价值连城的美国大型空间探测器“卡西尼”(Cassini),在经过长达7年、航行了几十亿千米的星际历程之后,终于在2004年7月1日进入土星轨道,开始它4年的环绕飞行。大约6个月后,该探测器将释放所携带的子探测器“惠更斯”(Huygens),它穿过浓密的大气到达土星的一个叫“泰坦”(Titan,又叫土卫六)的卫星。它们的主要任务是研究土星光环的三维结构和动力学状态,分析土星卫星的表面成分和地质史等。来自美同和欧洲的科学家将借助“卡西尼”携带的两架相机对土星的特征、卫星和光环作更深入的研
The cosmically large U.S. space probe Cassini finally entered Saturn’s orbit on July 1, 2004, after seven years of sailing the cosmic journey of billions of kilometers, 4 years of flying around. About six months later, the probe will release the carried sub-detector Huygens, which passes through the dense atmosphere to a “Titan” called Titan satellite. Their main task is to study the three-dimensional structure and kinetic state of Saturn’s aura and to analyze the surface composition and geological history of Saturn’s satellites. Scientists from the United States and Europe will use the two cameras carried by Cassini to do more research on Saturn’s features, satellites and aura
