Zero gravity farming is rapidly evolving, offering promising solutions for sustainable agriculture in space. Recent research has focused on understanding how plants adapt to microgravity conditions and developing technologies to support their growth. A notable advancement is the development of the Vegetable Production System (Veggie), a plant growth system deployed aboard the International Space Station (ISS). Veggie provides a self-sufficient and sustainable food source for astronauts, allowing them to cultivate crops like lettuce and radishes in space. This system not only supports crew nutrition but also offers therapeutic benefits through gardening activities. en.wikipedia.org
Another significant development is the use of aeroponics in space farming. Aeroponics involves growing plants with their roots suspended in the air and misted with nutrients, eliminating the need for soil. This method has been adapted for space environments, offering several advantages. It reduces the amount of water and nutrients required, which is crucial for space missions where resources are limited. Additionally, aeroponics minimizes the risk of pathogen spread among plants, as the reduced root contact limits disease transmission. en.wikipedia.org
