Eating In Space
Eating in space is different from eating on earth . The food that astronauts carry with them does not look like the food you eat on earth .
Some food is carried in closed bags . It is cooked and frozen before the astronauts get it . All the water is removed from the food . In the space capsule (密封座舱) , the astronauts puts the water back . He “shoots”hot or cold water into the food bag with a special gun . He eats the food through a small hole in the bag .
Other foods come in bite sizes . The astronauts puts a whole piece in his mouth at a time . There can be no crumbs (碎屑) . Crumbs would float around the capsule and get in the way . Meat , cake , and cereal (谷类) often come in bite-sized pieces .
