卡西尼-惠更斯号(英语:Cassini-Huygens)是美国国家航空航天局、欧洲空间局和意大利航天局的一个合作项目,主要任务是对土星系进行空间探测。卡西尼-惠更斯号土星探测器是人类迄今为止发射的规模最大、复杂程度最高的行星探测器。卡西尼号探测器以意大利出生的法国天文学家,土星光环环缝的发现者卡西尼的名字命名,其任务是环绕土星飞行。惠更斯号探测器是卡西尼号携带的子探测器,它以荷兰物理学家、天文学家和数学家,土卫六的发现者惠更斯的名字命名,其任务是深入土卫六的大气层,对土星最大的卫星土卫六进行实地考察。
1997年10月15日从肯尼迪航天中心发射升空的卡西尼—惠更斯号飞船于2004年07月到达土星周围。这个项目由两部分组成:卡西尼号轨道器会环绕土星及其卫星运行四年之久,而惠更斯号探测器则会深入土卫六浓雾包围的大气层并在其表面着陆。安装在这两枚探测器上的精密仪器将会为科学家们提供帮助弄清这片神秘而辽阔的区域的重要数据。
卡西尼—惠更斯号是不同国家的三个航天局的协作成果。有十七个国家参与建造了这艘飞船。卡西尼号轨道器由美国国家航空航天局下属的喷气推进实验室建造和管理。惠更斯号探测器由欧洲空间局建造。意大利航天局则为卡西尼号提供了用于通讯的高增益天线。来自世界各地总共超过200位科学家将会参与研究收集到的数据。
















































原名火星科学实验室(Mars Science Laboratory)的 Curiosity 号火星探测车,终于由 NASA 的科学家们从 60 个可能的地点中选出了最后降落的地点。这个名为 Gale 的陨石抗宽达 155 公里,而 Curiosity 瞄准的是坑内的一座小山附近。选择这里的理由,是因为它降落起来相对安全,而且附近就有疑似水成的地质结构 -- 虽然基本上已经可以确定火星上目前没有生命,但 NASA 希望藉由跟随着「水」的证据,可以确定火星在过去是否有生命生存的可能。(Quelle:http://cn.engadget.com)
