Know about Space Agriculture Industry


Space farming refers to growing food crops and other materials in space or on celestial objects outside of Earth, equivalent to farming on Earth. Agriculture on celestial bodies, like the Moon or Mars, shares many similarities with agriculture on a space station or space colony. But, depending on the size of the celestial body, it may lack the microgravity complexity found in the latter. Each environment would have differences in the availability of inputs for the space agriculture process: inorganic material necessary for plant growth, soil environment, insolation, relative availability of carbon dioxide, nitrogen and oxygen, etc.

Supplying food to space stations and other long-duration missions is heavy and staggeringly expensive. An astronaut on the International Space Station needs approximately "1.8 kilograms of food and packaging per day." For a long-term mission, such as a four-man crew, a three-year Martian mission, this number can grow to 24,000 pounds (or about 10,886 kg).

Due to the cost of resupply and the impracticality of resupplying interplanetary missions, the prospect of growing food in flight is incredibly attractive. The existence of a space farm would help create a sustainable environment, as plants can be used to recycle wastewater, generate oxygen, continuously purify the air, and recycle feces on the space station or spacecraft. Just 10 m² of crops produce 25% of a person's daily needs, or around 180-210 grams of oxygen. This essentially allows the space farm to turn the spacecraft into an artificial ecosystem with hydrological cycling and nutrient recycling.
