kickstarting mars terraforming early


Hi there !
OK so, bascially what is preventing us from terraforming is :
-The prospect of identifiying an endogenous life form that may or may not be DNA or RNA based, with left or right chirality ?
Such an exotic life outside earth would prove to be very valuable for research. and destroying it or compromising it in it pristine state would have moral repercussions : indeed who we are to treat exobiology as inferior ? On the same moral grounds, aliens could treat us as mere microbes and wipe us out with intergalactic clorox.
On the other hand, we love our planet earth life, we find it beautiful, it is the result of 3+B. Years of evolution. and we surely would love to have a backup in case SHTF for earth ecosystems.
So what's the plan ?

1- collect, collect, collect samples as diverse as possible and from as diverse locations through micro landers that would have just one purpose : encase samples and isolate from the environment. period.
this would reverse protect from earth contamination, and provide us specimens and preserve native life. (some kind of "reserve" still morally discutable, but a bit less than doing nothing before engineering the planet

2- once it is done, the show starts : send a lot of micro impactors full of NF3 ? (seems like a helluva greenhouse gas with 17000 radiative forcing of CO2 ?
Quite "non hazardous" - once people stop buying 4K screens larger than their field of view, we'll have oversupply, right ?
Now some model would be needed to calclulate the runaway greenhouse effect generated. I suppose you could help me find the latest models for mars atmosphere/permafrost etc...

3- The use of micro impactors with divided failures whould be more secure and safe than one big rocket full of NF3 bursting in our atmosphere, right ?

Peace, and stay safe

NF3? You mean SF6 or CF4, no? NF3 is toxic at 1000 ppm, or 0.1%. Also, NF3 is more reactive than carbon or sulfur fluorides.

If we want to terraform Mars, I propose we get some object from the outer solar system made of ice and nudge it into a near collision with Neptune, catapulting it into the inner solar system. A collision would warm Mars up really quickly, and bring it much-needed nitrogen. Right now, it's unlikely anything could survive on Mars, seeing as though it lacks one of the four most important elements necessary for life on Earth. It's true that organic chemistry is based on a carbon skeleton, but nitrogen is usually where the action is.

Mood: inert even with vigorous stirring.

Seriously, what's the rush?

This would be a centuries long project. It is not going to be saving anyone or anything any time soon. We can afford to wait a few decades while we do our research and homework.

Besides: in terms of practicality and resources, we stand a better chance of terraforming Earth to make it more habitable for a wide range of species. Maybe start with some desert reclamation and see if that does anything positive for us.
