Potatoes on Mars?

Potatoes on Mars? Scientists are reporting promising results growing the tuber under conditions that mimic the Red Planet in an experiment in Peru linked to US space agency Nasa.

"Preliminary results are positive," the International Potato Center (CIP) said this week after a potato grew under simulated Mars atmospheric conditions in an experiment in Lima.

The CIP, in a report, said a potato was planted in a specially constructed CubeSat contained environment built by engineers from the University of Engineering and Technology in Lima.

The experiment ran from February 14 to March 5.

"Growing crops under Mars-like conditions is an important phase of this experiment," said Julio Valdivia-Silva, a Peruvian astrobiologist at UTEC in Lima who previously worked at Nasa.

"If the crops can tolerate the extreme conditions that we are exposing them to in our CubeSat, they have a good chance to grow on Mars," he said, adding that several rounds of experiments will be conducted to find out which potato varieties do best.

Potatoes, one of the world's largest food crops, are believed to have first been cultivated by the Inca Indians in Peru around 8,000 to 5,000 BC.

The potential ability of potatoes to grow under such conditions could signal promise for food supplies under climate change and extreme environments.

The custom environment for the Potatoes on Mars project was based upon designs and advice provided by Nasa.

The CIP experiment is set to last five years.
