"Launched into Outer Space and Around the Globe In 1996, thanks to two Italian astronauts, Parmigiano Reggiano became the first all-natural raw milk cheese to be launched into outer space. Later Parmigiano Reggiano was adopted as an official space food, valued for the bone-strengthening calcium and other nutrients it contributes to astronauts’ diets."
This is from the official Parmesan site. I had no idea.
