Title: Spatial Variations of Comet 103P/Hartley 2's Volatiles: Three Weeks of Deep Impact Data

In 2010, the Deep Impact spacecraft flew by comet 103P/Hartley 2 as part of its extended mission. Hartley 2 is a comet of significance because of its hi gh water production rates, making the mission the only flyby of a hyperactive comet. The Deep Impact spacecraft scans across the comet every 15 minutes to every hour so that the infrared spectrometer on board can create spectral maps of the coma at different wavelengths (1.05-4.85 microns). This techniq ue allows us to study the asymmetries in the coma, particularly of water and carbon dioxide. I will discuss the uniqueness of the flyby mission and the asymmetries and temporal variations evaluated throughout 23 days of observation through closest approach.
