Extraterrestrial farmers to raise grain without soil?

If humans are to colonize space , how will we manage sustainable agriculture ? Enter the science of aeroponics .

If you were to set about to enkindle a garden utilizing only lunar or Martian dirt , chance are that your precious plants would eitherdie a horrible deathor survive albeit malnourished .

While there are probably elision to this rule ( i.e.asparagus mightbe capable to thrive within Martian dirt ) , the vast absolute majority of tellurian plant will necessitate terrene stain in decree to prosper , which flummox a vast problem for man ( as hoi polloi need to eat off world , let alone find employment ) .

rather of importing tons of terrestrial soil from the homeworld or manufacturinglarge quantities from humans , it ’s probably wiser to raise them without soil thanks to aeroponics .

Growing plants without any dirt may evoke up trope from a Star Trek movie , but it ’s hardly science fiction . Aeroponics , as one soilless polish process is called , grows plant in an air or mist environment with no soil and very little water . scientist have been experiment with the method since the former forties , and aeroponics system have been in consumption on a commercial-grade basis since 1983 .

“ Who says that soil is a precondition for agribusiness ? ” asked Graber . “ There are two major stipulation for USDA , the first being urine and the 2d being works nutrient . Modern agriculture makes extensive usage of ‘ soilless growing metier , ’ which can include many wide-ranging solid substratum . ”

In 1997 , NASA teamed up with AgriHouse and BioServe Space Technologies to contrive an experiment to test a soilless plant life - ontogenesis system on board the Mir Space Station . NASA was peculiarly concerned in this engineering science because of its low water requirement . Using this method to grow plants in distance would cut down the amount of water that needs to be carry during a flight , which in turning decrease the payload . Aeroponically - produce crop also can be a rootage of atomic number 8 and drinking water for distance crews . ( Astrobiology Magazine )

Using aeroponics would not only abridge the overall cost of raise grain , but enable us to constitute “ ego sustaining ” colonies beyond the Jovain lunar reality ( such asCallisto , Ganymedeand Saturn’sTitan ) , but also upon asteroids and Centaurs ( aka elephantine comet like Chiron ) as well .

While aeroponics would not be workable for every fourth dimension of plant useable ( i.e.raising forestswould require tons of soil ) , it would make it easier to steady down upon the human beings that dance around our xanthous Dominicus which would help man quest to stamp down the final frontier .
