Explanation: If you could fly across Titan,what would you see? To find out and to better explore this exotic moon ofSaturn, NASA recently green-lighted Dragonfly, a mission to Titan with plans todeploy a helicopter-like drone. Saturn's moon Titan is one of the largest moonsin the Solar System and the only moon known to have a thick atmosphere andchanging hydrocarbon lakes. After development, building, testing, and launch,Dragonfly is currently scheduled to reach Titan in 2034. The featured animatedvideo envisions Dragonfly arriving at Titan, beginning its airborneexploration, landing to establishing a radio link back to Earth, and then continuingon to another trans-Titanian flight. It is hoped that Dragonfly will not onlyhelp humanity better understanding Titan's weather, chemistry, and changinglandscape, but also bolster humanity's understanding of how life firstdeveloped on our young Earth.
蜻蜓号飞越土卫六
如果能够飞越土卫六，你会看到些什么？为了更好地探索这颗神奇的名为泰坦的土星卫星，NASA最近批准了一项最新任务，部署一架名为蜻蜓号的无人机飞越土卫六。土星的卫星土卫六是太阳系最大的卫星之一，也是已知唯一一颗拥有浓厚大气层和不断变化烃湖的卫星。蜻蜓号目前计划在2034年抵达土卫六。这段精彩的动画视频展望了蜻蜓号抵达土卫六，进行空中探索，着陆后与地球建立无线电连接，然后继续另一次飞越土卫六的过程。我们希望蜻蜓号不仅能帮助人类更好地了解土卫六的天气和不断变化的地貌，而且能够增强人类对生命最初如何演化的理解。
