(P2) Humans could be on Mars by 2030. NASA has tested “Martian gardens”. They used volcanic dust. This is similar to Mars dust. The scientists grew lettuce in it. The lettuce tasted normal, but it had weaker roots and it took longer to grow. NASA said testing ‘Martian gardens’ on Earth would help to grow food on Mars in the future.
