Can we growing food in outer space?
Another way aside from eating food? :uhh: PF has https://www.physicsforums.com/showthread.php?t=414380" against overly speculative posts.I think the question should be formulated a little bit differently. Will we grow food in outer space some day or when living in space we'll use another way for feeding our bodies?
There are a few serious technical obstacles to growing food without gravity. The main one that I know of is that water does not stay in contact with the roots; the flow of water in a porous medium without gravity to drive the flow is almost totally driven by surface tension and diffusion. This results in the roots drying out as the local water is absorbed. Plants that use nitrogen-fixing bacteria have the additional problem of gas bubbles forming around the root.Can we growing food in outer space?
