The European Space Agency Herschel mission will launch later this year. DEBRIS, or Disc Emission via a Bias-Reconnaissance in the Infrared/Sub-millimetre, was selected as a Key Project. The DEBRIS project will represent the most sensitive search toward main sequence stars for debris disks undertaken to date. The flux limited survey will be an unbiased search for dusty disk systems toward 450 nearby dwarf systems ranging in spectral class from A through M stars. The stars are drawn from the population of nearby main sequence stars. To get ready for the Herschel mission, the DEBRIS team has done a detailed literature search for information on the sample objects. One of the key components is the stellar age. Our survey, when complete, will allow us assess how the disk properties might evolve with spectra type as a function of stellar age. Here we present an overview of the DEBRIS program along with a preliminary discussion of the range of ages found to date among our sample stars.
