The production of a Martian biofuel from CO2 involves four modules: algae cultivation to convert CO2 to glucose, algae processing to release the stored glucose from the algal biomass, fermentation to convert glucose to the desired biofuel and separation of the biofuel for burning in a Mars ascent vehicle (MAV). Other key parts of the process include H2O recycling to maximize the use of limited Martian water and O2 storage to capture excess photosynthetic oxygen for redistribution to other parts of a Martian
