We report the results of spectroscopic mapping observations carried outtoward protostellar outflows in the BHR71, L1157, L1448, NGC 2071, and VLA 1623molecular regions using the Infrared Spectrograph (IRS) of the Spitzer SpaceTelescope. These observations, covering the 5.2 - 37 micron spectral region,provide detailed maps of the 8 lowest pure rotational lines of molecularhydrogen and of the [SI] 25.25 micron and [FeII] 26.0 micron fine structurelines. The molecular hydrogen lines, believed to account for a large fractionof the radiative cooling from warm molecular gas that has been heated by anon-dissociative shock, allow the energetics of the outflows to be elucidated.Within the regions mapped towards these 5 outflow sources, total H2luminosities ranging from 0.02 to 0.75 L(solar) were inferred for the sum ofthe 8 lowest pure rotational transitions. By contrast, the much weaker [FeII]26.0 micron fine structure transition traces faster, dissociative shocks; here,only a small fraction of the fast shock luminosity emerges as line radiationthat can be detected with Spitzer/IRS.
