A sophisticated control system monitors and adjusts all parameters within the greenhouse to maintain optimal growing conditions. This system likely uses sensors to measure temperature, humidity, carbon dioxide levels, and light intensity, feeding this data to actuators that adjust lighting, heating, cooling, and potentially even the humidity levels.

Life Support System Components

The life support system is the heart of the lunar greenhouse. Key components include:

• Atmospheric Control: This system regulates the levels of oxygen, carbon dioxide, and other gases within the greenhouse. It likely involves oxygen generation (possibly through electrolysis of water), carbon dioxide scrubbing (perhaps using chemical filters or biological methods), and precise pressure regulation.
• Water Management: Water is recycled within a closed-loop system, minimizing waste and maximizing efficiency. This involves collecting water vapor from plant transpiration, and potentially even extracting water from lunar regolith through advanced techniques.
• Temperature and Humidity Control: Heating and cooling systems maintain a stable temperature and humidity range suitable for cotton growth. This likely involves sophisticated thermal insulation, heat exchangers, and humidity control mechanisms.
• Radiation Shielding: The greenhouse incorporates shielding to protect plants from harmful solar and cosmic radiation. This might involve specialized materials or a multi-layered design to attenuate radiation levels.
• Lighting System: Artificial lighting systems provide the necessary light spectrum and intensity for plant growth, mimicking the sun’s spectrum as accurately as possible.
