## Key points

- The research roadmap for assessing the feasibility of warming Mars outlines three promising research tracks:
- Solid-state greenhouse membranes for local warming near human bases
- Orbiting reflectors to warm key sites on Mars
- Strengthening Mars' natural greenhouse effect to warm large regions or the entire globe
- Purpose of the roadmap is to identify conditions, costs, and risks associated with warming Mars, not presuppose its desirability.
- Each approach carries scientific and technical risks that require further research.
- Near-term priorities include testing key parameters on Earth, assessing bioplastic habitat production potential, and designing experiments for implementation on Mars.
- Research aligns with existing efforts to understand Mars' atmosphere, volatile evolution, and hazards to human explorers.
- External uncertainties include fluctuations in launch costs impacting feasibility of warming strategies.
- Relatively modest research investments could extend life beyond Earth as exploration of Mars continues.

## Summary

The research roadmap for assessing the feasibility of warming Mars outlines three promising research tracks to determine whether Mars could be warmed using non-biological methods. The purpose of this roadmap is not to presuppose that warming Mars is desirable, but rather to identify the conditions necessary for Mars to be warmed, the associated costs, and potential risks. The first research track involves solid-state greenhouse membranes that offer local warming near human bases on Mars. This technology could aid in water harvesting, food production, and oxygen supply. The second track explores the use of orbiting reflectors to warm key sites such as bases and CO$_2$-ice reservoirs on Mars. However, a large combined area would be required for this approach to be effective. The third track focuses on strengthening Mars' natural greenhouse effect to potentially warm large regions or even the entire globe, although many details still need to be worked out. Each of these approaches carries scientific and technical risks that must be addressed through further research. Near-term priorities include testing key parameters on Earth to determine the feasibility of engineered aerosol warming, assessing the potential for exponential production of bioplastic habitats, and designing experiments for implementation on Mars. The research proposed in this roadmap aligns closely with existing efforts to understand Mars' atmosphere, volatile evolution, and hazards to human explorers. External uncertainties include fluctuations in launch costs which may impact the feasibility of implementing these warming strategies. In conclusion, relatively modest research investments could keep open the option of extending life beyond Earth as scientific exploration of Mars continues. Key decision points and alternative pathways are discussed in case research outcomes are negative or positive. Overall, this roadmap provides a comprehensive overview of potential methods for warming Mars and highlights the importance of continued research in this area.
