Altair is a star on the east of the Milky Way and Vega is a star on the west of the Milky Way. There is a Chinese traditional story about it Do you know it

Why do the scientists choose Mars
1. There are about 24 hours in a day.
2. There are four seasons, spring,
summer, autumn and winter.
3. We can see plain (平原),
mountains, tornado(龙卷风), and
atmosphere(大气层), and so on.
4. Scientists discovered methane (甲烷)
that means life.
Mars is similar to the earth.

With so many stars in the universe,
are we alone
Is there life in space
Have there been visitors to the earth from other planets
Did anyone communicate with us
There has been life on the earth for hundreds of millions of years.
What’s the scientists’ opinion about life
We haven’t found life on other planets.
Scientists always ask “Is there life out there in space ”
Scientists don’t think they will find life on them.
We’re not sure.
Do you hope there is life on other planets, galaxies or universes
Bad side
Good side
1. We can learn advanced(先进的) skills from them.
2. We can move there one day.
3. We can make friends with them.
4. Life means not only humans, but also plants and animals.
1. They may destroy our homeland.
2. They may kill humans.
