【太空日渐“开放” 是人类的新乐园还是某些国家的新“战场”？】北京时间9月16日，在中国空间站天和核心舱工作生活90天后，三名中国航天员踏上了归“家”之路。而在当天，美国SpaceX公司也成功发射了其商业载人飞船，首次将“全平民”机组送入太空。太空技术飞速发展，浩渺星空逐渐向普罗大众伸出双手。这是否意味着人们很快就可以体验太空旅行？还是让某些国家又找了一个新战场呢？ On September 16, China's taikonauts left for home after 90 days in China's Space Station. American company SpaceX successfully launched its commercial manned spacecraft on the same day, carrying the first all-civilian crew into space. With the rapid development of space technology, the vast starry sky is gradually extending its hands to the general public. Does it mean space travel for everyone is around the corner? Or, for some countries, is another battlefield emerging? http://t.cn/A6MtvqAM
