The Deep Impact flyby spacecraft made its closest approach (700 km) to comet 103P/Hartley 2, the target of the Deep Impact eXtended Investigation (DIXI) mission, on November 4th, 2010 [1]. The HRI-IR spectrometer [2] monitored the coma throughout the encounter acquiring frequent spectral scans from 1.05—4.85 μm. Gaseous H2O and CO2 at 2.7 μm and 4.3 μm, respectively, were the dominant emission bands detected in these spectra and the distribution of these parent species was determined to be highly asymmetric [3]. There is more CO2 escaping this comet than other Jupiter Family comets, including Tempel 1 [4], the primary target of the Deep Impact mission. We will present continuing analysis of the coma asymmetries, composition, and production rates as well as their two-month evolution around perihelion, in order to better understand the chemistry of the near-nucleus coma, the heterogeneity of the outgassing of the nucleus, the source regions of the outgassing and the processes that drive the activity on Hartley 2.
