The Russian space program has included tinned food in their provisions, including puréed meat served from toothpaste tubes, as eaten by Yuri
Gagarin on Vostok 1 in 1961. NASA packed their space food in pouches and sealed containers which could be strapped onto trays to avoid food floating away with
microgravity. This has all moved on from the early days of space travel, where the sole nourishment were thick tasteless liquids in tubes, bite sized cubes and freeze-dried
powder. Food was basic and unpopular with the space crews, which pushed one astronaut to smuggle aboard a corned beef sandwich, causing much consternation at
ground control, all extremely concerned that the crumbs could damage air vents or be inhaled.
