Peppers on the moon

At the University of Arizona, they're working on ways to feed people living away from home.  Far away.  Researchers there have designed a greenhouse that they hope could be used to grow plants on the moon or Mars, to contribute to long-term missions there.

Giacomelli said the research also could lead to plant colonization in another traditionally hostile environment -- large urban centers.

"There's great interest in providing locally grown, fresh food in cities, for growing food right where masses of people are living," Giacomelli said. "It's the idea of growing high-quality fresh food that only has to be transported very short distances. There also would be a sense of agriculture returning to the everyday lives of urban dwellers."

"I think that idea is as exciting as establishing plant colonies on the moon."
