NASA's Apollo 7 mission included vanilla ice cream on an official menu, a rare treat made possible by freeze-drying to avoid microgravity risks.
NASA's ice cream challenge
NASA faced a unique challenge when considering food for astronauts in space: even a single crumb could damage sensitive equipment or irritate an astronaut's eye in microgravity. This concern influenced decisions about food choices, including the development of a special dessert.Vanilla ice cream for Apollo 7
NASA included freeze-dried vanilla ice cream on the official menu for the Apollo 7 mission in 1968. This dessert was developed with Whirlpool Corporation to be stored at room temperature, eliminating the need for refrigeration in space.The real problem with ice cream
Despite its appealing taste and preservation qualities, the issue with the ice cream was not its flavor or shelf life. Instead, it was the risk of crumbs floating in microgravity, which could pose a danger to both astronauts and instruments.Apollo 7 mission details
Apollo 7 launched on October 11, 1968, with astronauts Wally Schirra, Donn Eisele, and Walt Cunningham. This was the first crewed mission of the Apollo program, aimed at testing the command module before lunar missions.A unique menu entry
In the press kits for Apollo 7, a detail stood out: "vanilla ice cream" was written in all caps on one of the three menus prepared for the crew. This is the only known instance of a frozen dessert appearing on an official NASA menu.Engineering behind the treat
The inclusion of vanilla ice cream was not a random choice. NASA had entered a contract with Whirlpool Corporation, a company better known for home appliances, to develop a way to store ice cream without refrigeration. The goal was to provide astronauts with a sweet treat in the harsh environment of space.
