This question in from Mrs Freemans Astronomy class in Idaho. Once people are living on Mars, what types of plants will they grow for food?
That is a great question. Scietists are already thinking and preparing for long-term space flight. Cornell University has been doing researchand has already created the first 100 recipes for this type of mission. They know that flights that last longer than a few months will require the crew to become “space farmers” and grow their own food. The freeze-dried food that is currently used on the space shuttle and the space station will take up too much space on a spacecraft for an approximately 3 year mission (best guess to Mars and back). Astronauts will have to grow their food hydorphonically (or without soil) and become “vegetable chefs”. They will most likely be vegetarians for the entire trip, as meat weighs too much to take. The types of foods vary, but they will be looking for foods rich in the right kind of vitamens and nutrients to endure the types of tasks they will be required to do on the trip.
