps will not make any noticeable change in
They also never mention the dust storms.
A planet made of nothing but dust...
Increasing the atmospheric pressure would allow those dust storms to actually pick up larger sized particles, breaking off even larger sized pieces of
rocks, inevitably creating the worst dust storms imagineable.
If Mars had an atmosphere even a quarter the thickness it is now the dust storms there would be so devastating that anything we put on the surface
would be chewed to fine grains by the time it was over.
These factors are always left out by would-be terraformers who are propped up by NASA's Public Relations.
So I don't really think their lack of mentioning the problems of solar energy reaching plant-life is a sure indicator it is not a problem.
What I'd like is comparisons...or maybe I should just find some butterscotch wrapping and try some experiments of my own. Putting them in front of a
slightly tinted window to try and reduce enough light so as to be as far away from the Sun as Mars is. See if a plant will grow in that light level
And then see if that plant will grow in a desert as arid as the atacama, in 1/4th ATMs and periodically sand-blast it.
I would try and keep this thread focused, but the number of problems in terraforming Mars are so vast, that I feel I should really start some
reasearch ahead of time to start putting terraformers in their place.
Right now, like the terraforming concept, these are just counter concepts. We of course can't really predict if dust storms would continue to occur
if the atmosphere got thicker, but I see no reason why they would not, where there is dust and thermal convections you get dust storms.
Since the planet's proximity to the Sun changes once in its year, the change in temperatures would be even more dramatic probably making the storm's
wind speed rise from 300 mph to near 500 mph or some un-godly figure.
Considering I've been in a 90mph wind storm, and it lifts good sized rocks off the ground, if we made Mars an atmosphere like earth, those boulders
we see on Mars would become the dust storm's new fuel...we'd have to change names for the Martian Boulder storm.
And that's not bullsheissing either. Tornados throw cows sometimes miles away.
Tornados are 300 mph winds.
Dust storms on Mars are 300mph sometimes, only reason it doesn't blow the rocks like twigs is because the atmosphere is 6 millibars instead of 1100
Again...I am not sure we have much to discuss about the plant growing problem, it is just a conceptual problem I have been thinking of. There are
obviously far worse problems to be thinking about where it concerns Mars.
--------Break--------I have just decided I'm making this the first post of a new thread, because I want to expand the discussion to terraforming Mars
