Tempel

Tempel 1 is a pickle-shaped comet, some four- by twelve-kilometers in size, that orbits the sun between Mars and Jupiter every six or so years.

NASA scientists say everything remains on course for what promises to be Monday's spectacular rendez-vous between the Deep Impact space probe and the comet, Tempel 1. The announcement follows the separation of the "impactor" from the fly-by space craft, which will record the massive collision.
