Hungry astronauts grow cosmic beans CNN

Someday explorers living in space for extended periods might not need perishable care packages. They will instead grow their own veggies. Atlantis, besides delivering groceries to the International Space Station, will return home this week with an experimental food crop grown in the station’s science laboratory. NASA hopes its cultivation of the cosmic beans will lead to the development of a miniature food farm unit in space, informally dubbed the “salad machine.”
