Essentially, the space farm turns the spaceship into an artificial ecosystem with a hydrological cycle and nutrient recycling. [4] [5] In addition to maintaining a shelf-life and reducing total mass, the ability to grow food in space would help reduce the vitamin gap in astronaut's diets and provide fresh food with improved taste and texture.
