Quoted:
I vote we send Hillary first. Don't even need a guidance system, I've played enough Kerbal Space Program that I'm pretty sure I can just eyeball the trajectory. I agree. I have gotten pretty good and eyeballing that trajectory as well. That is one bitch of a game sometimes. |

Quoted:
since mars does not have a molten core that's produces a protective magnetic field, all c02 released into atmosphere will be scrubbed away by the solar wind. so this fails at step 1. but thanks for playing. Can't we just drill down to the middle of Mars and pump in some iron-nickel alloy?

Quoted:
The lack of a magnetic field around Mars makes terraforming a futile effort. Whatever atmosphere you manage to create would be stripped of by the solar wind. In fact, that's what's already happened. But he sourced it with wikipedia, vice.com, and Discover Magazine's blog. It must be correct! |

Word. The scale problem with terraforming mars is huge. Where as floating cities on venus would be a bajillion times easier, for many many many reasons. |

Would never work.
The planet has no real magnetic field therefore the solar winds strip the atmosphere to include O2 and CO2 needed for life as we know it (which is why it lost it's surface water to begin with). The barometric pressures are below those needed to maintain liquid water (it would all boil off like dry ice does here). The only way to live their is in an enclosed ecosystem that can maintain the needed pressures. Biosphere2 proved we have long way to go before we understand everything needed to do that. The concrete surfaces messed with the atmosphere in it, a totally unexpected event. |

Quoted:
If we had those kind of resources we'd be better off by living off-planet. O'Neill cylinders or the like would be more manageable than trying to terraform dead planets. And due to the same factors that caused Mars to become what it is today, the planet would revert to its current freeze dried state in a relatively short time period. |

That would be the first hurdle: create a magnetic field. Once that is done, the rest of it would probably fall into place. |

They could just send all the politicians, lawyers, SJWs, transgender LBGT weirdos there. It'll be a hospitable planet in no time. Either that or a planet with millions of corpses. In either case however, we'd be rid of all the problems. Just pass some laws that say Mars has to be hospitable, because that's the way the universe works. |

The lack of a magnetic field around Mars makes terraforming a futile effort. Whatever atmosphere you manage to create would be stripped of by the solar wind. In fact, that's what's already happened. It takes millions, perhaps 10s to 100s of millions of years for the solar wind to significantly erode the atmosphere. Yes, Mars will not permanently hold any atmosphere you create. But nothing is forever. Even the sun eventually gives out. And certainly in a million years if Mars has lost enough atmosphere to be a problem, I suspect that if we're still around we'll have near god like technology to address that issue. Over the time scales that we are likely to care, atmospheric erosion is a non issue. |

Yeah lol. Do they think Elon Musk hasn't thought of this shit yet? |

That would be the first hurdle: create a magnetic field. Once that is done, the rest of it would probably fall into place. Mars doesn't have a molten iron core with which to generate one. That is why I said create one: an artificial magnetic field. It would take a lot of power, and that is the first big hurdle. However, once such a field is in place, as I said the rest would "fall into place." I don't think a self sustaining molten core is possible. That may have been something that existed a very long time ago, but conditions have changed so that such a thing cannot self sustain anymore even if re-created. |

Over the time scales that we are likely to care, atmospheric erosion is a non issue. We don't know how long it would take to go from habitable to inhabitable. Plus, the lack of a magneto sphere means that all sorts of destructive radiation is going to flood the surface killing all terrestrial life that we know of. Not a good way to start a planet. There are a lot of things you need for earth based life, Mars lacks in every category. |

No it is still an issue, but not because it would be gone as much as it wouldn't protect the water vapor in the air. The water vapor would be converted to oxygen and hydrogen molecules by the solar radiation thus stripping the planet of any water that was released from the thawing ice. You would have to figure out how to protect the water vapor and start the hydrologic cycle. I don't know that it would ever combined back into water without some kind of protection from the solar radiation. I wonder if there is methane gas there. If so, drill wells and vent them to the atmosphere and see what happens in a 1000 years. 
Put all these drilling rigs back to work.
