Part 4/15:
NASA’s pioneering work has led to advanced preservation methods such as freeze-drying, enabling food to be stored safely for years. Food safety protocols like HACCP—which originated with NASA and Pillsbury—are standard worldwide, ensuring space food remains free from contamination. The ISS aims to extend shelf life further, targeting a five-year or longer storage duration to support increasingly distant and prolonged missions.
To improve space nutrition and ease of consumption, scientists like Xulei Wu develop user-friendly preparation techniques. For example, crew members are trained to tear open packages without losing their contents to floating particles, and rehydration is done via syringes to add water—transforming space foods into more familiar textures and flavors.
