The Stardust Mission
星尘使命
In January 2004, the Stardust spacecraft flew through the coma of comet Wild2 and captured thousands of cometary dust grains in special aerogel collectors. Two years later, in January 2006, Stardust returned these dust grains—the first sample return from a solid solar-system body beyond the Moon—to Earth. In addition, Stardust carried an equally important payload on the opposite side of the cometary collector: the first samples of contemporary interstellar dust ever collected. Certain types of ancient interstellar dust—older than the Solar System (about 4.6 billion years)—have been isolated from meteorites and analyzed. In contrast, the interstellar dust collected by Stardust comes directly from local interstellar space. As well as being the first mission to return samples from a comet, Stardust was the first sample return mission from the Galaxy! However, finding the incredibly tiny interstellar dust impacts in the Stardust Interstellar Dust Collector (SIDC) will be extremely difficult.
在2004年1月，星尘号飞船从“怀尔特2”彗星的彗发中穿过并用专门的气凝胶收集器捕获了数千彗星尘埃颗粒。两年后的2006年1月，星尘号带回这些尘埃颗粒——首批带回的来自月-地系统之外的太阳系自身样品。此外，星尘号彗星收集器的背面还携带着同样重要的载荷：第一次采集到的（和太阳系）同一时期星际尘埃样品。一些类型的古老星际尘埃——比太阳系（大约46亿年）还要早——已经从陨石中分离出来并分析过了。与之相反，星尘号收集的星际尘埃直接来自星际空间。同首次将彗星样品带回一样，这也是第一次将银河系的样品带回来！然而，在星尘号星际尘埃收集器（SIDC）中寻找异常微小的星际尘埃是极为困难的。
The Stardust spacecraft was launched in 1999. It carried a two-sided hypervelocity particle collector consisting of an array of tiles made of a strange material called aerogel. The array is about 40 cm (16 inches) in diameter. Aerogel has extremely bizarre properties. It is a solid, glassy nanofoam, yet weighs next to nothing. Aerogel has the almost magical property that it can capture particles moving at very high speeds (several miles per second or more) better than any other material. In some cases, particles can be captured in a nearly pristine state. Particles moving at these speeds vaporize if they hit any other material.
星尘号飞船于1999年发射。它携带着一个双面的超高速微粒收集器，收集器是由一种称作气溶胶的奇特物质制成的瓦块阵列。阵列直径40cm。气凝胶有一些非常特别的性质：是固体的，类似玻璃的微小泡沫，但是几乎没有重量。气凝胶有着不可思议的性质，它可以比其他任何材料更好的捕获以非常高速度（每秒数英里甚至更高）运动的微粒。在某些情况下，能够以最接近微粒原始状态捕获它们。微粒以这样的速度撞上任何其他物质会被蒸发掉。
Before its encounter with the comet Wild2 in January 2004, the Stardust spacecraft raised its collector two times into the interstellar dust stream. Stardust collected a few dozen interstellar dust particles during this time. Nobody knows what the typical interstellar dust grain looks like. This is the very first sample of solid material from the local interstellar medium ever to be returned to Earth for analysis. The challenge is to find them in the aerogel collectors. We expect that the best way to find these particles is by searching using the human eye. Your participation is absolutely critical to the success of this project.
在星尘号同“怀尔特2”彗星于2004年1月相遇前，星尘号两次在星际尘埃流中将它的收集器升起，在此期间星尘号捕获了数十个星际尘埃微粒。没人知道典型的星际尘埃看上去是什么样的。这是第一次将局部星际介质中的固体物质带回地面研究。面临的挑战是将它们从气凝胶中找出来。我们认为找到这些微粒最好的方法是用肉眼搜寻。你的参与对本项目的成功是绝对关键的。
