Let us take this moment to possibly think about the glorious gift that Mars is for us, the blank canvas awaiting the brush, the red gem that until now has been just out of arm’s reach. As far as the soil composition goes the red planet is pretty much ready for plant life, I personally believe the only thing you would need to get things going is some time, and proper implementation of microbial life to get things started, as the main problem I would see occurring would be that the soil is “dead,” for now. It has all the basic nutrients you would need for growth, you would, however, have to add in some “fluff” like coconut husk or ever perlite to help disperse the water to the roots and help break down the clay like quality that is the surface. Well, now we’ve figured out some of our potential soil issues, what’s left is dialing in light, atmospheric conditions, temperature, and last but certainly not least gravity.
With the atmospheric conditions being at about 95% carbon dioxide this may seem like a major hurdle to get over, but the implementation of plant life will help to turn that into an oxygen-rich atmosphere as well as eventually lead to the strengthening of the atmosphere against the Sun’s harmful radiation. We just have to help aid the plants with artificial oxygen implementation at night and minor amounts during the day. I imagine the first farming projects will probably be large greenhouses that will probably allow for burping carbon dioxide in and oxygen out in smaller increments at first, which the greenhouses will also help control temperature and allow the use of artificial light supplementation when necessary. So, what about gravity? Well since Mars has much less mass than the earth it has about 38% the surface gravity, meaning a 100-pound person on Earth, would be 38 pounds on Mars. This would allow for plants to grow larger without negative effects during their stretch towards the light. It’s sort of a win-win situation, we help these species spread throughout the galaxy, and in turn, they’ll help the atmospheric conditions become livable for us. We’re opposite sides of the same coin.
As our living conditions change the further out we branch, the more creative we’re going to have to get without farming and cultivation techniques. Just imagine the possibilities, like having huge farming space stations that orbit neutron stars, ever aiding the plants pulling them down towards the light which could also double as a power generating station as well, or deep space guerrilla farming. Where we could manufacture meteorites that would basically work like a seed bomb that we could use to plant new life on planets we may now be able to reach yet. Though space may seem dark from our perspective on earth, the endless possibilities that await us are ever bright.
