Space food – vegetables grown on Mars – is in the realm of possibility, an experiment by Dutch scientists has proven. Radishes, peas, rye and tomatoes are capable of thriving in the Red Planet's soil without soaking up heavy metals that would be harmful to humans. Other vegetables are likely to draw up quantities of copper, lead and cadmium identified in Martian soil and unsuitable for human consumption. The experiments have been conducted by Wageningen University in the Netherlands, and so far they have successfully raised 10 crops in soil with a similar composition to that found on Mars.
