We report on 14-35 micron spectral imaging of NGC 1333, a very young cluster in Perseus known for its large number of bipolar outflows. The long-lo slits of the Spitzer InfraRed Spectrograph were scanned over a region roughly 17x23 arcminutes, forming the largest area spectral mapping dataset obtained to date with Spitzer. 17 micron H2 S(1) rotational emission is widespread, with numerous bowshocks detected S of the cluster. Significant differences are seen between this emission and the HH object morphology seen at shorter wavelengths, including a large bubble-like structure N of SVS 13. Emission from H2 S(0), [S I], [Fe II], and [Si II] is detected in some of the brighter emission knots at 28, 25, 26, and 35 microns respectively. We also obtain continuum spectra of 40 cluster members.
