Nuclear Reactor Options for Mars Rescue Mission
| Reactor Type | Power Output (kWe) | Fuel Type | Key Safety Features | Development Status | Suitability for Rescue Mission |
|---|---|---|---|---|---|
| Radioisotope Thermoelectric Generator (RTG) | ~0.11 | Plutonium-238 | Simple, no moving parts | Operational on Mars | Insufficient power for primary mission needs |
| Kilopower Heat Pipe Reactor | 1-10 (scalable) | Enriched Uranium-235 | Inherently safe, passive heat removal, self-regulating | Prototype tested successfully (KRUSTY) | Strong candidate due to scalability and demonstrated technology |
| Fission Surface Power (FSP) | ≥ 40 | Low-Enriched Uranium | Robust, reliable for crew safety | Under development, lunar demonstration planned | Excellent candidate for high power demands |
| SAFE-400 | 100 | Uranium Nitride | No positive void reactivity coefficient | Development in early 2000s, less recent research | Potentially high power, but development status less certain |
| Uranium Molten Salt Reactor (UMSR) | Conceptual | Uranium-233 (from Th-232) | Reduced weight, efficient heat transfer | Conceptual | Not a near-term solution due to conceptual nature and fuel source |
Colony Dashboard
To manage efficiently manage, maintain and grow the different components of a Mars colony we developed a dashboard that provides an overview over the state of all systems relevant to the inhabitant's survival. Key metrics such as energy consumption and production, current irradiation values and greenhouse temperature can me instantly monitored and controlled. This allows for fast response in case of hazardous situations and malfunctions.

Landing Position and water availability
The Landing position based on the stranded Aristronaut's position will determine the water availability and temperature around the settlement. If stranded at one of Mars' poles, the Aristraunaut will be able to take advantage of abundant water ice. Accessing this water is essential for both life support and potential propellant production. Several technologies can be employed for water ice extraction.
