MICRO GRAVITY

IN MICRO GRAVITY EVERY THING FLOAT

the chalrnge

In space, astronauts face microgravity better known as "zero gravity." While microgravity makes everything float including themselves, it makes astronaut space cooking a challenge as it alters the physics of the food they prepare.

With no convection heating capabilities, astronaut cooking makes it impossible to be able to prepare a hot cup of coffee. However, astronauts are able to avoid a completely cold cup of coffee by simply (using a spoon) stirring their coffee.The lack of convection also makes deep frying a challenge as oil fluid cannot fully be heated for an item to be cooked in. Not having convection also creates a challenge for being able to boil and heat water.

Astronauts typically eat prepared meals. And according to sources at the Smithsonian National Air and Space Museum, sstronauts use three different types of prepared meals: freeze dried, refrigerated and canned. These meals follow the premise of being "lightweight, compact, tasty and nutritious, [and] also [kept] for long periods without being refrigerated."
