Maybe. https://phys.org/news/2017-03-nasa-magnetic-shield-mars-atmosphere.html I'll believe it when they can explain exactly how this inflatable structure is supposed to be built. And that doesn't seem to be in line with the previous claim of 5 KW to protect a space station. This is all sounding a bit too Dyson's Sphere for me. Maybe in the extreme future but not for many lifetimes.
https://www.iflscience.com/space/musk-still-wants-to-nuke-mars-for-reasons-not-based-on-science/ --- As previously reported in Nature Astronomy, even if all the carbon dioxide in Mars' poles were to be released it would amount to just 1.5 percent of what’s necessary to create the needed greenhouse effect. ---
Thus do I recommend that rather than Nukes we use a few large Comets and impact on the poles, releasing what was there as well as what the Comet held. We could just use Ceres and go from there.
Still say we need to build a habitat on Antarctica. The closes thing to Mars we have. Could do a lot of testing there but still be close enough to home to diminish the risk to human life. If we can't survive on Earth we may as well forget about Mars.
That's a better idea for Venus, bombarding it with icy comets. If you can get enough water vapor into that atmosphere, it would combine with the sulfur and carbon there, rain it out of the Venusian atmosphere, and then lock it up in minerals. The minor drawback there is that the process would take thousands of years. Mars, the problem isn't just making an atmosphere, it's keeping an atmosphere. That problem has to be addressed first. Ceres is valuable cosmic real estate, so it would be a crime to waste it that way. Ceres is the stepping stone to the outer planets. It has has water ice, rocky areas to build on, and no atmosphere or dust to mess things up.
We would be better off bombardingbthe planet with carbonaceous asteroids, of which apparently there are plenty, and rely on them to produce methane as they track through the atmosphere. Methane has 20 times co2 greenhouse effect
No one on planet earth needs to convince you of this theory. You have absolutely nothing to contribute to the idea, the planning, and the execution if it were to happen.
