Is it possible to grow crops (粮食) on Mars and the moon? Possibly. Dutch scientists did an experiment (实验) using simulated soil (模拟的土壤) from Mars and the moon. They planted 10 different crops, including tomatoes, radishes (萝卜), spinach (菠菜) and peas (豌豆). The team succeeded in growing most of the crops. The seeds they get from these plants can be used to grow new crops. The only crop to fail was spinach.
