astronaut

 I watched the movie about astronaut last year.
And I have interested in about it, especially how works they do.
So I researched about it.
According to the Jaxa's homepage,astronauts put the space machine
and the International Space Station into effect.
Also, they experient and observe in the Space.
They works not only in the space machine but also out of it.
It is very interesting.I want to research about it more.
