How is life in space different
from life on earth.
Answers
Answer:
In many ways, living in space is not very different from living on Earth. In other ways, it is quite different. Astronauts in orbit above Earth must do the same things inside their spacecraft to live as we do on Earth. They have to eat, work as a part of a team, exercise, relax, maintain hygiene and sleep. The only significant differences from living on Earth are that they operate in the confined space of the Space Shuttle orbiter cabin and that they, and all objects inside the cabin, float. Actually, floating is not quite the correct word to use because in order to float, astronauts have to have something on which to float.
Microgravity refers to an environment in which there is a virtual absence of gravity. For example, imagine that you and a friend are riding in an elevator car when the elevator cables break. As you plummet down the elevator shaft, you and your friend experience microgravity. In other words, you are falling together inside the car. This makes both of you appear to float.
Of course, gravity has not really gone away when you fall, but its effects inside the elevator car have. For example, what would the dial on a bathroom scale read if you could stand on it as you fall? Because of microgravity on the Space Shuttle, some jobs, like handling tools and fluids, become more difficult. If you are not careful, things will float away. Eating is also more of a challenge and so is going to the lavatory. Other jobs, however, become easier. Moving about is very easy and so is reaching the top shelf. Moving massive objects is easy because they feel light. Otherwise, it will collide with the inside walls of your spacecraft with the same force you used to get it moving.
