Martian colonies of the future will require vast quantities of food, but bringing an endless stream of foodstuffs from Earth would be costly and dangerous. The best answer to this conundrum is to grow food in greenhouse, specially constructed for that purpose. However, such a system would likely require large quantities of topsoil as a growing medium for the plants (water to supply a hydroponic system would probably be in short supply). University of Georgia (UGA) researchers developed a series of artificial soil mixtures mimicking the topsoil of Mars. These substitute samples of Martian regolith were composed of mixtures of…
