In a move that takes us one step closer to creating a colony on another planet, scientists have demonstrated that it is possible to grow edible food crops in soil like that found on Mars and the moon.
“A (permanent) human settlement on Mars or the Moon is becoming more realistic,” authors Dr. Wieger Wamelink and colleagues said in their paper. “Several countries and private companies are preparing for this journey. One of the major issues will be ensuring food availability and safety. Food can and will be brought along, but for a permanent stay, production of crops on Mars or the Moon to supplement or even supply the total food demand could be a necessity.”
