NASA's Gemini program conducted its first manned flight in 1965. In preparation for that launch, NASA began dehydrating food and sealing it in plastic bags. The bags were labeled with instructions on how to rehydrate the food in space using water.
Food items prepared for Gemini astronauts included scrambled eggs, shrimp with cocktail sauce, curried chicken, and raisin rice pudding. Drinks included coffee, grape juice, and milk.
Since weightless astronauts exerted less energy in space, meals contained fewer calories compared to what the astronauts were used to eating on earth. On average, the food consisted of 17% protein, 32% fat, and 51% carbohydrates.
