Space-grown vegetables: Astronauts chow down on lettuce
Story highlights NASA astronauts sample lettuce grown on International Space Station It's the first time food grown in space is officially on the menu CNN — A special treat is on the menu for NASA astronauts on the International Space Station on Monday – lettuce. “Fresh food grown in the microgravity environment of space officially is on the menu for the first time for NASA astronauts,” NASA said in a statement. The lettuce was grown aeroponically–in an air or mist environment without soil–in the space station’s Veggie plant growth system. Plants grown aeroponically require far less water and fertilizer, don’t need pesticide, are much less prone to disease, and grow up to three times faster than plants grown in soil, NASA said.
