Space Agriculture For Long-Term Space Exploration
Space agriculture is the declared goal of Canadian researchers at the University of Guelph. “Space agriculture is what’s required for long-term space exploration,” Mike Dixon, director of the controlled environment systems research facility at the University of Guelph, said Tuesday during a space conference in Montreal. “We can’t afford to keep shipping water, oxygen and Kraft dinner to the moon indefinitely.”
Dixon and his team are building a five-foot-square sealed chamber built of stainless steel, Teflon and glass. Gloves built into the box lets the team work on plantings without contamination. Since it would take about ten such boxes to feed an astronaut, the Canadian researchers hope to find ways to produce a higher yield with less water, oxygen and atmospheric pressure.
“We want to grow the first plant on the moon. That’s a Canadian space first that we can actually aspire to,” Dixon said in an interview. “Let’s face it, the next worse place after a snowbank in Canada to do controlled-environment plant production has got to be the moon.”Growing food in space would allow crews to embark on longer expeditions to the moon or even the Red Planet. The plants would be grown in a greenhouse that would provide food, potable water and oxygen as well as recycle carbon dioxide and waste.
In response to criticism that the money could be better spent, Dixon said: "The socio-economic spinoffs are enormous. This is the next Canadarm," he said, referring to the Canadian-made mechanical arm used at the space station.
Dixon is presenting the research at a conference in Montreal. The space conference, the 37th Scientific Assembly of the Committee on Space Research, has nearly 2,000 participants from 61 countries and runs until Sunday.
Science fiction fans are well aware of the potential uses for plants in space. Engineer and sf writer George O. Smith created the idea of "Martian sawgrass" to provide oxygen in his 1942 story QRM - Interplanetary.
Gregory Benford thought about lifezones, pod-like greenhouses that could be attached to the exterior of large space ships.
