登陆土星的卫星土卫六会是什么样子？2005年，欧洲航天局的惠更斯号探测器降落在太阳系最多云的卫星上，并拍摄了它下降的延时视频。惠更斯号在2004年底进入土星轨道后不久就与机器人卡西尼号宇宙飞船分离，并开始接近土卫六。惠更斯号在抵达土卫六两小时后，向土卫六表面坠落，起初只记录了这颗被遮蔽的卫星不透明的大气层。这个电脑控制的卡车轮胎大小的探测器很快展开了一个降落伞来减缓下降速度，穿过厚厚的云层，开始传输一个从未在可见光下见过的遥远的奇怪表面的图像。惠更斯号降落在干燥的海面上，存活了90分钟，传回了一个奇怪的深色沙质平原的独特图像，上面散布着光滑、明亮、拳头大小的冰岩。

What would it look like to land on Saturn's moon Titan? The European Space Agency's Huygens probe set down on the Solar System's cloudiest moon in 2005, and a time-lapse video of its descent images was created. Huygens separated from the robotic Cassini spacecraft soon after it achieved orbit around Saturn in late 2004 and began approaching Titan. For two hours after arriving, Huygens plummeted toward Titan's surface, recording at first only the shrouded moon's opaque atmosphere. The computerized truck-tire sized probe soon deployed a parachute to slow its descent, pierced the thick clouds, and began transmitting images of a strange surface far below never before seen in visible light. Landing in a dried sea and surviving for 90 minutes, Huygen's returned unique images of a strange plain of dark sandy soil strewn with smooth, bright, fist-sized rocks of ice.
