<p>Hi all, hope you're having a good holiday season.</p><p>So i've got this crazy idea to nuke the red planet, Mars.&nbsp; I am wondering what the community at space.com thinks of this idea?&nbsp;&nbsp;Something i'd want to observe is the average temperature of the planet, is there an increase or a decrease?&nbsp; If the the&nbsp;planets average core temperature increases, is it enough to melt the frozen ice&nbsp;under the martian surface revealing lakes and rivers, is it enough to&nbsp;melt the ice at the&nbsp;poles creating oceans on the Mars surface?&nbsp; If the planet's average core temperature decreases&nbsp;would the planet experience an ice age, if so how much of the planet becomes covered in ice?&nbsp; I believe for life to begin evolving on Mars naturally, liquid water needs to be present.&nbsp; The problem with Mars is that it currently resides outside of the "habitable zone" where water can sustain liquid form.&nbsp;&nbsp;Which means it could be 100's of millions of years before&nbsp;Mars naturally enters the "habitable zone."&nbsp; Why&nbsp;not attempt to kick start evolution by&nbsp;blasting the red planet with a&nbsp;nuclear missile?</p>

<p>Any material vaporized in the explosion will just&nbsp;condense after it has cooled.&nbsp;&nbsp; Unless you had a massive strike, as in complete planetary bombardment sustained over a long period of time.&nbsp; Even then I doubt any carbon, water vapor and other material released from the regolith will be sufficient in quantity to provide a green house type atmosphere.&nbsp;&nbsp; </p><p>The cost of such an endeavor would also be unfeasible.&nbsp; </p><p>&nbsp;</p><p>&nbsp;</p> <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">I don't think I'm alone when I say, "I hope more planets fall under the ruthless domination of Earth!"</font></strong></p><p><font color="#0000ff">SDC Boards: Power by PLuck - Ph**king Luck</font></p> </div>

<p>Kim Stanley Robinson in his 'Mars' series proposed the controlled diversion and impact of a great many icy asteriods/comets to hit Mars over about a two hundred year period, combined with a program of plants genetically engineered (more or less) to release Oxygen into the atmosphere.&nbsp; I seem to remember some folks on another site a long time ago running through the numbers on this; they seemed to think it would work: assuming you had the patience to&nbsp;keep it up&nbsp;two or three hundred years.</p><p>Mars, from what I've read, actually sits&nbsp;just barely inside the outer edge of the Suns 'habitable zone', and also just barely makes the grade (has enough mass) to retain a breathable atmosphere.&nbsp; What it lacks, if I remember right, is a magnetic field.&nbsp; Don't know how to get around that one; maybe set off a bunch of nukes&nbsp;under the mantle???&nbsp;</p><p>&nbsp;</p>

Terraforming Mars is a subject very dear to my heart.&nbsp; Many top scientists have studied the subject and there is a consensus among a group of PHD's that have studied this subject that it could be done.&nbsp; It is true that mars lacks a Magnetosphere and that any atmosphere would slowly get stripped away by the solar wind.&nbsp; But that process is amazingly slow.&nbsp; MAJOR LOSS OF NEW ATMOSPHERE MAY TAKE CENTURIES TO OCCUR.&nbsp; The problem is just making the atmosphere.&nbsp; There is reason to believe that simply installing factories whose sole purpose is the production of CFC's or other greenhouse chemicals may be sufficient to bring the surface temperature to the point where the dry ice that makes up most of the Martian polar ice would sublimate.&nbsp; The CO2 released at that point would start a runaway effect that could raise the pressure at the surface to as much as twice earth sea level.&nbsp; this would drive the temperature well above 0 centigrade allowing liquid water.&nbsp; All this could be done in less than two centuries.&nbsp; Furthermore It is something we need to do, that we are destined to do.&nbsp; It is something that god and nature says we have to do. <div class="Discussion_UserSignature"> <p align="center"><font size="4" color="#0000ff">Buy My Book "The Purpose of Man"</font></p><p align="center"><font size="4" color="#0000ff"><strong>www.thepurposeofman.com</strong></font></p> </div>

<p>A nuke wouldn't be enough by a long shot. A chixilub sized impact into an area with lots of underground ice could create hydrothermal systems and crater lakes that would stay liquid for tens of thousands of years though. If your interest was seeding life rather than terraforming that could be one way to go. Plus you'd get to observe a large impact on a terrestrial planet with an atmosphere, which would be very informative.&nbsp;</p><p>&nbsp;Another way to get liquid water would be to mix the perchlorate salts in the soils near the north pole with the ice sitting beneath it.</p><p>I'm not convinced about terraforming even if the technical hurdles could be overcome. Personally I find the idea of creating a uniquely martian environment more appealing.</p>

<p>Occam's razor, people. Occam's razor.</p><p>Trapping sunlight heat -> aerosols, life, artificial water tables with floors painted black.</p><p>Managing radiation -> More kilometers of atmosphere (you get that with the lower gravity if you keep 1 atm at the surface, look at Titan), a vegetable cover, shielded buildings, rad-resistant species (you don't need to shield the whole planet!), shorter shifts outside of the city.</p><p>Water -> There's lots of it there. And you don't want to create natural bodies of water that get salty, that's a waste.</p><p>Atmospheric loss -> A warmed martian crust is going to release tons of gas at first, and then life is going to digest some more. Balancing the atmospheric composition would be a bigger worry (if we could get a real atmosphere to start with). </p> <div class="Discussion_UserSignature"> </div>
