What is astronaut ice-cream? It is a freeze-dried ice cream that also known as Space Ice-cream. It is a brick of dehydrated ice cream that is always ready to eat, with no need for refrigeration.
It tasted strange. And, if i am being given an option to choose between this and the real ice-cream, i wouldn't hesitate to choose the latter.
How is Astronaut ice-cream freeze-dried? Freeze-drying, or lyophilization, removes water from the ice-cream by lowering the air pressure to a point where ice shifts air pressure to a point where ice shifts from a solid to a 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, 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-fried ice cream slice.
It was bought from a shop at Science Centre by the name of 'Curiosity'.
