说明:如果你能飞越土卫六,你会看到什么?为了发现并更好地探索这颗奇特的土星卫星,美国航天局最近批准了一项任务,计划部署一架类似直升机的无人机——蜻蜓号飞越土卫六。土星的卫星土卫六是太阳系中最庞大的卫星之一,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。经过研发、建造、测试和发射,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、开始进行空中探索、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、化学作用和不断变化的地貌,而且能增强人类对生命最初是如何在我们年轻地球上演化的理解。

Robotic Dragonfly Selected to Fly Across Titan

Explanation: If you could fly across Titan, what would you see? To find out and to better explore this exotic moon of Saturn, NASA recently green-lighted Dragonfly, a mission to Titan with plans to deploy a helicopter-like drone. Saturn’s moon Titan is one of the largest moons in the Solar System and the only moon known to have a thick atmosphere and changing hydrocarbon lakes. After development, building, testing, and launch, Dragonfly is currently scheduled to reach Titan in 2034. The featured animated video envisions Dragonfly arriving at Titan, beginning its airborne exploration, landing to establishing a radio link back to Earth, and then continuing on to another trans-Titanian flight. It is hoped that Dragonfly will not only help humanity better understanding Titan’s weather, chemistry, and changing landscape, but also bolster humanity’s understanding of how life first developed on our young Earth.
