Imagine driving through heavy fog to a place you ve never been, guided only by a faint taillight in the distance. The challenge is similar to one NASA will take in January 2004by flying its Stardust mission through the halo of dust that surrounds the nucleus of a comet. With Mars and other planets, we know relatively well wherethe planets are, said Dr. Shyam Bhaskaran, a Stardustnavigation specialist at NASA s Jet Propulsion Laboratory inPasadena, Calif. This is not the case with comets, whichare not easily observed because they are small objects withgas jets. It is much harder to predict their orbits, whichis why we have a little extra help from a camera onboard thespacecraft. One of three methods the Stardust navigation team is usingto find their way, optical navigation involves placing a200mm focal length camera onboard the spacecraft as it fliesto its target, a comet called Wild 2 pronounced Vilt .

These images continuously help engineers on theground figure out where the spacecraft is in relation to thecomet.
