A Martian greenhouse

For nearly eight years, researchers at the University of Arizona have been developing a 'Martian greenhouse' capable of not only feeding astronauts, but also supplying them with vital oxygen.

"It's a small, bio-regenerative life-support system and that's what NASA has, for many years, tasked us to develop," explained co-principal investigator Gene Giacomelli.

The 18-foot-long hydroponic greenhouse is designed as part of a larger habitat that would land on Mars, unfurl autonomously, and begin growing food months in advance of a human mission. So far, the team has had great success in growing nutritious crops like strawberries, basil, sweet potatoes and tomatoes.
