Freeze-Dried Foods
The primary meal option for Apollo astronauts was freeze-dried food. This sophisticated preservation technique removed water while maintaining color, texture, flavor, and nutrients. Astronauts would rehydrate these foods using water from the spacecraft’s fuel cells before consumption.
Common Freeze-Dried Items:
Thermostabilized “Wetpacks”
Introduced on Apollo 8, “wetpacks” were thermally stabilized meals containing food in its natural form with full moisture content. These required no rehydration and could be eaten directly with a spoon, providing astronauts with familiar food textures and flavors.
Common Wetpack Items:
Bite-Sized Cubes
Ready-to-eat, dehydrated bite-sized foods complemented the rehydratable options. These required no preparation and were perfect for quick consumption during busy mission operations.
Common Bite-Sized Items:
Space Beverages
Beverages provided necessary hydration and a welcome break from solid foods. Apollo astronauts consumed their drinks from special containers designed for zero-gravity environments.
Common Beverage Options:
Innovative Packaging
Apollo introduced revolutionary food packaging to address the unique challenges of eating in zero gravity, making meals more manageable and enjoyable for astronauts.

The Evolution of Space Food Before Apollo
Before Apollo astronauts could enjoy relatively normal meals in space, earlier missions featured much more primitive food solutions. The earliest "space foods" during Project Mercury were simple bite-sized cubes eaten with fingers and pureed foods squeezed directly into the mouth from flexible metal tubes resembling toothpaste, according to NASA's technical reports.
These early solutions proved inadequate, as astronauts struggled to maintain proper nutrition and body weight during missions. The cramped quarters and short durations of these pioneering flights meant that food was more of an afterthought than a priority.
Why Apollo Needed Better Food
The Apollo program necessitated significant modifications to space food systems for several critical reasons:
- Nutritional inadequacy: In-flight food consumption has proven inadequate for maintaining nutritional balance
- Physical discomfort: Some crewmembers had experienced nausea and undesirable physiological responses
- Mission duration: Longer mission durations require more substantial and palatable food options
These factors pushed NASA to develop more sophisticated food systems that would not only meet nutritional requirements but also boost morale during the stressful and historic lunar missions.
How Was Food Prepared for the Moon?
The Apollo food system consisted of several distinct categories of food, each with specific preparation methods and packaging solutions designed for the unique challenges of spaceflight.
Freeze-Dehydrated Foods: A Space Innovation
Freeze dehydration emerged as the optimal method for preserving food for the Apollo missions. This sophisticated technique preserved remarkable quality in the final product, with color, texture, flavor, nutrient content, and reconstitution properties closely approximating the original food.
The freeze-drying process worked through several precise steps:
- Rapidly freezing food in circulating air at approximately -40°C
- Placing frozen food in a vacuum chamber with pressure reduced to less than 2 mm Hg
- Applying controlled heat (25-30°C) to sublimate ice directly to vapor
- Removing water until the food reached approximately 2% moisture content
These dehydrated foods require rehydration before consumption. Fortunately, the Apollo Command Module provided both hot and cold water as a byproduct of fuel cell operation, where hydrogen combined with oxygen to produce electrical energy and water. This capability greatly improved food palatability compared to earlier missions.
Thermostabilized "Wetpacks": A Major Advancement
The Apollo 8 mission introduced an important innovation in space food: the "wetpack." These thermally stabilized meal items contained food in its natural form with full moisture content, requiring no rehydration, and were eaten with a spoon. The development of retort pouches for these thermostabilized foods represented a significant advancement in the Apollo food system, as detailed in NASA's technical reports.
Examples of wetpack foods included beef stew and turkey and gravy, providing astronauts with more familiar food textures and flavors. These items were particularly popular among the crews, offering a taste of home during their historic journeys.
Natural Form and Bite-Sized Cubes
Ready-to-eat, dehydrated bite-sized foods complemented the rehydratable options in the Apollo food system. These included items like:
- Bacon squares
- Cinnamon-toasted bread cubes
- Sugar cookie cubes
- Peanut cubes
- Date fruit cake
These foods allowed for quick, convenient consumption without preparation time, perfect for busy astronauts managing complex mission tasks.
The Apollo Menu: What Was Actually Eaten?
Apollo astronauts enjoyed a surprisingly varied menu during their missions. The food system for Apollo 11-16 featured specific meal rotations carefully planned to provide adequate nutrition while maintaining crew satisfaction.
Typical Command Module Meals
A Command Module food locker contained forty-two man-meals (starting with day 1, meal B), an oral hygiene kit, and spoons. Typical menu items included:
For Breakfast:
- Peaches (rehydratable)
- Bacon squares
- Strawberry cubes
- Grape drink
- Fruit cocktail
For Lunch/Dinner:
- Sausage patties
- Beef stew (wetpack)
- Chicken and gravy (rehydratable)
- Spaghetti with meat sauce (rehydratable)
- Potato soup (rehydratable)
- Cheese sandwiches (dry bite)
- Pineapple fruitcake
For Dessert:
- Butterscotch pudding (rehydratable)
- Banana pudding (rehydratable)
- Chocolate pudding (rehydratable)
- Apricot cereal cubes
This variety helped ensure astronauts received proper nutrition while also preventing menu fatigue during their missions.
Lunar Module Meals
The Lunar Module had its own specialized food provisions. While on the lunar surface, astronauts consumed meals like:
- Bacon squares
- Peaches (rehydratable)
- Sugar cookie cubes
- Coffee
- Beef stew (rehydratable)
- Cream of chicken soup
- Date fruit cake
These meals needed to be particularly easy to prepare and consume, as astronauts on the lunar surface had limited time and facilities for food preparation.

