Astronaut Neapolitan Ice Cream

Freeze-Dried Ready To Eat Space Food™
Enjoy your ice cream just like the Astronauts do - the freeze-dried way! Astronaut Ice Cream®, as well as other freeze-dried items, have been aboard space missions since the early Mercury Missions. They continued to be used on NASA missions today.
Freeze-drying, or lyophilization, removes water from the ice cream by lowering air pressure to a point where ice shifts from a solid to a gas. The ice cream is place in a vacuum chamber and broken until the water crystalizes. The air pressure is lowered, creating a vacuum, forcing air out of the chamber; next heat is applied, vaporizing the ice; finally a freezing coil traps the vaporized water. This process continues for hours, resulting in a perfect freeze-dried ice cream slice.
