Restarting Mars

Here's an idea for you

We drill to Mars' core, and add/pour in the minerals/metals that would help give Mars an electromagnetic field.

Instead of mining ore, we'd be depositing ore, resourced from other parts of the planet, or from an asteroid rich in the materials needed to complete the project.

Then with it's phosphorus-rich soil, Hemp would be a perfect terraforming plant, to get the industries going as well.

3D printed hemp polymers, layered with fibers and fiber-molding, we can make materials that are stronger than steel and lighter than steel.

We can then make return vehicles to Earth, with Mars grown hemp.

We can get there with Earth grown hemp, with hemp-based massive-spacecraft panels and cranes to assemble, and the hemp based fuels needed to propel, hemp-based fiber/polymers, hemp-carbon products, hemp-graphene products such as batteries and composite-materials.

We can also use green/blue algae grown around the areas outside that are near moisture, they can help start forming oxygen rich layers to our new Mars electromagnetic-field potential.

For hemp, build massive geodesic-greenhouses, fill them with hemp, and when Mars is at 50%-60% of the atmospheric needs, we slowly open up the hemp-greenhouses, first over-night, then when the sun hits the gasses, they'll expand, and help push layers of gasses into the various electro-field layers.

Continuing to do that, pumping the atmosphere overnight, until people could cut back to just using oxygen, not have to use a space-suit, then we can plant hemp outside of the greenhouses besides the algae.

No-till method, so that we capture more soil-bacteria gasses that can be released by the plants, when needed.

Hügelkultur methods. We use anything that we find that is organic, and we bury it in mound-compost lines, creating more and more organic-gas production and nutrient-rich soil, that will help us grow hemp there on those Hügelkultur mounds.

We should run some tests underground and grow most of our food underground, right away, where we can live, until we terraform the surface.

We can make geodesic domes to view the sun/outside.
