One of the biggest obstacles to living on another planet is accessing food. How would we eat? To solve this problem, we need to figure out how to grow food on other planets. Researchers at the University of Palermo have been studying soil on other planets. Their results show that it might be possible to grow crops on Venus, Mars, and the moon. They found that the soil on these planets contains many of the same minerals and nutrients as the soil on Earth.
