Consider the following tech tree.

  • The rocket can double as a living habitat, if it manages to land in one piece. Martian dirt could be used to re-inforce the walls to protect against radiation.

  • Solar energy with a battery or nuclear could serve as a power source.

  • Water can be extracted from regolith (martian rock) by baking the regolith in a furnace, the water evaporates and can the be re-condensed.

  • Oxygen can be produced through the electrolysis of water. One kilogram of water produces approximately 880 g of O~2~, which is roughly enough for a day per person.

  • Methane can be produced through the Sabatier process, which takes as input H~2~ and CO~2~, and can be used as a rocket fuel and to make bioplastics out of it.

  • Plants are the tricky part. I will create a further post later in the future to give more detailed information about this. The basic gist is that you can create greenhouses if you have the basic ingredients (mostly water).
