Yes, we’re all familiar with astronaut ice cream, but freeze-dried food is an incredibly important innovation from NASA. Developed with Nestle in the 30s to aid space exploration, NASA began the process of freeze-drying food, which helps food retain 98% of its nutritional value while making it easy to transport and store for an average of 25 to 30 years. These benefits combine to provide a great solution for soldiers, hikers, survivalists, and those preparing for natural disasters.
