This can of salmon is typical of Shuttle-era menu choices. It was returned from the first Shuttle mission, STS-1 (Columbia), in 1981. As there is no onboard refrigerator or freezer, most foods stocked on the Shuttle are processed for storage at room temperature and packaged in individual portions. Astronauts may tailor their menus according to their personal tastes, but within nutritional guidelines. NASA transferred various food items to the Museum after the mission.
