This image illustrates one of several ways scientists have begun
extracting comet particles from the Stardust spacecraft's collector.
First, a particle and its track are cut out of the collector material,
called aerogel, in a wedge-shaped slice called a keystone. A specialized
silicon pickle fork is then used to remove the keystone from the remaining
aerogel for further analysis.
