A lunar greenhouse is an area dedicated to growing crops or plants in space, specifically on the moon. This research area involves developing and testing sustainable methods for growing food in controlled environments using limited resources, such as water, soil, and sunlight. The goal of lunar greenhouse research is to provide astronauts with a self-sustaining food source during long-duration missions or future lunar colonization efforts. Scientists and engineers are exploring various techniques, including hydroponics and aeroponics, to optimize plant growth and maximize food production in the challenging conditions of space.
