8. discuss the following questions with a partner. 1. have you ever looked through a telescope? what did you see? 2.what is a satellite? what are they used for? how would life be different without them? 3. would you like to be an astronaut? explain why or why not. 4. when do you think people will visit mars? what do you think they will find there? 5. should we try to discover other planets and life forms? Why or why not?

1. Yes, and I see the colorful galaxy, stars.

2. many planets have a satellite, our planet Earth has it too. They have an orbit who matches with both planets. Without them ,scientists suggest, the galaxy can literally fall apart!

3. I think thats a dangerous job, so I would prefer another.

4. in the future, they will definitely do this, because in the past, astronauts flew to the Earth-Moon satellite.

5. They can find many things, which do not exist on our planet. Maybe some aliens, and their ufo.

6. Why not? It is very interesting! for science especially.
