Growing potatoes on Mars to save millions of lives

A team of world-class scientists will grow potatoes under Martian conditions in a bid to save millions of lives.

The experiment, led by the International Potato Center (Cip) and Nasa, is a major step towards building a controlled dome on Mars capable of farming the invaluable crop in order to demonstrate that potatoes can be grown in the most inhospitable environments. 

The goal is to raise awareness of the incredible resilience of potatoes, and fund further research and farming in devastated areas across the globe where malnutrition and poverty are rife and climbing.

“How better to learn about climate change than by growing crops on a planet that died two billion years ago?” said Joel Ranck, Cip head of communications. “We need people to understand that if we can grow potatoes in extreme conditions like those on Mars, we can save lives on Earth.”

Currently, famine affects 842 million people around the world. Global warming creates poor soil conditions and increases the prevalence of pests and disease which have the combined effect of limiting harvests globally but particularly in vulnerable areas where poverty, malnutrition and food insecurity already exist.

For years, Peru-based global research and development organization, Cip, has been testing the robustness of potatoes in the most unlikely places.

Beyond the ability to thrive in such challenging conditions, they are also highly nutritious. An excellent source of vitamin C, iron, and zinc, they contain critical micronutrients missing in vulnerable communities globally.

Understanding atmospheric changes on the surface of Mars will help build more dynamic and accurate simulation centers on Earth, providing further research for future manned missions to other planets and moons in our solar system.

“I am excited to put potatoes on Mars and even more so that we can use a simulated Martian terrain so close to the area where potatoes originated.” said Julio E. Valdivia-Silva, Seti Researcher Associate of Nasa, who is leading the project’s science team.

By using soils almost identical to those found on Mars, sourced from the Pampas de La Joya Desert in Peru, the teams will replicate Martian atmospheric conditions in a laboratory and grow potatoes.

The increased levels of carbon dioxide will benefit the crop, whose yield is two to four times that of a regular grain crop under normal Earth conditions. The Martian atmosphere is near 95 per cent carbon dioxide.

“The extraordinary efforts of the team have set the bar for extra-terrestrial farming. The idea of growing food for human colonies in space could be a reality very soon,” said Chris McKay, planetary scientist of the Nasa Ames research center.

Melissa Guzman, Astrobiologist at Nasa Ames, stated: “The image of students building plant growth payloads and communicating virtually from labs in California, Lima, and Dubai is exciting for the future of planetary exploration and astrobiology.”

“We see the science, educational, and humanitarian goals as being intertwined. In the process of working together toward establishing a community on Mars, our students will also be establishing a community on Earth,” she added.
