Growing Plants In Lunar Gravity

smooth wombat writes "If everything goes according to plan, an experiment designed to test whether plants can grow in the limited lunar gravity will hitch a ride with a competitor for the Google Lunar X Prize. 'The current prototype for the greenhouse is a 15-inch-high (37.5-centimeter-high) reinforced glass cylinder that's about 7 inches (18 centimeters) wide on the bottom. Seeds for a rapid-cycle type of Brassica plant — basically, mustard seeds — would be planted in Earth soil within the container.' The press release from Paragon Space Development Corporation outlines its partnership with Odyssey Moon to be the first to grow a plant on another world. In addition to the experiment, Paragon will be helping Odyssey with the thermal control system and lander design. To win the prize, Odyssey must land its craft on the lunar surface by the end of 2014."

Re:Lunar sunshine and lunar soil

The biggest problem with the soil is that it's sharp. There's no weathering on the moon; the "soil" is dust and grit with very sharp points and edges. The plants would be enduring constant irritation and injury.

Of course, you could sift the dust through a concentrated beam of sunlight and melt it into little spheroids. That would still be cheaper than grinding or importing something softer. The point is, you'd have to process your lunar resource of choice somehow; you can't use it "straight up."
