What do you eat in outer space?

Answer 1

Space food is food products, specially created and processed for consumption by astronauts in outer space.Today, fruits and vegetables that can be safely stored at room temperature are eaten on space flights. Astronauts also have a greater variety of entrées to choose from, and many request personalized menus from lists of available foods including items like fruit salad and spaghetti. Astronauts sometimes request beef jerky for flights, as it is lightweight, nutritious, and can be utilized in orbit without packaging or other changes.

Designing food for consumption in space is difficult. Foods must meet a number of criteria to be considered fit for space; first, the food must be physiologically appropriate, specifically, it must be nutritious, easily digestible, and palatable. Second, the food must be engineered for consumption in a zero gravity environment. As such, the food should be light, well packaged, quick to serve, and easy to clean up (foods that tend to leave crumbs, for example, are ill-suited for space). Finally, foods must require a minimum of energy expenditure throughout their use, i.e., they should store well, open easily, and leave little waste behind.

Carbonated drinks have been tried in space, but are not favored due to changes in burping caused by microgravity.[13] Coca-Cola and Pepsi were first carried on STS-51-F in 1985. Coca-Cola has flown on subsequent missions in a specially-designed dispenser that utilizes BioServe Space Technologies hardware used for biochemical experiments. Space Station Mir carried cans of Pepsi in 1996.
