Space. Food.

Here on planet Earth, it was another bountiful day. On billions of acres of farm and forest, trillions of plants went about their humble business of turning sunlight into food, and food into….more food. Taproots stretched in earthy soil, stalks sprouted determined from the ground, leaves broadened, fruits swelled. Billions of times. On planet Earth. Today.

Not so on the red planet. On the surface of Mars — well, I won’t pretend to be an expert here but — we can safely imagine that gases swirled and time sprawled out immemorial. As far as we know, not a single ray of sunlight was turned into chlorophyll and not a single drop of chlorophyll was turned into roots, stalks, leaves, or fruits. Not a single cow grazed and not a single chicken hatched.

Not a problem, you might say, because lucky for us it was another bountiful day on planet Earth. Chances are good that the startling lack of food on our great neighbor planet didn’t even cross your mind today. Unless, of course, you are one of the fortunate few planning the first manned mission to Mars. Then, you have probably been thinking about it a lot.

Today researchers ended a mock space mission, in which they spent several months isolated in a space dome on the big island of Hawaii. Their goal: subsist on freeze-dried, pre-packaged, and shelf-stable for 118 days, creating recipes, tracking moods, and monitoring health status. Because somehow, with all we know, we don’t know what happens to us when we¬†go months without fresh food, let alone years. We’ve never had to know.

Explorers of the New Age will not be able to set forth with a pocket full of seeds or a hunting spear, like those past. They will need to gather their ingenuity, spices, and Spam if they hope to survive. For the first time, we need to figure out what will happen to those who leave Earth’s bounty in the rearview mirror. What an exciting and terrifying proposition.
