Potatoes on Mars

I was listening to The Current on CBC Radio on June 13 and caught the back end of a special on the events taking place to celebrate the International Year of the Potato. I listened to the interview with John Reader, author of a book on the history of the potato. What caught my attention was some old research he cited that was done by NASA. NASA assumed they would send people to Mars and they researched ways of feeding this population. They studied all kinds of fruits and vegetables and found that potatoes were the best nutritionally and that when you planted enough potatoes to feed a certain size of group the potato plants would generate enough oxygen to sustain the population and absorb the carbon dioxide that the population exhales.
