A BRIEF HISTORY OF FOOD IN SPACEMERCURY PROGRAM FOOD
John Glenn was the first American to eat in space aboard Friendship 7 in 1962. At that time it was not known if ingestion and absorption of nutrients were possible in a state of zero gravity. Glenn's consumption of applesauce, packed in a tube, and xylose sugar tablets with water, demonstrated that people could eat, swallow, and digest food in a weightless environment. Mercury space food of the early 1960s was based on Army survival rations, and consisted of pureed food packed into aluminum tubes and sucked through a straw. While Glenn and the other Mercury astronauts experienced no problems in chewing, drinking, swallowing, or digesting, the food was not considered very delicious.
