The whole point of learning about Mars is to make use of it.
The earth forum is https://www.physicsforums.com/forumdisplay.php?f=84" way. This here is the astronomy forum.I'm unclear what remediation would mean in the case of Mars. As far as the current climate there being suitable now or ever for terra-species - that looks unlikely to me. The lack of a magnetosphere and lower gravity look to be pretty daunting to the hope of developing the kind of volume of gases an atmosphere would require to build to anywhere near earth's 1000 millibars or so starting as it is at about 6 or 7 millibars today.
The solar wind is a restless wind. A restless wind that yearns to wander ... And so too does the atmosphere on Mars I'd think which is likely resistant to much volumetric increase at this point, even if one were to increase the pressure there temporarily - ignoring for a moment the way in which such a thing might be accomplished in the first place.
In looking at Earth this was evidently a rather long term process building the atmosphere we see today. Here's a link that addresses Earth's atmospheric evolutionary epochs. The time scale is in billions of years.
Like I said before I do appreciate your ambition on behalf of the species in terms of developing worlds away from terra firma as alternative islands of habitability, but I'd say that as responsible stewards of earth's atmosphere today we have a number of pressing problems that need solving in the next few decades and not the kind of time needed to bootstrap Mars even if we if only as a lab experiment.
But cheers anyway
I wouldn't say that's a good reason to spend billions of dollars on a project to send people to Mars, just because you could possibly grow something there. What exactly is able to grow in the soil is still under speculation.
Though the dirt itself seems to be hospitable, Kounaves pointed out that the very top layer at the surface is exposed to high levels of harsh ultraviolet light that is damaging to organic compounds, so that layer of soil may not be able to support life.
The soil in the Alaskan tundras is far more hospitable than where Phoenix is digging now. If farming is that easy, how about we start growing food here in Alaska for the many hungry, starving people that it would help?You might be able to grow asparagus pretty well, but probably not strawberries."
