Scientists have come up with many ideas for growing food in outer space. One concerns growing plants directly in water (called hydroponics), for instance, and another is growing them using misted nutrients from the air (called aeroponics). But both of these options are expensive, so some scientists are also exploring a more traditional method of feeding future astronauts — growing crops directly in lunar and Martian soil.
