NASA gave this package of "M&M's Royal" mint-flavored chocolate candies to the Museum in 1985 for display in a space food exhibit. In addition to meals, astronauts enjoy a variety of snacks during missions in space. Choices include dried fruit, nuts, cookies, crackers, and candy. NASA usually repackages commercial products for spaceflight, as these "M&M's" have been vacuum-sealed in clear plastic. Although this package of candy did not fly in space, it is typical of snacks that have been available on the Shuttle and previous spacecraft.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
