Daily dietary requirements for astronauts, developed by NASA, and a special mathematical model to select the ingredients for the "space salad".The ready-made recipe consists only of products that are easy to produce in the limited conditions of the spacecraft and at the same time containall the nutrients you need. 

The scientists analyzed more than a hundred different plants, and the key task was to find those that combinedFirstly, the researchers chose those plants that containA large number of calories and nutrients in a small amount. 

The second criterion for selection in the space saladit was possible to grow this plant in the conditions of the ship. Selected plants must be able to grow using systems available on the ship, such as hydroponics. In addition, they should take up as little floor space as possible and use as little fertilizer as possible to keep payload to a minimum.
