Is space exploration significant? The topic of space exploration is becoming more and more popular recently. People have divided opinions about it. Some of us think it important to explore space because people can have a better understanding of the outer space through exploration. Secondly, with the resources on the earth running out, it is necessary to find new resources in the outer space. Thirdly, these explorations make it possible to find other planets which are suitable for humans to live on. However, others think very differently. They said this kind of exploration is a waste of time and money. Besides, it is extremely dangerous for astronauts to explore space, so sometimes they risk their lives in finishing the mission. As far as I’m concerned, people should be pioneering. Although there are huge risks and difficulties, it is worth carrying on space exploration.  Sample Thanks! 35 $
