NASA’s Johnson Space Center develops and tests space-ready recipes at the Space Food Systems Laboratory using equipment like freeze dryers, convection ovens, and vacuum sealers. Each dish undergoes sensory evaluation, astronaut tastings, and dietitian review to ensure nutrition and palatability for months-long missions. Approved meals are produced in batches, stabilized, and packaged for long-term storage, while repackaged off-the-shelf treats help combat flavor fatigue and support crew morale.

How do astronauts eat well while living months in microgravity? The answer lies in a careful, mission-by-mission food development program run at NASA’s Johnson Space Center (JSC) Space Food Systems Laboratory. Scientists create, test, and package meals so they remain safe, nutritious, and as palatable as possible for long-duration stays on the International Space Station (ISS).
Recipe development and lab equipment
Food scientists design recipes specifically for space conditions and use a range of industrial equipment to create and stabilize meals. Common tools include:
- Freeze dryers (for dehydration)
- Convection ovens and steam kettles (for cooking)
- Standing mixers and canners (for consistent batching and preservation)
- Vacuum sealers and specialized packaging systems (for long-term storage)
These processes focus on shelf stability, nutrient retention, and texture while keeping in mind that astronauts’ taste perception can change in microgravity.
Rigorous testing and menu planning
Every new recipe goes through multiple development cycles. A sensory laboratory evaluates aroma, flavor, texture, and acceptability, then astronauts taste and score dishes under controlled conditions. Dietitians translate those scores into balanced menus that meet caloric and nutritional needs for missions lasting six months to a year. The crew provides final feedback before any item is approved for flight.
Production, preservation, and packaging
Once approved, meals are produced in large batches, dehydrated or otherwise stabilized, and packaged into space-safe containers designed to withstand launch, storage, and handling in microgravity. Packaging is often modified from store formats so items are easier to use and less likely to create crumbs or spills on board.
Comfort foods, research, and morale
Nutrition is essential, but so is comfort. Astronauts may bring limited off-the-shelf treats—cookies, candy, dried goods, and beverages—that are repackaged into space-safe containers to combat "flavor fatigue." Historical footnotes underscore this: bacon was among the foods carried on missions in the Apollo era, and more recently, at least a dozen bottles of Bordeaux spent a year aboard the ISS as part of experiments into aging and microgravity’s effects on wine.
Familiar snacks are more than indulgence: they help sustain crew morale on long missions and provide a psychological boost that complements careful nutritional planning.
Bottom line: Feeding astronauts is a blend of food science, sensory testing, nutritional planning, and practical engineering—designed to keep crews healthy, comfortable, and focused while they live and work in space.
