摘要
国际空间站的建造成本超过1000亿美元,一套业余无线电装备则只要几百美元就买得到。这点也许在某种程度上能够解释,为何让人类最伟大的一项科学发明通过已逾百年历史的科技与地球沟通如此具有吸引力。不过,宇航员与业余无线电操作员多年来持续交谈一事,或许有更简单的解释。
The International Space Station cost more than.$100 billion.A ham radio set can be had for a few hundred bucks.Perhaps that explains,in part,the appeal of having one of humankind's greatest scientific inventions communicate with Earth via technology that's more than 100 years old.But perhaps there's a simpler explanation for why astronauts and ham radio operators have been talking and talking,for years.
