In the Apollo moon program of the late 1960s, the quality and variety of space food was greatly improved. Hot water was available for rapid reconstitution of freeze-dried foods, and the taste of the foods was much better. The astronauts carried “spoon bowls,” pressurized plastic containers that could be opened with a plastic zipper and the contents eaten with a spoon. Because it had a high moisture content, the food clung to the spoon, making eating seem closer to the earthbound experience.
