| Description | We propose a spatially-resolved far-infrared spectroscopic survey of asample of 23 nuclear and extranuclear regions within 22 nearby galaxies,selected to represent the broadest range of key physical properties,including luminosity, gas and stellar mass, star-formation density, andinfrared activity. Combined with our wealth of ancillary imaging andspatially resolved spectroscopy from the heritage of SINGS/KINGFISH andrelated surveys (ultraviolet, optical, infrared, low-J CO, and radio),the proposed SPIRE/FTS dataset will provide key insights into theprocesses that shape the interstellar medium and govern star formation.Detection of the continuum emission from large grains over 200-650microns will place new constraints on the long-wavelength behavior ofdust emissivity. The richness of the emission line spectrum in thiswavelength regime will allow us to quantify the excitation conditions ofCO over a wide range of environments, and to characterize the physicalproperties of warm and dense gas within galaxies on kiloparsec scales,interpreting these properties using models of photo- andX-ray-dissociated gas, and comparing directly with resolved tracers ofstar formation, heating, and AGN activity. With capabilities unmatchedby existing or planned ground- or space-based facilities, SPIRE/FTSmapping of a well-studied sample of nearby galaxies will serve as acrucial, unique, and lasting foundation for interpreting ALMAobservations of galaxies at high redshift. |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
