Freeze-drying is a technology of preserving food by removing moisture while keeping its nutrients, flavour, and texture intact. The process involves freezing the food and then placing it in a vacuum, where the ice turns directly into vapour through sublimation. This leaves behind lightweight, long-lasting food that’s easy to store and rehydrate when needed.

How NASA Uses Freeze-Drying Technology in Space Missions

NASA was among the first to use freeze-dried food for space missions. With limited storage space and no refrigeration on board, astronauts needed meals that were lightweight, compact, and long-lasting. Freeze-dried food became the ideal solution, providing them with nutritious and tasty meals throughout their journeys.

Why Freeze-Dried Food Works in Space

• Extended shelf life: Freeze-dried food can last for years without getting spoiled.
• Lightweight: With the water removed, the food becomes much lighter—critical for space travel.
• Retains nutrients and flavour: Despite being dried, the food maintains its original taste and nutritional value.
• Easy to prepare: Astronauts only need to add water to quickly rehydrate their meals, making it convenient to eat in zero gravity.
