Deep Impact will probably be giving a fireworks show and it will all be on the 4th of July.

If all goes as planned, the Deep Impact spacecraft will release a wine barrel-sized probe on a suicide journey, hurtling toward the comet Tempel 1 — about 80 million miles away from Earth at the time of impact.

Here  is the news article.

Anyway, I'm not too sure I understand why they think revealing the core of a comet would reveal the origin of this solar system.

The materials in the comet should be very old.  On the order of Billions of years I guess.  Of course I could be totally wrong.

AFAIK comets are believed to originate from the Oort cloud, which is itself formed of material (debris) left over from the formation of the solar system.
