Space Greenhouses ~ scientists at University of Arizona’s Controlled Environment Agriculture Center who have been experimenting with growing crops hydroponically for a lunar or Martian greenhouse. The greenhouses would be housed in tubes buried under the moon’s surface to protect from radiation in that environment. Water for plant growth could be recycled from base residents’ urine and carbon dioxide could come from the astronauts’ breathing.
