For thousands of years, mankind has been fascinated by outer space. Nearly forty years have passed since man first landed on the moon. Now, some people think that space exploration is a pure waste of time and money. They pointed out that billions of dollars were spent on space research, but little information was brought back.

However, every coin has two sides. There are still most people who think that space exploration has more benefits. I agree with those people. Many new products, such as meteorological and communication satellites, are also products of the space program, which have benefited people all over the world. More importantly, mankind has acquired scientific knowledge about outer space.

We believe it will succeed! /bring more benefits in the future, which we can't even imagine now. Space exploration is a challenge to mankind. This is the reason why several countries are making constant efforts to explore space.

Dude, you talk too much. Leave an address and I'll send it to you! ! !
