Space agriculture, also known as astro-agriculture or space farming, is the practice of growing plants and food crops in outer space. This area of research focuses on developing sustainable and efficient methods for producing food in the hostile environment of space. Space agriculture is essential for long-term space missions, such as those to Mars or beyond, where astronauts will need to have access to fresh food for nutrition and psychological well-being. Researchers in this field study various techniques, such as hydroponics, aeroponics, and bioregenerative life support systems, to grow crops in controlled environments with limited resources such as water, light, and space. Overall, space agriculture aims to provide a reliable and sustainable source of food for astronauts during extended space missions.
