Astronaut Ice Cream
Enjoy your ice cream just like the astronauts do - the freeze-dried way! The Astronaut Ice Cream and other freeze-dried food items have been aboard space missions since the early days of Mercury Missions. They continue to be used on NASA missions today.
How is the Astronaut Ice Cream Freeze-Dried?
Freeze-drying or lyophilization removes water from the ice cream by lowering the air pressure to the point where ice shifts from a solid to gas.
The ice cream is placed in a vacuum chamber and frozen until the water crystallizes. The air pressure is lowered, creating a vacuum, forcing air out of the chamber. Then heat is applied, vaporizing the ice, and finally a freezing coil traps the vaporized water.
This process continues for hours, resulting in a perfect freeze-dried ice cream slice.
