Galactic Farms Grew Food For Study On Space Settlers

Snap peas growing from one of our experimental systems.

Hi SEAS 2015-16: We decided to build 4 small 30 gallon systems (the x-30s); 2 would use fish effluent and 2 would use human urine as a nutrient source.

Ultimately, Johnson and her crew were able to successfully grow peas and chard, although at low production levels. Although the systems were not as productive as they would have been if there were fewer limitations, the crew reported that working together on the project had value in terms of psychological benefits. The psychological effects of the astronaut diet were addressed in depth when the Hi-SEAS crew was interviewed for a recent podcast on Hidden Brain. They reported that much of their time is spent thinking about food because their options are so limited.

Previous research has shown that astronauts often become bored of their limited food choices and then stop eating as much as they need for optimal health. The theory here is that humans are foraging omnivores and we are evolved to desire a certain level of variety that helps to ensure that we consume the diverse set of nutrients we require. For the crew of Hi-SEAS, having the novelty of fresh vegetables, even if only on special occasions, really helped them feel excited about meals during their year of living on preserved astronaut food.
