A detailed design study for a deployable greenhouse for Mars mission is has been completed. The greenhouse has been designed so that it has a life span of at least 20 years, a leakage rate of no more that 1% of the total volume per day at the target working pressure of 50 kPa and provides at least six crewmembers with approximately twenty five percent of their food supply. Artificial light is provided by high intensity red and blue light emitting diodes, but sunlight is also used by installing small Lexan windows on the rooftop. The greenhouse structure is a rigid IM7/977‐3 graphite/epoxy sandwich structure with a footprint of Radioisotope thermal electric generators are used to produce power for the greenhouse and its subsystems and the plants are grown in nested pockets located on vertical cylinders which allows for a growth area of An aeroponic water and nutrient delivery system is used in order to reduce the greenhouse water usage. Harvesting and planting is achieved through the use of robotics specifically designed for this mission. The greenhouse structure and subsystems have a total weight of less than 10 metric tons. In this paper the design highlights of several of the subsystems of the greenhouse design will be summarized.
