Food in space from hydrogen-oxidizing bacteria

The cost of launching food into space is very high. An alternative to make during missions using methods such as artificial light photosynthesis, greenhouse, nonbiological synthesis food, electric bacteria, and hydrogen-oxidizing bacteria (HOB). This study compares prepackaged microalgae, HOB. dominant factor for each its relative mass due high fuel needed launch a payload space. Thus, alternatives were evaluated an equivalent system (ESM) technique developed by the National Aeronautics Space Administration. Three distinct with crew 5 duration 3 years analyzed; including International Station (ISS), Moon, Mars. components ESM considered apparent mass, heat rejection, power, pressurized volume. selected power source all systems was nuclear power. Electricity biomass efficiencies calculated be 18% 4.0% HOB respectively. indicates that growing least expensive alternative. on average 2.8 5.5 less than also relates feeding Earth global agricultural catastrophe. Benefits include recycling wastes CO2 producing O2. Practical would involve variety sources.
