Patience, my brother.
In the meantime -- I have been thinking quite a bit about how to solve Mars. The answer is Algae. If we can grow large quantities of algae on Mars, and harvest algae oil, this would enable entire industries to pop up.
1. Algae provides combustible fuel in the form of refined algae oil. Batteries and solar equipment are unreliable in the Martian climate. Algae oil fuels would enable reliable, high-output power generation at the Martian surface. The emissions of these power plants would only be a net positive to change the composition of the atmosphere.
Algae fuel can also be used for smelting. As the Martian surface is extremely rich in iron, smelting with a fuel source becomes a trivial task. Carbon can be sourced by burning the waste generated in the algae oil production process. By enabling the production of steel, you can produce everything from new (simple) robots to permanent structures in preparation of human civilization
2. Algae oil can be converted into plastics, enabling small part fabrication to repair existing equipment or even manufacture new tools to expand on current functionality.
3. Algae at a mass scale will produce oxygen, slowly transforming the atmosphere from a high amount of carbon dioxide to levels of oxygen conducive to human life. Algae is also extremely resilient to a wide range of temperatures and varying light conditions, making it the perfect crop.
4. Algae crops can be used for food production, either by itself or in conjunction with animals that feed on it (i.e. fish and shrimp)
Of course, there are lots of engineering hurdles to tackle with this i.e. freezing, nitrogen content, and sourcing enough water for such a plan to be viable, but nevertheless algae could present a great opportunity to build our terraformed Mars colony before we even step foot on the planet. No nukes that will make the planet uninhabitable for eons, and no glass domes that will kill everyone inside if they get broken.
