What does an astronaut (宇航员) eat in space? This is a question that
will puzzle many, as people rarely think of that. In the early space-travel
years, astronauts ate dehydrated (脱水的) foods that were eaten through
straws(吸管). In today's space-age, the food that they eat is totally different.
They eat food in the same way as people do on Earth.
Astronauts are able to prepare and eat a variety (多样化)of foods in
space. Some can be eaten in their natural form, like fruits; while some need to add water, like noodles. However, there are no refrigerators, so the food has
to be prepared and eaten without being Stored for a long time. When the
astronauts are hungry, they simply eat the food by opening the food ackages and with a fork, knife, and spoon.
Just like people on Earth, astronauts also eat three meals a day which
include breakfast, lunch and dinner. Sometimes they also eat snacks. The US
space agency NASA has found out that an astronaut's diet reduces(减少) by
about 70% on a space mission, though he has a wide range of foods to
choose from like nuts, chicken, beef, seafood, and candies. Drinks in the
spaceship include coffee, tea, juices, and lemonade.
Astronauts can also request a particular food that they would like to have in space. Scientists are always experimenting and trying out different space
foods that can be offered to astronauts when on space missions.
