University of Arizona scientists have figured out how to grow food on Mars, including sweet potatoes and strawberries.
The project, a NASA Steckler Space Grant collaboration, brings together some 20 researchers from different disciplines to grow crops that could grow on Mars and the moon, all inside of one big aluminum-framed, plastic-covered cylinder.
The result: nearly 100 percent harvestable, top-quality product.
And because all materials are known and controlled, consumers of the food don’t have to worry about unexpected disease or food-borne illness pathogens — which is good news for earthlings and Martians.
