NASA plans to grow plants in space to help feed astronauts and to provide psychological benefits for long-term space flight. [7] In 2017, aboard ISS in one plant growth device, the 5th crop of Chinese cabbage (Brassica rapa) from it included an allotment for crew consumption, while the rest was saved for study. [8]
Cabbage growing in a Veggie unit [1]. The Vegetable Production System (Veggie) is a plant growth system developed and used by NASA in space environments. The purpose of Veggie is to provide a self-sufficient and sustainable food source for astronauts as well as a means of recreation and relaxation through therapeutic gardening. [2]
Since the release of the initial 1989 study, titled A study of interior landscape plants for indoor air pollution abatement: An Interim Report, [6] further research has been done including a 1993 paper [7] and 1996 book [8] by B. C. Wolverton, the primary researcher on the original NASA study, that listed additional plants and focused on the removal of specific chemicals.
The researchers said the tomato plants in intercropping may have benefited from their proximity to the pea plants because the latter are good at turning nitrogen from the air, with the help of ...
In the context of human spaceflight, they can be consumed as food and/or provide a refreshing atmosphere. [3] Plants can metabolize carbon dioxide in the air to produce valuable oxygen, and can help control cabin humidity. [4] Growing plants in space may provide a psychological benefit to human spaceflight crews. [4]
To replicate a Blue Zone way of eating, the goal is to focus on whole, minimally processed foods—think of simple, single-ingredient items like oats, beans, nuts, and rice—and avoid processed ...

In addition to maintaining a shelf-life and reducing total mass, the ability to grow food in space would help reduce the vitamin gap in astronaut's diets and provide fresh food with improved taste and texture. Currently, much of the food supplied to astronauts is heat treated or freeze dried. Both of these methods, for the most part, retain the ...
