Why a German lab is growing tomatoes in urine
Space tomatoes! "Having developed the technology in the lab, the DLR science team is now taking it into orbit. Later this year, the space agency will launch its Eu:cropis mission (the acronym stands, somewhat tortuously, for Euglena and Combined Regenerative Organic Food Production in Space), a metre-wide cylindrical satellite containing two miniature greenhouses. Launched on a SpaceX Falcon 9 rocket, the satellite will orbit the Earth carrying tomato seeds, a tank of synthetic urine and bacterial colonies. The spacecraft will spin to simulate the gravity of the Moon for the first greenhouse. After six months the spin rate will be increased to simulate Martian gravity when the second greenhouse is brought online."
