Scientific paper

On July 4, 2005 NASA's discovery mission Deep Impact will encounter comet 9P/Tempel 1. During this encounter, an impactor will be released, and will strike the nucleus, producing a crater that will be studied by a separate flyby spacecraft. In support of this mission, we propose to use Spitzer Space Telescope observations to characterize the dust environment around the nucleus, with two main goals in mind. First, these observations, in conjunction with observations from our existing ground-based database, promise to reveal fundamental information about the physical and chemical properties of the dust grains in the comet's coma, and these results can be used in comparative studies of the dust in other comets. Second, the data will be used in support of the DI mission, providing constraints on the grain properties that will be invaluable in the analysis of the encounter phase hazards.
