Do you know that it was NASA's R&D that made it practical or is that conjecture? From Institute of Food Technologists (IFT): Freeze-drying was invented by Jacques-Arsene d’Arsonval at the College de France in Paris in 1906. Later, during World War II, it was widely implemented to preserve blood serum. Since then freeze-drying has become one of the most important processes for preservation of heat-sensitive biological materials. During the 1950s, industrial freeze-drying of foods began. Freeze-drying is currently used as a preservation method for foods, pharma-ceuticals, and a wide range of other products. https://www.ift.org/news-and-publications/food-technology-magazine/issues/2018/february/columns/processing-freeze-drying-foods https://www.ift.org/news-and-publications/food-technology-ma...
