Do We Need ace Exploration Man has been fascinated by outer ace for thousands of years, It has been almost over forty years since man s first landing on the moon. Now, some people believe that ace exploration is a sheer waste of time and money. They point out the thct that it cost billio of dollars to can3 on the ace research, but a little infrmation was brought back. In addition, the time and money ent on ace exploration is too much to calculate. However, every coin has two sides. There are still a majority of other people who believe that ace exploration has more advantages. And I agree with those people. Many new products, such as weather and communication satellites, are also products of ace programs, and they have benefitted people all over the world.
