Through this discussion, some classmates are in favor of space exploration, they think that we may gain more new knowledge, we canunderstand the universe better,we will obtain the new resources from space. It may also extend our living space.
Of course, some have oppositions, they think that would cost too much money, the safe of astronaut will be a problem.
In my opinion , space exploration is very significant, which willimprove our knowledge and make usknow more about human living space.
