Canadian Space Agency astronaut David Saint-Jacques works with BioNutrients samples aboard the International Space Station June 10, 2019. BioNutrients is a biology experiment using microorganisms to produce, on demand, nutrients that humans will need during long-duration space missions. Yeast cells have been engineered to produce two essential nutrients, including beta carotene, which gives your Thanksgiving sweet potatoes their color. This turns the yeast cells’ liquid environment from light yellow to the deep orange seen here. While this is still a ways off from helping astronauts make space pies from scratch, it’s a step toward ensuring explorers will have the nutrition they need for trips to Mars and beyond. The technology NASA is developing for future astronauts also could be used by people living in remote areas on Earth. Learn more about the project here: https://www.nasa.gov/ames/bionutrients.
