Food doesn't get any less local than when it comes from outer space. But that's not a concern for NASA scientists, who are cultivating ways to grow produce inside the International Space Station—and eventually, hopefully, on Mars.
Researchers believe that eating fresh vegetables will be essential for longer expeditions, but no one's sure how microgravity (as in space) will affect food and our bodies and minds.

Orbital Technologies Corp. (ORBITEC) oversees the Veggie Hardware Validation Test (AKA Veg-01), a groundbreaking endeavor that has produced "a collapsible and expandable Veggie unit (which) features a flat-panel light bank that includes red, blue and green LEDs for plant growth and crew observation." In their latest experiment, a group of 44 astronauts had the chance to try space-grown, red romaine lettuce. The results are still being digested.
