You can eat vegetables from Mars, say scientists after crop experiment

Dutch researchers successfully raise radishes, peas, rye and tomatoes in soil mixed to match that of the red planet - giving hope that settlers could grow food

Crops of four vegetables and cereals grown in soil similar to that on Mars have been found safe to eat by Dutch scientists.

Radishes, peas, rye and tomatoes grown on dirt mixed on Earth to copy that of the red planet were found to contain "no dangerous levels" of heavy metals, said the team from Wageningen University in the Netherlands.
