Everybody acknowledge that there are twelve remarkable planets in the solar system such as Mercury, Venus, Mars,  Jupiter, and ets . However, there is only one we can life in it it is the earth. The earth is a planet which has a H2O and Oxygen that  make all organism  animal  ,people , or even Insects . Also there is in the solar system sun and moon .  The sun give the earth  the warm and  light  and  the moon reflects the light of the sun on the ground in the night. Scientists know this information , But the important question is " is space exploration important or not?" there is many advantages and disadvantages of consider that .

By exploring space. we can discover a new planet  we can life in it . if we are not our children. there are a lot of useful inventions which need satellites in the space to work properly. for example, the big everyone has it in their phone or laptop is map Google.In addition, There are many students graduate from university and sober out of work this thing makes them acquire knowledge and money at the same time.

The disadvantages are many people who are travel to the  space  is lost or died because of the lack of food and water. Futhermore, they need many times and days and months  to discover something new.

In my opinion, studying and researching about  the space exploration is very important and not wasting time. Also the development  of the life every day  make us search about that   and the huge  and  usefull thing  of exploring the space is the technology.
