Life in space
A. The first astronauts to come into space only went up for short trips to see what it was like. Astronauts may now spend weeks or even months living and working in space. They live in a large spacecraft that they often call a space station, which circles or travels around Earth. The astronauts on board spend their days doing scientific studies such as examining the effects of space on the human body and the growth of plants. They also keep the space station running in the right way.
B. Living in space for a long time will affect an astronaut's body. Many astronauts get space sicknesses, such as a cold head, stuffy nose, or puffy face, shortly after entering space. That is because there is not enough gravity in space. Astronauts will have to exercise to stop their muscles from becoming weak. They also need to monitor their bodies to ensure good health and research the effects of space travel on the human body. Besides doing their jobs, astronauts do the same activities back on Earth. For example, they will eat their meals, sleep, relax and enjoy themselves.
C. Eating food in space is a real challenge. In space, everything will become weightless and start to float away. For instance, food will not stay on a plate, and drinks will drift away from a glass. For that reason, people will have to put them in some special packages, so the astronauts will be able to eat the food directly from the packages. For each space travel, astronauts will bring freeze-dried food. The food will become soft and sticky after the astronauts add water and heat them. They have fresh food delivery from Earth, too.
