Mars Potato Cultivation: Analysis, Challenges, Sustainable Scientific Conceptions

Area of Science:

• Astrobiology
• Agronomy
• Plant Physiology

Background:

• Sustainable Martian habitats require autonomous food production.
• Potatoes (Solanum tuberosum L.) are ideal for Martian cultivation due to resilience and nutrition.
• Significant environmental disparities exist between Mars and Earth, posing challenges for plant growth.

Purpose of the Study:

• To develop a conceptual framework for Martian potato cultivation.
• To identify and evaluate challenges posed by Martian conditions.
• To propose a phased roadmap for achieving potato cultivation on Mars.

Main Methods:

• Systematic analysis of Martian environmental conditions versus plant physiology.
• Identification and evaluation of seven key challenges: atmosphere, temperature, water, soil, nutrients, microbiota, radiation/gravity.
• Development of a four-stage roadmap: genotype screening, analog domestication, habitat cultivation module, and extra-habitat potential.

Main Results:

• Seven fundamental challenges to potato cultivation on Mars were identified.
• A phased roadmap with four stages was proposed to overcome these challenges.
• Hypotheses and key performance indicators were defined for each stage.

Conclusions:

• A structured research agenda is presented for extraterrestrial agronomy.
• The proposed framework guides empirical work towards sustainable Martian agriculture.
• This research is crucial for advancing human space exploration and establishing Martian habitats.
