Abstract NASA’s eighth Discovery mission, Deep
Impact, will arrive at comet 9P/Tempel 1 in July 2005. The spacecraft will
deliver a 370-kg impactor to the comet to excavate a large crater. The science
goals will be (a) to excavate down to unaltered material to learn about the
chemical and physical conditions in the early solar system and (b) to learn
about cratering processes in small bodies and the mechanical properties of the
cometary surface layers. In addition to optical imaging and near-IR imaging on
the spacecraft, there will be a world-wide network of professional ground-based
and space-based telescopes observing the event. A large role for mission
support from observers with small telescopes will be discussed in this paper.
