The unprecendented spatial resolution and sensitivity of SIRTF at mid- and far-IR wavelengths will allow detailed images of the distribution of and relative importance of non-thermal nuclear emission, stars, gas, dust, and star formation activity for nearby, bright galaxies. This observing program targets a representative sample of 101 galaxies in the local universe for IRAC and MIPS photometry from 3.6 to 160 um, and IRS step-and-stare spectroscopy to cover the 7.7 um PAH feature. The goals of the project are: to resolve spatially various components of the mid- and far-IR galaxy emission as a function of galaxy type and luminosity; to calibrate UV, Halpha, and far-IR estimators of the unobscured star formation rate; to determine the stellar masses using the shortest wavelength data; to create a nearby galaxy sample suitable for comparison with higher redshifts; and to construct a mid-IR "Hubble Atlas."
