A scientific salad for astronauts in deep space
The ingredients were chosen for their nutritional value, as well as how easy they’ll be to grow with the limited room and resources available on a spacecraft.
An international team of scientists have developed a “space salad” that can keep astronauts well-nourished on future missions into deep space.
The salad consists of seven ingredients — soybeans, poppy seeds, barley, kale, peanuts, sunflower seeds, and sweet potatoes, all in carefully measured amounts — that can be grown in small enclosures on a spacecraft and fulfill the nutritional needs of astronauts on long-duration trips.
Researchers from Australia, the U.K., and the U.S. chose the ingredients based on their nutritional value, growth rate, water and space requirements, and the amount of inedible waste produced.
