We describe a key programme using the unprecedented sensitivity and spatial resolution of Herschel for a comprehensive far-infrared photometric survey of the extragalactic sky. Blank field surveys using PACS at 170, 110 and 75micron are supplemented with targeted observations of massive zvirgul1 clusters and lensing clusters. We will resolve the bulk of the Cosmic Infrared Background, determine the nature of its constituent sources and trace the evolution of dust-obscured star formation. Our survey will study the evolution of galaxies and AGN over a wide range of redshifts and in environments of different density, and provide the crucial far-infrared measurements lacking for a full understanding of intermediate and high redshift galaxy populations previously identified at other wavelengths. We have chosen fields with excellent multi-wavelength coverage enabling both rapid science results and a lasting legacy value. This survey is coordinated with Herschel/SPIRE observations of the same fields in a Key programme submitted by the SPIRE SAG 1.

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.
