Dear Editor， We had a discussion over whether it’s necessary to carry out the outer space explorations at a class meeting the other Some of us think it important to research the outer First， people can get a better understanding of the outer space through their Second， new resources can be found there for humans to Third， explorations can possibly bring about new living space for human However， others don’t believe They say this kind of exploration costs too much And it’s very dangerous for astronauts to do such I think people should do the explorations and therefore such explorations into the outer space are worth trying Yours， Zhou Yong
Some people think， can gain new knowledge expanding human living space from space to obtain the new Others think don't agree because costly and astronauts safety problems
