Terraforming Mars by Squirrel719

Terraforming Mars is one of the easiest planets to terraform. However it is still pretty hard. This is how I (Squirrel719) would think of it.

Step 1
The first step it to kickstart the geological activity which has almost vanished on Mars, this will melt the solid Iron Outer Core, making convection which creates a Magnetic Field. To do this, a large force is required. First of all, a drill which makes a hole to the center of the planet is created, and then, nuclear detonations are placed in the center of the core. The hole is buried and the nuclear bombs are detonated. This would require a lot of force and preferably a type of nuclear bomb that would create more heat rather than other energy. However, melting the outer core will also restart volcanic eruptions and tectonic movement (not much tectonic movement since Mars has only two plates)

Step 2
The next step is creating a Runaway Greenhouse effect. A way to do this is launch an astroid to the poles which will vapourise the Carbon Dioxide into gas, which will increase the surface pressure slightly as well, This could increase the temperature (combined with step one) up to 30 degrees. Which will make the temperature at the equators above freezing.

Step 3
The third step is further increasing the atmosphere by vacumning up Venus's atmosphere somehow, since Venus has plenty of atmosphere to deplete, this can increase it up from 0.6 kPa to 100 kPa, and of course this will make the rest of the planet much more habitable. However artificial gravity may be required to help sustain it as Mars's magnetic field will only be about a third the size of Earth's.

Step 4
Since Mars has plenty of water underground and some in the poles, the water will simply be pumped to the surface, Adding Hydrogen to the atmosphere (from Jupiter) may be required as well to create enough water for seas.

Step 5
Step 5 is waiting to see if Mars's huge modification is stable. This may take 100 years.

Step 6
The final step is to start adding plants and animals, and done!
