In a condition
of weightlessness, astronauts and other things inside the space shuttle
and the space station float.
Why do they float? Is it fun?
If you go outside on a cold day, you will have your shirt, pants, sweater,
perhaps long underwear, jacket, gloves, hat or hood, scarf and boots to
keep yourself warm. Now, think about what a spacewalking astronaut wear
in the outer space. Of course, he/she wears spacesuit.
What are the jobs of a spacesuit?
As we all know, there are no oxygen and water in the outer space.
How do astronauts keep themselves alive? Is there any difference between
living in space and living in the Earth?
Let's discuss about the questions!
