Stardust's main objective is to capture material from comet Wild 2, with encounter scheduled for January 2, 2004, and to return these samples to Earth for analysis. The spacecraft will also collect interstellar dust from a recently discovered flow of particles from interstellar space that passes through our solar system. Scientists want to analyze the composition of this "stardust" to determine the history, chemistry, physics, and mineralogy of nature's most fundamental building blocks. Stardust's historic meeting with comet Wild 2 will be described in this talk, enhanced with images of the comet's nucleus and an encounter animation. Stardust's samples will be returned to Earth on January 15, 2006. To learn more about the Stardust mission, click here.
