What do people eat in space? Is anything different? In the past the food wasn't good. Most food was in tubes and everybody complained. Now spacecraft are bigger, so we can take something fresh, usually fruit.
Is it difficult to eat in space?
In space everything floats because there is zero gravity so food is in special containers.
Does anybody cook in space?
There is an oven on the space shuttle, but astronauts don't prepare anything. They add water to the food and heat it.
Объяснение:
Вот ещё есть перевод:

Сложно ли есть в космосе?
В космосе все плавает, потому что там невесомость, поэтому еда находится в специальных контейнерах.
Кто-нибудь готовит в космосе?
На космическом шаттле есть печь, но космонавты ничего не готовят. В пищу добавляют воду и нагревают.
