Resumen

The Aurora 91 Mars analog mission investigated the response of edible plants to ionizing radiation and electromagnetic fields (EMFs) in a simulated Martian greenhouse. Within a closed habitat, species such as daikon radish, lentils, microgreens, arugula, and leek were grown under controlled lighting, substrate, and hydration. Background radiation averaged 0.13-0.15 μSv/h, while localized EMFs reached up to 1900 V/m and 19.9 μT. Results showed species-specific outcomes: lentils reached 10 cm in height, while radish had 87.5% mortality and fungal growth. Microgreens exposed to magnetic fields germinated faster and showed root alignment consistent with magnetotropism. Arugula and leek did not germinate, suggesting higher environmental sensitivity. Despite low radiation levels, stem fragility and mold were observed, indicating cumulative stress. The study highlights the dual role of EMFs as both environmental stressors and bio-stimulants, supporting their integration in Martian plant growth modules to enhance early-stage resilience and orientation under extreme extraterrestrial conditions.
