Early Space Feasts: Freeze Dried Icecreams

Early spaceflights were nerve-wracking. No one knew how zero gravity impacted digestion or what food was safe. Loose crumbs could threaten the mission! John Glenn, the first to eat in space (1962), munched on applesauce, but it wasn't filling. Astronauts lost weight. NASA's challenge: real food in space. They dehydrated, freeze-dried, or heat-treated meals for room-temperature storage as fridges were too power-hungry.

Astronaut ice cream available in the stores is not exactly what astronauts eat in space, but it is a close variant. More importantly, it is a fun and tasty treat that captures the imagination. Below are some Astronaut Icecream readily available

To provide a familiar treat in space, NASA partnered with Whirlpool to tackle a tricky problem: storing ice cream at room temperature.

The key was removing water without melting. Whirlpool's engineers got creative. They super-cooled the ice cream (below -15°C) then used a special vacuum process to gently remove water as ice, keeping the treat frozen throughout.
