"A group of Dartmouth engineering students recently won a challenge from NASA to design a greenhouse for Mars," writes NHPR. "The challenge was laid out by NASA: Create a system to feed four astronauts on a 600-day mission to Mars.

"Of the five teams from around the country that made it to the final stage of the BIG Ideas competition, the team of 8 students from Dartmouth won for their greenhouse called DEMETER. DEMETER stands for Deployable Enclosed Martian Environment for Technology, Eating, and Recreation."
