Farming in space: environmental and biophysical concerns

Area of Science:

• Space exploration
• Astrobiology
• Controlled environment agriculture

Background:

• Space colonization necessitates self-sufficient life support systems, including food production.
• Earth-based agriculture faces challenges from global warming, requiring innovative solutions.
• Space agriculture must overcome unique environmental factors like microgravity and resource limitations.

Purpose of the Study:

• To outline the challenges and requirements for establishing plant-based food production systems in space.
• To highlight the need for adapting terrestrial farming practices to extraterrestrial environments.
• To emphasize the role of technological advancements in enabling space agriculture.

Main Methods:

• Analysis of environmental factors in space (gravity, temperature, pressure, atmosphere).
• Identification of challenges in mass transport and boundary layer effects in microgravity.
• Review of resource limitations in space habitats (power, volume, mass).

Main Results:

• Gravity significantly impacts heat and gas exchange between plants and their environment.
• Microgravity poses challenges due to reduced mass transport and altered boundary layers.
• Space farming requires adaptation to extreme conditions and resource constraints.

Conclusions:

• Space agriculture demands innovative solutions for environmental control and resource management.
• Technological advancements in lighting and sensors are crucial for space farming.
• Developments in space agriculture can improve the efficiency and economic feasibility of terrestrial controlled environment systems.
