I made a post linking to photos of a cloud on mars and one of the ice caps. and someone I know that really doesn’t care too much about science perked up “what?? ice? clouds on Mars????” . So I started writing out a response. something that would keep it short and informative. I’m not good at that. So.. hopefully you get what I was saying and find it informative
Here it is.
Well it’s not the same but similar to here.
They speculate it’s like dry ice on the mars caps. Not made from h20 but co2.
It sits for a while (the winter season there) in the dark, for a long long time. Not sure how long but long/cold enough to make dry ice basically.
When spring makes it’s way, the co2 ice turns to a gas real fast. Causes tornado like condition by extreme winds. Which leads to a small bit of precipitation. Actual water. H20 clutters and falls, and is sometimes frozen and sometimes rain.
There are a few locations on that planet that if someone was to go there (like the proposed independent trip) and have some source of constant oxygen (indoor green house etc)and controlled breeding to keep populated but not over populated, the planet could sustain life for a good while.
If those people who “make the trip” there, and not kill each other, and could successfully grow enough food indoors and some out doors, the planet could some day (few thousand years from now) contain life of it’s own
at that point i decided I went off track, but want to take it here and put on that same track. Full of my own theories. Thousands of years of theories.
Whoever makes the trip to Mars, needs a method to make concrete and glass or something similar with the material that is already existing on mars. This so we do not use up resources from earth while trying to make Mars resourceful.
Now consider there are greenhouses creating food supplies and oxygen. and occasional weather and a few or at least one select prime spot(s) that host the best conditions (low wind, safe temperatures, etc) for the shelters build on mars. Several trips outside of the structures to gather material, and surely plenty of times ventilating excessive oxygen out (like the pollution at the factories here on earth), there would be an increase of oxygen in the thin atmosphere on mars. This would possibly increase the amount of rainfall. Maybe not any near future making the elements on mars safe, but an increase in water.
Sure there would be likely not be any fossil fuels, but there is plenty of solar energy and wind energy.
Mars would be livable, but in controlled environments, so long as no one gets to aggressive and everyone gets along well enough.
