Which company developed the freeze-dried ice cream made for NASA’s Apollo missions?

Whirlpool Corporation developed the freeze-dried ice cream made for NASA’s Apollo missions.

Whirlpool worked with NASA during the 1960s to create foods suitable for spaceflight. The company developed a process that froze the ice cream and then removed its water under vacuum. The result was a lightweight, shelf-stable product that could be eaten without refrigeration.

Astronaut ice cream is often associated with Apollo missions and museum gift shops, but it was not a routine staple of the Apollo menu. It was reportedly carried on Apollo 7, while later accounts differ about how frequently astronauts actually ate it. The product’s popularity on Earth grew through science museums and novelty stores.

Freeze-drying is different from simply freezing ice cream. It removes moisture while preserving a porous structure, allowing the food to remain stable for long periods. Space food must also be lightweight, low in crumbs and easy to package in microgravity.