| Breakfast | Peaches (rehydratable) Bacon squares Strawberry cubes Grape drink Fruit cocktail | Bacon squares Peaches (rehydratable) Sugar cookie cubes Coffee |
| Lunch/Dinner | Sausage patties Beef stew (wetpack) Chicken and gravy (rehydratable) Spaghetti with meat sauce Potato soup Cheese sandwiches | Beef stew (rehydratable) Cream of chicken soup Date fruit cake |
| Desserts | Butterscotch pudding Banana pudding Chocolate pudding Apricot cereal cubes | Sugar cookie cubes Date fruit cake |
Drinking in Zero-G: Beverage Solutions
Beverages formed an important part of the Apollo astronauts' diet, providing necessary hydration and a welcome break from solid foods. The beverage selection included:
- Orange drink
- Orange-grapefruit drink
- Pineapple-grapefruit drink
- Grape punch
- Coffee
Unlike the plastic drinking bags used on later Space Shuttle missions, Apollo beverages were rehydrated and consumed using special containers designed for zero-gravity environments, as documented by researchers.
Water for rehydration came from the spacecraft's fuel cells, making it possible to save significant weight by sending up dried beverages for rehydration in space. This clever solution addressed one of the fundamental challenges of spaceflight: the high cost of launching weight into orbit.
Packaging and Eating Without Gravity
The Apollo program introduced significant innovations in food packaging to address the unique challenges of eating in zero gravity.
Spoon-Bowl Package: A Revolutionary Design
A major advancement for Apollo was the "spoon-bowl" package for rehydratable foods. This injection-molded, high-density polyethylene base with a thermoformed flexible lid made of plastic film allowed astronauts to add water through a septum in the base using a hollow needle. The design provided a container from which astronauts could eat with a spoon—a significant improvement over squeezing food from tubes.

Color-Coded Organization
To keep food packets from floating away in the microgravity environment, the packets used color-coded Velcro: Red for Commander, White for Command Module Pilot, and Blue for Lunar Module Pilot. This simple but effective system helped maintain order during meal times and prevented confusion among crew members.
Eating Process
While earlier missions required astronauts to squeeze food directly into their mouths, Apollo astronauts could use utensils (spoons) to eat more naturally. Food requiring heating could be warmed, though not to the same degree as later missions like Skylab that featured proper ovens.
This advancement represented a significant step toward normalizing the experience of eating in space, which contributed to astronaut morale and nutrition.
| Food Category | Preparation Method | Packaging Type | Examples |
| Freeze-Dried | Required water injection and reconstitution | Spoon-bowl package with injection port | Peaches, chicken and gravy, spaghetti, puddings |
| Wetpack | Ready-to-eat, no preparation needed | Thermostabilized retort pouches | Beef stew, turkey and gravy |
| Bite-Sized | Ready-to-eat, no preparation needed | Individual wrappers with Velcro backing | Bacon squares, cookie cubes, fruit cake |
| Beverages | Required water reconstitution | Special zero-G containers | Coffee, orange drink, grape punch |
Planning the Perfect Space Meal
The development of Apollo menus required careful consideration of numerous factors, from nutritional content to crew preferences and operational constraints.
Menu Selection Process
Apollo astronauts selected their menus months before flight during their training period. Personal preferences were taken into account to ensure crew satisfaction, with each astronaut having some choice in their daily meals.
For example, the Apollo 11 crew selected specific menus for their post-mission quarantine period in the Lunar Receiving Laboratory, featuring items from Stouffer Foods, which specialized in frozen meals. During quarantine, they enjoyed conventional meals including options like eggs, bacon, toast, and assorted pastries—a welcome change from space food, according to historical documents from the Space Centre.
