    大国梦,嫦娥飞天。

         神舟飞天, 嫦娥奔月,到处都是欢呼雀跃,更加增添了“中华民族伟大复兴”者们的底气。可我还是心存疑虑。一个依靠半个世纪年龄的俄罗斯技术建造的飞船和一个没多大科学价值和技术创新的卫星值得欣喜的地方似乎并不多。毫无疑问,我们有了载人航天的技术能力,可喜可贺。可再想想,以欧洲航天局的技术条件要想送两个人到近地轨道转转恐怕不是什么难事。他们不做关键在于考虑到这样做的价值何在,代价几何。从技术上讲,这并没有多大的突破,三十多年前就可以做到了。从科学上讲,这没多大价值,不会提供我们多少科学发现。从代价上看,花销却无疑是极大。当然,从新闻价值,从荣耀感来说,这确实也很有鼓动感染力。明显的,欧洲航天局一番权衡之下,将资源投入到小型的,更有创造力和科学价值的探测器和无人飞船上比花在昂贵,危险但意义有限的载人航天上面更加明智。人类对太空宇宙的探索无疑是最激动人心,最具开拓进取精神的行为之一了。但这样的探索是美国人完成,是俄罗斯人实施,还是由中国人进行有何区别?宇宙的真相和壮丽对所有人类都是一样的。可是现在因为政治,意识原因大家单打独斗,重复劳动,浪费巨大也令人惋惜。如果能集合美国,俄罗斯,欧洲,中日的力量,人类重返月球并向火星进军相信要比NASA现在独力难支要容易得多。同时以中国现在极端的贫富差距,环境危机,同时再花费巨资做这样一定程度上的“面子工程”,要给它的必要性作辩护还是有点困难的。这样“复兴中华民族”还不如多修点学校来得更现实。
