Space food has come a long way since John Glenn orbited Earth in 1962. He and other members of Project Mercury, the first American human spaceflight program, had to endure unappetizing foods that came in the form of bite-sized cubes, freeze-dried powders, and semi-liquids stuffed in aluminum tubes. Today astronauts can select from an extensive menu of over 70 foods and 20 beverages. The one thing they still can't get? Fresh fruits and vegetables!
