How Will We Obtain Food When Living In Space

With­out food and humans can’t live, so liv­ing in space requires some unique ways to obtain a food source. Ini­tially, food will be lifted with each launch. Menus will be filled out and lifted for the entire length of the visitor’s stay in space. Many of the menu items will be frozen and con­tained in freezer stor­age as needed. If the vis­i­tor extends his or her stay when liv­ing in space, food can be lifted in sub­se­quent launches.
But how are peo­ple going to be fed when the hotel goes beyond our means of sup­ply? Will liv­ing in space be prac­ti­cal? The answer is to grow our own food in space. There are sev­eral ways to do this and I’ll be dis­cussing the most prac­ti­cal solu­tions for grow­ing food in outer space. Before we look at var­i­ous meth­ods, we have to con­sider the prac­ti­cal­ity of grow­ing in space if we are to live in space.

One, it’s very imprac­ti­cal to be lift­ing large amounts of soil to grow ter­res­trial plants; there­fore, another method of grow­ing food has to be devised. One good solu­tion is grow­ing using Hydro­pon­ics, a method of grow­ing plants using min­eral nutri­ent solu­tions, in water, with­out soil. With hydro­pon­ics, an abun­dant amount of fresh food can be con­tin­u­ally grown and har­vested for con­sump­tion daily.

Another solu­tion is using aero­pon­ics, a tech­nique for grow­ing (cul­ti­vat­ing) plants with­out them being in soil or in hydro­ponic (water) media. The plants are held above a sys­tem that con­stantly, or inter­mit­tently, mists the roots with nutrient-laden water.

Aer­ial plants nor­mally grow in trop­i­cal cli­mates that expe­ri­ence an abun­dance of rain such as in the rain forests of trop­i­cal areas of the world. These plants are not nor­mally used for con­sump­tion; how­ever, with cross or hybrid breed­ing, plants could be grown aero­pon­i­cally with very high nutri­ent value for human con­sump­tion.
The bot­tom line for extended liv­ing in space is we want to grow plants where we can con­sume the whole plant, includ­ing the roots, stock, fruit, and leaves. Tra­di­tion­ally, we just eat the fruit and either com­pose or throw the rest of the plant away; how­ever, research sug­gests that many potent nutri­ents are con­tained in the other parts of the plant that we nor­mally don’t eat.

Addi­tion­ally, many types of plants that uti­lize the stock and root are used for nat­ural heal­ing pur­poses. Also, as plants grow, oxy­gen is gen­er­ated from the leaf of the plant for us to breathe. Whether plants that we grow in space can gen­er­ate enough oxy­gen for us to sur­vive is ques­tion­able at this stage. Nether the less, grow­ing plants is an essen­tial aspect of liv­ing in space for extended peri­ods of time.


  1. Like the dinosaurs, we all die. I spent years con­tribut­ing to the devel­op­ment of a space­ship, com­plete with the plans to get it to space, all the time know­ing that I will die some­day and all I take with me is what I leave behind. Life can now evolve and fly of this nest as called Earth.
