This is what it would be like to eat ice cream with Neil Armstrong. Astronaut ice cream was originally developed for the early Apollo missions, but it's still as delicious today. Frozen to -40 degrees and vacuum-dried in a foil pouch, the ice cream has a 3-year shelf life. The act of freeze-drying it removes the water, leaving you with a unique treat that has an out-of-this-world texture and flavor. Today, astronaut ice cream, tomorrow, walking on the moon.
