The first successful capture and return to earth of comet debris has amazed scientists. Among the expected inorganic chemicals, the organic amino acid glycine was detected — glycine was like a giant pearl in an oyster. What does this glycine story really mean?

Telescopes, Comets and Comet Tail Capture – Retrieval by Spacecraft of the Stardust Project

Telescopes are excellent research tools and reveal much about space. Comets are among the rhythmic, predictable visitors that streak across the sky, and comets can be photographed and instrumentally-studied by astronomers. The Stardust project was a bold venture of extending a scientific hand into space to touch and retrieve a comet's tail — it worked!

The Wild 2 comet has an orbital period of 6.39 years compared to the 2,320 year periodicity of the Hale-Bopp comet last seen in 1997. The Goddard Space Center Stardust team decided Wild 2 was an ideal candidate for a "Stardust" spacecraft comet-sampling encounter.
