Description We propose to obtain PACS full range spectra of 6 bright debris disks (with 70 micron fluxes >0.5 Jy) that have been spatially resolved in scattered light. We plan to search for far-infrared emission features due to water ice and other species. Herschel PACS is expected to be the premier tool for characterizing dust around debris disks because the grains in debris disks are believed to be (1) large (with minimum blow-out sizes great than one a few microns) and (2) cold (with typical grain temperatures less than 70 K). Our proposed sources possess high albedos, suggestive of water ice. A Herschel detection of water ice would be the first definitive detection of water ice in an external Kuiper Belt.

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.
