2.登上火星

   1997年,美国“旅居者”火星车降临火星,燃起了人类登上这个红色星球的愿望。2003年6月2日和6月10日,欧洲宇航局的“小猎犬2号”火星探测器和美国航空航天局(NASA)的“勇气号”火星车相继升空,并预计于今年底和明年初登陆火星。此外,6月25日,另一枚运载火星车的飞行器也将升空,有关火星的话题不断升温,其中,载人登陆火星探险的话题也被科学家提上了议程。 往返火星的行程至少长达1年,如果实验证明人类完全可以适应这么漫长的“火星之旅”,那么,2015年左右人类就有可能登陆火星!事实上,NASA早在15年前就提出了“人类登陆火星”设想,现在又把这种设想变为更为细致的报告。该报告提出,从地球前往火星的载人飞行可能将耗资4500亿美元,需要建一艘像足球场一样长的核动力太空船,在里面装载足够人类往返火星一年途中所必需的各种生活设备和运行燃料,此外,还提出了多种载人登陆火星计划的可行性等。
