Crops of four vegetables and cereals grown in soil similar to that on Mars have been found safe to eat by Dutch scientists. Mars settlers would have to take their first food supplies with them and then plant crops in order to survive. In the 2015 film The Martian, Matt Damon plays an astronaut stranded on Mars who has to grow potatoes to survive. Some uncertainty remains about which ones might absorb the high levels of heavy metals such cadmium, copper and lead found on Mars. Further tests are needed on the remaining six crops, including potatoes, in research that is being backed by a crowd-funding campaign.

Nasa plans a manned trip to Mars within the coming decades and similar projects are being pursued by the US billionaire Elon Musk and the Dutch company Mars One, tentatively aiming to set up human colonies.
