In 2006, Japanese and Russian scientists tested how well barley could grow in space. They rocketed barley seeds to the International Space Station and planted them aboard the Zvezda Service Module. After spending five months in orbit, the fourth-generation of barley was brought back to earth, where Japanese brewer Sapporo fermented it into the world's first space beer. A six-pack costs $110—not bad, considering it was imported from the cosmos.
