Planning for life on Mars

Over the next few months, my colleagues and I started to explore what we could grow in the material. We found that tomatoes, peas and carrots all took to the soil and grew well. But could these plants realistically survive on Mars?

The planet does have water, but most of it is frozen at its poles or buried deep underground. So for plants to live, water would need to be pumped up to the surface. Mars has almost no atmosphere and no magnetic field, so plants would have to be housed in colonies, with greenhouse-like structures to protect them. In these, an internal ecosystem with a controlled atmosphere could help the plants to retrieve oxygen through hydrolysis.
