有必要进行空间探索吗
人类对外部空间着迷已有上千年的历史了。从人类第一次登上月球起至今已有40多年了。现在,有些人认为空间探索完全是浪费时间和金钱。他们指出,数百亿美元用于太空研究,但收获甚微。另外,用于研究的时间和金钱实在难以估计。
然而,任何事物都具有两面性。仍有大多数人认为进行空间探索利大于弊,我也非常赞同他们的观点。许多新产品,如气象、通讯卫星都直接得益于空间研究,使全球受益匪浅,而且人 类从中获得了不少关于太空的知识。
空间探索早巳使人类受益匪浅了,而且我们也相信,将来它会带给人类更多的好处,有些甚至是我们现在无法想像的。太空探索对我们人类来说是个挑战,这也是为什么许多国家不断进行探索的原因之一。
do we need space exploration
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 thct that it cost billions of dollars to can3 on the space research, but a little infrmation was brought back. in addition, the time and money spent on space exploration is too much to calculate.
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 benefitted people all over the world. and what s more. scientific knowledge about outer space has been acquired by the mankind.
we benefited a lot from space exploration. we believed that it will bring more benefits in the future, which perhaps 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.
