Advances in food systems for space flight.
Food for space has evolved from cubes and tubes to normal Earth-like food consumed with common utensils. U.S. space food systems have traditionally been based upon the water supply. When on-board water was abundant (e.g., Apollo and Shuttle fuel cells produced water) then dehydrated food was used extensively. The International Space Station will have limited water available for food rehydration so there is little advantage for using dehydrated foods. Experience from Skylab and the Russian Mir space station emphasizes that food variety and quality are important elements in the design of food for closed systems. The evolution of space food has accentuated Earth-like foods, which should be a model for closed environment food systems.
