The first humans to live on Mars might not identify as astronauts, but farmers. To establish a sustainable settlement on Earth's solar system neighbor, space travelers will have to learn how to grow food on Mars — a job that could turn out to be one of the most vital, challenging and labor-intensive tasks at hand, experts say.
"One of the things that every gardener on the planet will know is producing food is hard — it is a non-trivial thing," Penelope Boston, director of the Cave and Karst Studies program at New Mexico Institute of Mining and Technology, said yesterday (May 7) at the Humans 2 Mars Summit here at George Washington University. "Up until several hundred years ago it occupied most of us for most of the time."
Early Mars colonists may have to revert to this mode of life to ensure their own survival, she suggested.
