The largest ever spacecraft to be launched on a mission to another planet is Cassini. This NASA spacecraft reached Saturn in July 2004, carrying with it another smaller spacecraft: the European Space Agency Huygens probe. Huygens separated with Cassini on Christmas day 2004, and on January 14th 2005, descended to the surface of Saturn's largest moon, Titan. While the Huygens landing was a wonderful success, Cassini's work is far from over. Cassini will spend the next few years exploring Saturn and its many moons, and of course, Saturn's famous rings. Indeed the rings are Saturn's most recognisable feature, easily visible with a small telescope, and yet they are incredibly thin and are not solid bands of material. We see them because they are made of tiny highly reflective icy particles. On board Cassini is an instrument called the Cosmic Dust Analyser (CDA), the focus of this project. When the ring particles impact CDA, we can determine information about the composition of the particles. The rings are highly structured in terms of composition, and over the next few years, CDA will tells us about the nature and composition of particles from many different regions of the rings, and also about small particles ejected from the moons by impacts on their surfaces.

卡西尼（Cassini）是有史以来最大的航天器。该NASA航天器于2004年7月到达土星，并带上了另一个较小的航天器：欧洲航天局Huygens Proce。 Huygens于2004年圣诞节与Cassini分开，并于2005年1月14日下降到土星最大的月亮Titan的地面。虽然Huygens着陆取得了巨大的成功，但Cassini的工作还远远没有结束。卡西尼将在接下来的几年中探索土星及其许多卫星，当然还有土星的著名戒指。确实，环是土星最知名的功能，可以通过小型望远镜易于可见，但它们非常薄，不是固体材料带。我们之所以看到它们，是因为它们是由高度反射的冰冷颗粒制成的。卡西尼（Cassini）上是一种称为宇宙尘埃分析仪（CDA）的乐器，该项目的重点是该项目的重点。当环粒子影响CDA时，我们可以确定有关颗粒组成的信息。这些环在组成方面是高度结构化的，在接下来的几年中，CDA将向我们介绍来自许多不同区域的颗粒的性质和组成，以及关于通过对表面的影响从卫星弹出的小颗粒。
