We present our results on the energy balance of the Deep Impact experiment based on analysis of 180 infrared spectra of the ejecta obtained by the Deep Impact spacecraft. We derive an output energy of 16.5 (+9.1/-4.1) GJ. With an input energy of 19.7 GJ, the balance is, within the uncertainties, in equilibrium. No other source of energy other than the impactor or the Sun is needed to explain the observations. Most of the energy goes into the hot plume in the first few seconds, which only represents a very small fraction (<0.01 %) of the total ejected mass. Here we also present the composition of the hot plume and the contribution of the different physical processes involved in the impact experiment. Our results emphasize the importance of laboratory impact experiments to understand the physical processes involved at such a large scale.
