In the 1960s, during the earliest space flights, no one knew exactly how weightlessness would affect eating and drinking.
Would food fly off a plate? Would astronauts have digestive problems, with no gravity to help things along the digestive system? The first astronauts ate rather unappealing food pastes squeezed directly into the mouth from toothpaste-like tubes. Yuck!
Today, astronauts eat a variety of foods like steak, shrimp 1 cocktail 2, strawberries and butterscotch pudding. Each food is made as appetizing and simple to prepare as possible. Steak, for example, is cooked here on earth and sealed into a reheatable pack. Strawberries are freeze dried, keeping their shape and texture 3 when they’re rehydrated. It’s easy to get water in space, because the fuel cells that supply electricity for spacecraft produce water as a byproduct.
Containers of food have to be taped, magnetized, or velcroed to trays, and astronauts usually dine with foot restraints on-unless they feel like floating around! There’s usually enough liquid surface tension to keep food in its container, but bump a plate or fork, and watch your dinner drift away!
Liquids are even trickier 4. Juice won’t pour out of a container, but simply stays inside. If you shook it out, little globs of juice would fly everywhere! That’s why liquids are squirted directly into the mouth or sucked in with a straw from a sealed container. Once food is in the mouth, there’s no problem swallowing or digesting.
