大学生英语作文：我们是否需要太空探索
scientific knowledge about outer space has been acquired by mankind
Man has been fascinated by outer space for thousands of years. It has been almost over forty years since man's first landing on the moon. Now, some people believe that space exploration is a sheer waste of time and money. They point out the fact that it cost billions of dollars to carry on the space research, but a little information was brought back.
However, every coin has two sides. There are still a majority of other people who believe that space exploration has more advantages. And I agree with those people. Many new products, such as weather and communication satellites, are also products of space programs, and they have benefited people all over the world. And what's more, scientific knowledge about outer space has been acquired by mankind.
We believed that it wi!/bring more benefits in the future, which we can not even imagine now. Space exploration is a challenge to human beings. That's why several nations try hard to carry out space exploration continuously.
